Car Maintenance: Valve Adjustment : Acura Cylinder 1 Intake Valve Adjustment: Part 1
Rocker Valve Can you drive with a faulty Rocker Valve?
My car is a 1.4 renault clio. There was a burning smell coming from the car. I realised that there was oil leaking from the car. Its not a massively bad leak, as its not actually coming through the car onto the road or anything. But apparently the burning smell is the oil burning with the heat of the engine. My uncle who is a mechanic believes it is the rocker valve and is going to replace it. Problem is he lives about 100mile drive away. Could a i drive the car this far do you think?
Faulty 'rocker valves' do not cause external oil leaks.
There's something else wrong with your engine, and anyone who believes he can diagnose mechanical problems with an engine from 100 miles away is a fool. Get it checked out locally before you do more harm.

Single Cylinder Is a gas powered 33cc 2-storke single cylinder scooter any good,,, from candain tire?
UPS AND DOWNS PLEASE
depends on what you want it for and being 2 stroke you have the chance of forgetting to add oil to the gas and burning the motor up and 2 stroke runs at higher rps witch means more wear but they have less internal parts to break but a 33cc is the size of a bigger gas weed trimmer and the small pocket rockets are 49cc and smaller older suzuki mopeds are 49cc and only go about 30-45mph depending on the driver weight, wind, incline, fuel/air mixture but the pocket rockets can go around 60mph with a 200lb driver on flat ground so depending on how far your going to ride/drive it and if there is any hills and depending on if your forgetful and might forget to add the right ammount of oil to the gas their easy to burn up if you need anything IM me or e-mail me scar592@yahoo.com i work on small engines and dirt bikes, lawn mowers, 2 stroke boat motors and basically anything i can work on i wil work on it

Reciprocating Seals for Hydraulic Cylinders
The most common fluids used in hydraulic systems are mineral oil based. In recent years, there has been a lot of attention paid to environmentally acceptable hydraulic fluids, but their use, so far, is limited, mainly because of their relatively high-cost compared with mineral oil. In many cases, standard reciprocating seals can be used in these fluids. Fire resistant fluids, such as high water based fluids, have applications in particular areas such as long-wall mining and have led to the evolution of specialised seals, but the vast majority of applications use hydraulic mineral oil. Two main factors affecting mineral oil based systems are cost and leakage.
This article looks at two key subjects:-
• The effect of tube finish on seal performance – the lowest cost tube may not give the desired performance
• The influence of the wiper on the leakage from the gland
THE EFFECT OF TUBE FINISH ON SEAL PERFORMANCE
A piston seal for a hydraulic cylinder is only part of the sealing system. Its life will depend on a number of factors, a major one being the nature of the surface against which it is running. Steel hydraulic cylinder tubes generally have a surface finish which is produced in one of three ways: -
• honing
• roller-burnishing
• drawing over a mandrel (DOM)
Hallite Seals have carried out major studies on the performance of double acting seals, used in both a double acting and single acting manner examining the affect of the method of tube manufacture and, hence, tube surface texture, on the performance of a typical double acting piston seal.
Cylinder Tube Manufacture
Hydraulic cylinder tubes are generally made from steel which is drawn over a mandrel (DOM). This process work hardens the material and gives it desirable mechanical properties. The final tube surface is obtained in one of three ways. In the honing process the tube is machined to gain the required roundness and bore tolerance and to remove surface imperfections, then finished by internally grinding or honing. In skived and roller-burnished tube the tube is again internally machined (skived) and flattened by rollers on the machining head. More recently drawing techniques have been developed such that the tube is considered ready to use in the as drawn state. This is known as special smooth inside diameter (SSID) or 'smooth bore' tube.
In terms of finished tube cost the ranking starting with the cheapest is SSID DOM, roller burnished and honed. SSID DOM tube can be 30% cheaper than roller-burnished, so its attractions to the cylinder builder are obvious. However, the quality of such tubes can be an issue which could lead to premature seal failure.
The Limitations of As-Drawn (SSID) Tube
SSID tube has been found to have limitations in application, particularly where the double acting piston seal is being driven into pressure. This can happen, for instance, when the lowering of a load is being controlled by the release of fluid from the full bore. The process of manufacture of as-drawn tube results in axial scoring of the tube; in roller-burnished and honed tube, such defects are eliminated by the finishing of the tube in a circumferential direction. These axial scores can provide sites for the fluid to jet over the seal eroding the contact face, particularly when the seal is being driven into pressure. A further difficulty is that such defects are not detected by the usual methods of surface finish measurement.
THE INFLUENCE OF THE WIPER ON GLAND LEAKAGE
The gland sealing system of a hydraulic cylinder consists of a number of elements, including the seal housings, the rod seal, the rod wiper, the rod bearing, the hydraulic fluid and the rod itself. Rods are generally hard chrome plated and relatively consistent in finish. The rod wiper has the primary function of preventing external contamination reaching the rod seal and gland bearings, and for this reason is fitted to the vast majority of hydraulic cylinders. However, this component has often been omitted in the laboratory testing of reciprocating seals.
Extensive studies have been carried out on the factors affecting reciprocating seal performance including the counter-face surface finish and the effects of contamination.
Hallite Seals carried out a series of tests where the leakage performance of five different wipers working with a common polyurethane rod seal was assessed. It is shown that he wiper is an important factor in the control of leakage from the hydraulic cylinder gland. Single lip wipers can give a much greater leakage than the seal, on its own, without a wiper. This is the result of the wiping lip collecting the oil on the rod, which provides the boundary lubrication to the seal. The use of double lip wipers reduces the leakage to the level of that of a seal on its own, but there is a danger of pressure trapping between the seal and the wiper. A double lip wiper profile has been developed, which minimizes the ring of oil on the rod collected by the wiping lip, and also has a venting feature to release the oil in the case of a pressure build up between the seal and wiper.

Engine Aircraft Has a seperate engine to run the superchargers for a multi-engine aircraft been done?
Seems like running a diesel engine, perhaps with a compressed air storage tank might increase the efficiency of a supercharged engine.
The engine powering the prop would be relieved of the energy robbing job of forcing air into the engine.
Been done? Would it work?
Back in the old days of radial engines the need to maintain horsepower at altitude became harder and harder as heavy transport aircraft and military bombers reached higher altitudes and thinner air.
They came up with the idea of Turbo Compounding an engine. They used the exhaust gas to spin an impeller or turbine wheel simular to how engines are Turbocharged today. However they didn't use this energy to pump air into the induction syster like a Turbocharger does.
The impeller or turbine powered and applied energy through a series of clutches directly back into the crankshaft. Wright built a 18 cylinder radial engine, the Wright R-3350 Turbo-Compounded Cyclone. It used three exhaust powered turbines to drive the clutches and apply it to the crankshaft. It was one of the most if not the most powerful aircraft engine of it's day. I believe the origional version produced somewhere around 2700 horsepower, and Turbo-Compounded it jumped up to about 3600 horsepower. The engine was also centrifically supercharged for the induction system to allow it to maintain manifold pressure at altitude. It worked well as you can see from the horsepower increase. However this was all taking place at the Dawn of the Turbine Engines. And with the success of the Turbine Engine development stopped for large displacement multi-cylinder piston engines. I am pretty sure that Wright was the only engine builder to use turbo-compounding, and it was also specific to just this one engine. As successful as this technology was, I would have to think that it was pretty maintance intensive to keep the system up and running. Just thought I would share this with you.
Based on a course on gas turbine engine controls developed and taught by the authors to Air Force, Navy, and Army engineers, this book covers the design of engine control and monitoring systems, for both turbofan and turboshaft engines. It focuses on four

Aircraft Propulsion is an engineering textbook written for students in aerospace and mechanical engineering. The book covers aircraft gas turbine engine and rocket propulsion from its basic principles to more advanced treatments in engine components. Propulsion system integration with aircraft plays an important role in understanding propulsion and is thus addressed in the book. Extensive review material and derivations are intended to help students navigate through the subject with more ease. Over 100 examples and 300 problems are designed to practice the principles learned in jet propulsion and compliment learning through applications. In every engine component, issues related to manufacturing, material properties, temperature limitations and cooling are included to give students an appreciation for the broader scope of propulsion engineering than just aero-thermodynamics. Component matching and off-design analysis is detailed in a separate chapter to provide the physical and performance linkage between the components and their impact on aircraft engines. Principles of chemical rocket propulsion are presented in the context of single-stage to orbit propulsion needs of a rocket-based combined cycle vehicle. The broad treatment of the gas turbine engine cycles and components makes the book suitable as a reference for propulsion and turbomachinery engineers, gas turbine industry and professional development courses.

Flight News On Aircraft Owners & Pilots Association Annual Aviation Summit Held In Long Beach,California In 2010 Raises Spirits
Nearly ten thousand pilots and aviation enthusiasts gathered in Long Beach, California, recently for the 2010 Aircraft Owners and Pilots Associations (AOPA) annual Aviation Summit to hear from industry leaders, see the latest and greatest, from aircraft to engines and avionics to pilot supplies, and to attend more than 60 hours of educational forums.
Hundreds more from the local community came out to see the aircraft on display at Airport fest, which was free and open to the public. Registered attendance for the 2010 Aviation Summit was 9746 and altogether 1101 aircraft flew in for the three-day event.
At Airport fest, 11373 people-a mix of registered attendees and members of the local community –came out to get an up-close look at all the planes. Three days of beautiful weather brought throngs of people to the airport, where an array of more than 80 aircraft provided a chance to see how far aviation has advanced.
Glass cockpit avionics, ballistic parachutes, and other safety features were on prominent display. Exhibitors and members are already looking forward to next years AOPA Aviation Summit, to be held next September in Hartford, Connecticut. More than 100 booths have already been reserved for next year by exhibitors at this year Aviation Summit.
The main hall at the 2010 event hosted about 500 exhibitors, and the schedule included programmes and speakers for new pilots, seasoned fliers and enthusiasts. A variety of social events and fundraisers were held.
Among the industry updates, cirrus Aircraft co-founder, Dale Klapmeier, discussed the Vision SF50 personal jet and the new perspective ESP flight-stability-augmentation system.
The Terrafugia crew showed their proof-of-concept "flying car" inside the main exhibit hall. Cessna and Bye Energy had an update on their progress toward building and electric-powered Skyhawk
Long Beach Airport hosted static displays, including Fifi; the only flying B-29 Superfortress.To get to the show saw Fifi make its first long cross-country flight in six years. The Commemorative Air Forces (CAF) freshly re-engined B-29 Fifi is the only airworthy example of its kind anywhere in the world and it was on display as part of AOPAs Summit.
The aircraft is running on four new custom engines that are a cross between the R-3350-95W and the R-3350-26WD .They were installed through two years hard work of volunteers and thanks largely to the financial backing of Jim Cavanaugh.CAF plans to take Fifi on tour soon.
Long Beach, 38th-largest city in the USA, has grown with the development of high-technology and aerospace industries in the area. It is known for the homes of major aerospace companies. Douglas Aircraft Company (later McDonnell Aircraft Corporation and now part of Boeing) had plants at the Long Beach Airport where the companies built aircraft for World War 11, and later built DC-8s, DC-9s, DC-10s, and MD-11s.
Boeing built the Boeing 717 until 2006 and continues to build the C-17 Globe master 111 strategic airlifter in Long Beach .Even after greatly reducing the number of local employees in recent years, Boeing is still the largest private employer in the city.
More than 100 flight training professionals, from certificated flight instructors through educational content providers to flight training device and aircraft manufacturers, gathered in Long Beach to attend a day-long Flight Training Summit Sponsored by the AOPAs flight training magazine. During the day, they heard new research into why student pilots drop out, and discussed how to help more of them complete their training.
The summit meeting was the first public step in AOPAs flight training student retention initiative.
"This is beginning of a national conversation on growing the pilot population," said AOPA president and CEO, Craig L. Fuller, during his opening address. "It is something that will affect all of us for years to come. I believe we can make a difference to the future of general aviation, but only by working together."
Electric Cessna 172
Bye Energy says its electric-powered Cessna 172 will be much more than an air show curiosity .In fact, the company told the press that it hoped to revolutionize the Part 23 training market with the aircraft.
"Our clear focus is mainstream aviation," company president, George Bye, said."It's ideal for training."
Bye said the aircraft would be a two-place model with an endurance of two hours on a combination of battery power, solar and power reclaimed from wing tip devices intended to capture vortex energy in flight and by the push on the propeller during descent. He said the company intended it to be"the point of entry for new pilots."
Bye added that the 172 was the ideal platform for the aircraft because it was already the most popular training aircraft in the world. By making it electric, operating costs would drop dramatically (he is predicting $ 5-$10 an hour in energy costs) and the TBO of the 180-horse-power, 42-pound engine was estimated at as much as 25000 hours.
The resulting 172, which the company hopes will fly in early 2011, will look a little different. The cowling will be tapered for the much smaller motor and that means virtually the entire propellers thrust will be used for movement, rather than the significant amount that is used for engine cooling in current models. The conforming aircraft will have a six-bladed composite propeller but the proof of concept will have a conventional two-blade propeller. The weight shed by getting rid of the piston engine and the fuel it needs will be taken up by lithium ion batteries and the weight and balance is not expected to change.
New R66 Makes Its Debut
Robinsons R66 hopped over from its home port Torrance. It is a newly certified five-place Rolls-Royce turbine-powered helicopter now available from Robinson, which hopes to fit the aircraft into the market between its own very popular piston R44 and more expensive light turbine helicopters.
The turbine blends vastly improved high altitude performance and load carrying capabilities with a moderate increase in fuel burn. The R66 burns about22 gallons in the same hour its piston sibling burns closer to 15.
As company president Kurt Robinson told the press, aside from the added capability and some nuances specific to turbine helicopter operation" the aircraft actually handles very similar to an R44, it just does it with a 300-horsepower Rolls-Royce turbine."
Cirrus Sends Upbeat Signals
Preference for Cirrus aircraft continues at all time high levels as the newest model in the best selling line-the SR22T-made its global debut.
"We see several positive factors combining to push our piston market share higher in a tough market" noted Todd Simmons, vice president, marketing."Most impactful in the third quarter was the introduction of the SR22T with its all-new TCM TSIO-550-K engine installation.
"This latest iteration in the best-selling SR22 line is not only a performance leader but also defines the path forward around future fuels.
"For the third quarter, the new model accounted for nearly 40% of the total deliveries right out of the gate .Additional new product features including Electronic Stability and Protection in the Cirrus Perspective by Garmin avionics suite, certified flight into known icing, and new personalization options are driving sales and delivery activity as well," he said.
Simmons added: "Of couse, the airframe parachute is as much a topic of discussion today as it was when we introduced CAPS as standard on every Cirrus more than a decade ago. The only difference is now we don't talk about how it works or why to have it, but instead what an invaluable safety feature it has proven to be and why would anyone own a plane in this class without it."
Mustang Gains Popularity
The Citation Mustang, already a star as an entry-level business jet around the globe, is fast becoming one of the most versatile as well, as customers continue to expand its role, thanks to its performance efficiency and low operating costs.
"We knew the Citation Mustang would be popular the world over as a business jet ,both as an owner-flown aircraft and in traditional on-demand roles, but we are finding our customers leading us to define new applications such as training and special mission work," said Jack Pelton,Cessna Chairman, president and CEO at AOPA Summit.
Earlier this year, Cessna delivered five Mustangs to Singapore Airlines for its pilot training programme.In July, Cessna teamed with Spectrum Aeromed to offer a medical evacuation system for the Mustang.
Cessna recently announced a new High Sierra Edition Mustang featuring luxury editions of the three currently offered interiors, a special paint scheme, a Garmin G100 with synthetic vision technology, electronic charts and locking fuel caps, as well as unique service and parts programmes.
Cessna announced that production of the 162 Sky catchers continued to increase. Cessna was on target to delivery 30 Sky catchers by the end of the year and more than 150 in 2011.
The Sky catcher features the Garmin G300 avionics suite and a Teledyne Continental O200D engine. The two-seat, single-engine aircraft has maximum speed of 118 knots with a maximum range of 470 nautical miles.
Piper Planes on Display
Piper exhibited a mock-up of its new single-engine, single-pilot business jet. In addition, the company displayed other single-engine aircraft, including the turboprop Piper Meridian and Matrix piston-powered cabin class aircraft, Archer light single and Piper Sport LSA.
"This will be the first time that the Piper jet Altaire mock-up is on the West Coast, and we are anticipating strong interest at this important AOPA venue," said Randy Groom, Piper executive vice president. "It is the logical extension of the renowned Piper single-engine product line that aircraft owners and pilots have been aspiring to for decades," he added.
WAAS/LPV Upgrade on Premier IA
Hawker Beech craft Services announced at the summit that it was taking orders and scheduling wide area augmentation system (WAAS) upgrades on Rockwell Collins Pro Line 21-equipped Premier IA aircraft.
This installation follows the introduction of the King Air C90GTi and 200/300 upgrades announced earlier this year.
The HBS Premier IA WAAS upgrade offers operational flexibility and cost savings associated with direct and curved area navigation (RNAV) routes.WAAS RNAV offers improved access to special use airspace, high traffic and/or terrain challenged airports.
There are currently more than 2300 LPV approaches certified and in use today. WAAS LPV approaches provide decision heights as low as 200 feet with one half mile visibility .The result is improved safety and cost savings associated with the reduction of missed approaches and flights to alternate airports.
WAAS upgrades for the Premier I, Hawker 400XP /Beech craft 400A and early model Hawker 800XP aircraft equipped with Honeywell flight management systems are currently in process.
Twin Commander Enthusiastic
Twin Commander LLC is pleased with the response to its Airport fest display at AOPA Aviation Summit. "The annual AOPA conference is a great way to meet owner-pilots who are interested in performance aircraft," noted Twin Commander president, Matt Isley,"and this years event did not disappoint .The crowds were large and enthusiastic and we saw steady traffic all three days," he said.
"We've found that a lot of customers who are looking for an aircraft that has 300-knot cruise speed capability and a proven and tested airframe, are selecting the Twin Commander," noted Aero Airs Richard Urban, a long-time customer.
Twin Commanders Airport fest display featured a recently refurbished 690B Twin Commander owned and operated by Aero Air.
The immaculate 690B featured upgrade Honeywell TPE3311-10T engines, a sate-of-the –art Garmin panel with G600 electronic flat-panel flight and multi-function displays and GNS530 and 430 WAAS-capable flight management systems ,a new paint and interior.
