What is the purpose of the inlet exhaust valve?
there is no such thing as an inlet exhause valve, you have the inlet valve which lets your air/fuel mixture enter the engine for the power stroke and the exhaust valve which allows the burnt out air/fuel mixture to leave the engine after that the inlet valve re-opens and lets fresh or new air/fuel mixture enter to let it be compressed and combust for the power stroke. First, the correct name is "Intake" valve. There are intake, intermediate intake and exhaust valves in some newer foreign made engines.
Why is the exhaust valve seat is made wider than the inlet valve seat?
Better heat distribution. The exhaust valve sees a lot more heat.
Are the inlet valves made of the same material as exhaust valves or have different treatmnet?
Most intake valves are made of the same material as the exhaust. They are heat resistant treated high carbon steel, as are the valve seats. The exhaust valve is usually larger in diameter to aid in scavenging of the spent hot exhaust gas. Some more expensive engines have sodium (Na) filled exhaust valves to aid heat transfer to the valve seat to help cool the valve.
What is the value of inlet exhaust valve spring design in 4 stroke 2 wheeler?
This design allows more power to be made available for the 4 stroke 2 wheeler. Multi-valve engines allow the more higher RPM's to be achieved, thus resulting in more power being made.
Why do intake valves wear and exhaust valves do not This is a Honda CRF250r?
dirt into engine is a big problem and the intake are made softer material due to less heat on valve faces
Why are intake and exhaust valves different materials?
The exhaust valve runs much hotter than the intake valve, so it has to be made out of a more durable(and more expensive) material. The intake valve can get by with a simpler and less expensive material.
What is exhaust valve mainly cooled by?
The exhaust valve doesn't get any cooling except to say that there is some cooling effect when the new charge of air/fuel mixture enters the chamber. That's why exhaust valves are extra-thick, and sometimes made from more heat-resistant material such as stainless steel or titanium.
Why are valve clearances different on each valve?
Intake valves run cooler than exhaust valves and they are made of different material, so their thermal expansion is less than the exhaust valves. Therefore, they can have a smaller valve lash clearance, since they won't 'grow' as much due to thermal expansion, and won't present the problem of slamming into the top of the piston as readily as exhaust valves with too-small valve lash clearances will. But, not all engines have dissimilar valve lash clearances on intake and exhaust. Many small single-cylinder engines have exactly the same clearance on both intake and exhaust valves.
What does a car's exhaust system do?
When the internal combustion happens inside the engines cylinders, a "by product" is made. This is called exhaust. An exhaust system takes that from the engine out the back of the car through metal piping.
Does the 1983 Renault 5 non turbo engine 1.4l have the same exhaust gasket as the turbo model?
No, it is different because the Renault 5 gt turbo was made for the exhaust fumes to run through the turbo creating boost. On a non turbo version the piping will be made simply to leave the engine directly out of the exhaust.
When was the first overhead valve 6-cylinder engine made?
The original overhead valve or OHV piston engine was developed by the Scottish-American David Dunbar Buick around 1902.
How do you change the stock single exhaust to dual on a 1994 43L Caprice?
Use an exhaust made for an LT1 engine the blocks are identical it is the insides that is different. Will bolt right on.
