What is Exhaust and intake valve?
As an air/fuel mixture is drawn into the intake ports, intake valves open to allow the mixture to enter the cylinder. On the exhaust stroke of an engine, the exhaust valves open, allowing the burned air/fuel mixture to exit out the exhaust ports. Intake valves are larger than exhaust valves, and are able to be found on the "cold" or intake side of the cylinder head(s).
What is the intake manifold and exhaust manifold for a 1998 Ford Escort?
Intake manifold delivers the fuel air mixture to the cylinder heads, exhaust manifold collects the gases after combustion, and channels them into the exhaust pipe.
What is the intake and exhaust valve purpous?
The fuel/air mixture passes through the intake valve to get into the combustion chamber. After combustion, the spent gasses travel out of the combustion chamber through the exhaust valve.
What correctly describes the position of the intake and exhaust valves during most of the power stage in a four cycle gas engine?
closedUpdated answer,Firstly the four stages of an "Otto Cycle Engine" are, Induction the intake valve is opening, to let fuel and air mixture into piston chamber. Compression the intake valve and exhaust are shut to compress fuel air mixture. Powerfuel air mixture ignited, both the intake and the exhaust valves are closed. And finally Exhaust when the exhaust valve is open to release spent gasses. At idle speed approximately 800 rpm it should be appreciated timing is important.
What are the functions ofengine inlet and exhaust manifolds?
Inlet manifolds are actually called intake manifold and this is to allow air to be injected into the fuel for either a rich or lean mixture for either performance or gas mileage (which can be adjusted). The Exhaust manifold is used to expel your burnt fuel, or air/fuel mixture, during the exhaust stroke on a 4-cycle engine to allow room for the intake stroke to bring in your fuel, or air/fuel mixture. The exhaust manifold simply directs the exhaust and become extremely hot. The exhaust is pushed out by the exhaust stroke.
Which is intake and exhaust?
Your exhaust lines up with exhaust pipes ,your intake lines up with your intake runners.
How do you find the intake and exhaust lifters on a engine?
The exhaust lifters will line up with the exhaust manifolds,Remove the valve cover if your working on a V8 and the valve that lines up with the exhaust port will be the exhaust valve,If it is a Chevy V8 they will be from standing in front of the car exhaust,intake,intake,exhaust,exhaust,intake,intake,exhaust.
Which valve is exhaust and which valve is intake on 94 GM 350ci?
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
What describes the position of intake and exhaust valves during the most powerful stage in a four-cycle gas engine?
-intake: exhaust closed, intake open -compression: exhaust closed, intake closed -combustion: exhaust closed, intake closed -exhaust: exhaust open, intake closed
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.
Exhaust valve smaller or bigger than intake valve in a turbo charged engine?
the exhaust valve will always be smaller as the piston is forcing the combusted gases out. The intake valves have to be bigger as the piston is only drawing the mixture in through sucktion.
Which valves are the intake and exhaust on a 20r engine?
the intake are next to the carb and the exhaust are next to the exhaust manafold intake are .008 exhaust are .012 with the engine warm good luck
