Can side cam engine be installed in 4 stroke or 2 stroke engine?
sidecam engine cannot be installed in 2 stroke engine because in 2 stroke engine we have inlet & exhaust ports not valves... so when piston moves up and down it automatically opens the inlet and exhaust ports so it does not require any camshaft for opening of valves as it is required in 4 stroke engine
Moving parts of a two stroke engine compared to a four stroke?
Two strokePistonConnecting RodCrankshaftFour strokePistonConnecting RodCrankshaftCamshaftCam follower (inlet and exhaust)Rocker (inlet and exhaust)Valve (inlet and exhaust)Cam drive (belt or gear)Typically a two-stroke is air cooled, while a four-stroke is water cooled, so the water cooling adds these additional items:Water pumpFanFan / pump drive (typically belt)
What is valve overlap?
Valve overlap occurs in a four-stroke engine at the end of the Exhaust stroke and at the beginning of the Induction stroke; and is when both the exhaust and inlet valves are open at the same time. At the end of the Exhaust stroke, the Exhaust valve is closing and the Inlet valve is starting to open in preparation for the induction of fuel and air into the cylinder. It is common knowledge that in vehicles that cannot alter the valve timing, the Inlet valve opens approx 6 degrees before top-dead-centre and the Exhaust valve closes at 9 degrees after top-dead-centre

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.
What is the purpose of camshaft in the diesel engine?
The camshaft operated the inlet and outlet valves in the cylinder to admit fuel to the engine before ignition and expel the exhaust gas after the power stroke. The camshaft operates at half the crankshaft speed in a four-stroke engine.
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.
How do you tell if a 49cc engines is a 2 stroke or a 4 stroke for a pocket rocket?
It should be a 2 stroke .Ans. 2A 2 stroke engine has a transfer port from the bottom of the cylinder to about half-way up it; it has no valves.A 4 stroke engine has no transfer port, but has inlet and exhaust valves, with their associated valve gear.
How many cam in 4 stroke engine?
for SI engine 2 cams will be provided......,for CI engine 3 cams PROVIDED for opening of inlet,exhaust valves and operating of fuel injector...ok got it
How do you set the tappets on a Mitsubishi 6d14 engine?
With No1 cylinder at TDC adjust the following valve clearances, No. 1, inlet and exhaust No. 2, inlet No. 3, exhaust No. 4, inlet No. 5, exhaust Then turn the crankshaft 1 full turn so that No 6 cylinder is at TDC and adjust the following valve clearances, No2. , exhaust No. 3, inlet No. 4, exhaust No. 5, inlet No. 6 inlet and exhaust. Both inlet and exhaust clearances ar 0.4 mm with engine cold. This info is from the original service manual
What are the valve clearances for a 1.2 8v Renault clio?
D7F engine: Inlet: 0.10mm Exhaust: 0.20mm E7F engine: Inlet 0.10mm Exhaust 0.25mm Clearences are when cold,
What is a inlet valve and exhaust engine made from?
metal (steel)
