What is the least number of valves required at the top of a four-stroke cycle engine?
two
Least number of valves required at the top of a four-stroke cycle engine?
Two. Intake, and exhaust.
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
Is 1997 90HP mercury outboard engine a 2 cycle or 4 stroke?
generally speaking if it has valves its a 4 stroke 4 cycle engine......if it doesnt have valves then it is a two stroke 2 cycle...................
How do you adjust valves on a 2004 polaris sportsman 400?
There is no valves as it is a 2-stroke engine .
What is difference between valve and port?
valves are use in four stroke engine, and ports are use in two stroke engine.
Why deflected shape of piston in 2 stroke engine?
In a 2 stroke engine the piston itself is the intake/exhaust valve, instead of having separate valves as in the 4 stroke. The odd shape of the piston is the location of these valves.

What opens the valves?
the valves are connected with the cams on the engine , the cams are rotated during the power stroke .
What are the names of the strokes on a two stroke engine?
A two-stroke engine is an internal combustion engine that completes the process cycle in one revolution of the crankshaft (an up stroke and a down stroke of the piston, compared to twice that number for a four-stroke engine). This is accomplished by using the beginning of the compression stroke and the end of the combustion stroke to perform simultaneously the intake and exhaust (or scavenging) functions. In this way, two-stroke engines often provide strikingly high specific power, at least in a narrow range of rotational speeds. The functions of some or all of the valves required by a four-stroke engine are usually served in a two-stroke engine by ports that are opened and closed by the motion of the pistons, greatly reducing the number of moving parts.
How can YOU identify a two stroke or four stroke engine by seeing it?
if you see the difference between valves
Most cars have a four-stroke engine with four or more what?
Valves
