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 is difference between valve and port?
valves are use in four stroke engine, and ports are use in two stroke engine.
How can YOU identify a two stroke or four stroke engine by seeing it?
if you see the difference between valves
How do you distinguish between a petrol engine and diesel engine?
A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition. Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.
Can you convert a gas engine into a diesel?
It would definitely not be possible to convert a gas engine into a diesel engine because the cylinder block and head would not be strong enough. A diesel engine needs a much higher compression ratio than a gas engine, which means the gas engine's cylinder block and cylinder head would probably explode under the higher pressure. You would have to change so many things: * the crankshaft, to get a longer piston stroke, because the compression ratio for gas is much lower than for diesel; * the connecting rods and pistons * the cylinder head and camshaft to get the right valves and holes for diesel fuel injectors instead of spark plugs * the fuel injectors and fuel pump - and maybe the tank too, to get the right vents and filler cap for diesel instead of gas * the exhaust system to get the right catalytic converter for diesel * the gears in the gearbox to get the right gear ratios to suit a diesel engine * diesel does not use any spark plugs so you would have be sure to use a safe method to disable the high voltage ignition system (which supplies sparks for gas ignition) and replace it by the right kind of electronic engine management unit to control the diesel fuel injectors * etc. In short, it would not make sense to try to do it from a cost point of view. You could perhaps buy a reconditioned diesel engine made to go in the same model of car, but, unless you could fit it yourself along with all the other bits and pieces, it would be far cheaper just to buy a secondhand diesel model of your vehicle and sell your present gas model.
What is the purpose of camshaft in the diesel engine?

If the air intahe and exhaust valves were not actuated what damages expected with the diesel engine?
If the air intahe and exhaust valves were not actuated what damages expected with the diesel engine? The engine is a four stroke marine diesel engine and because of the rocker arm gears broken the valves remained closed and not actuated.
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 .
How many valves in b2500 diesel engine?
12
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 .
How can YOU identify a two stroke or four stroke engine by seeing it?
if you see the difference between valves
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
Most cars have a four-stroke engine with four or more what?
Valves
Does a two stroke engine have only one valve per cylinder?
Some two stroke engines have 4 valves, Detroit Diesel 71 series and 53 series engines for example. Most small 2 stroke engines have no "Valves" at all in the sense of the "POP" valve used in four stroke engines. Some people feel these engine has one valve because the piston acts as the valve covering the ports cut into the cylinder walls.
