exhaust gases are generally removed from the cylinders of a two stroke/cycle diesel engine by?

Answer 1

A compression stroke of the piston forces the exhaust gas out through an exhaust port.

Answer 2

At the end of the (downward) power stroke, the piston uncovers an exhaust valve in the bottom of the cylinder and , the higher pressure combustion gases are simply vented to atmosphere. (There's no actual exhaust stroke to push them out).

(Irv S, your explanation is for a 2-stroke petrol (gasoline) engine which uses a spark plug and has a cylinder with a larger volume lower section where the compression of the fuel/air mixture takes place).

Answer 3

In a Detroit Deisel engine-- the 53, 71 and 92 series (the old engines) the exhaust valves open just as the piston passes the port belt on the way down- ending the power stroke- the higher pressure in the air box forces the exhaust gasses out and recharges the cylinder with fresh air- as the piston reachest the top of the port belt- the valves close and the compression begins- fuel is injected just prior to TDC (top- dead center) - the compression pressure has generated a high enough temperature to burn the fuel-- the power srtoke begins.. yadda yadda yadda..

Answer 4

its pretty simple.for practical there is no other way to store exhaust gases in the engine only u need to throw them out.but if u r thinking use in as a cycle mean exaust gases again go to inlet.that what a true diesel cycle.but practially in diesel engine it a somewhat mechanical cycle.the exhaust gases dont have O2.so it can't be burn again.so
its batter we take some fresh air and burn it
rather then use exhause air only

Answer 5

The residual pressure of the end of the
expansion phase and displacement by
the incoming new charge.

Answer 6

through exhaust valve

Answer 7

valves releasing the pressure
