fly wheel

It saves the power in other strokes. The fly wheel is a heavy steel wheel attached to the rear end of crankshaft. the engine delivers power during power stroke.The engine tends up to speed up. The other stoke are dead strokes where they absord power. The flywheel absorbs the energy in power stroke due to inertia and delivers the energy in dead strokes.. thus the fly wheel keeps the engine at constant ratio 

single cylinder and multicylinder engine

Power output is more uniform in case of multicylinder engines due to increase in frequency of power impulses with the increase in the number of cylinders. As number of cylinders increases, torstional, vibration.

hydraulic accumulator

a hydraulic accumulator is a device which is used in fluid power circuits to stroke fluid under pressure.
