Simulation of free piston linear engine motion with different intake and exhaust port positions
This paper presents the simulation of two-stroke free piston linear engine motion consisting of combustion and air-kickback chambers. Dynamic and gas-dynamic models for slider-piston motion are presented. The influence of the intake and exhaust port position on the engine performance is explored....

Summary: | This paper presents the simulation of two-stroke free piston linear engine motion consisting of
combustion and air-kickback chambers. Dynamic and gas-dynamic models for slider-piston motion are
presented. The influence of the intake and exhaust port position on the engine performance is explored.
Using chosen variables, the motion of two-stroke free piston linear engine is successfully simulated. It
shows that the velocity profile of slider-piston motion is far from sinusoidal. The comparison between
both simulations with different location of intake and exhaust port reveals that the slider-piston velocities
are not similar. Slider-piston velocity of model 2 with intake and exhaust port at the top of the cylinder
block is 19 % higher than model 1 (intake and exhaust port at the cylindrical-side of cylinder block).
Although that was the case, model 1 has an advantage in a way that it does not need valves and openclose
valves system |
