Basic 4-stroke and 2-stroke engine operating cycle

4-stroke engine cycle consists of stroke Entry, compression stroke, power stroke and exhaust stroke

intake stroke

CASH movement of the piston to the KBS.

                        Inlet valve is open.

           Ekzoz valve closed.

           Air fuel mixture sucked.

Read phonetically

compression stroke

Piston movement of the KBS to CASH.

           Inlet valve is closed.

           Ekzoz valve closed.

           Air fuel mixture is compressed.


power stroke

Both valves are closed

           Plug penyucuh produce fireworks

           Fuel air mixture burns

           Piston less strongly than the KBS CASH


ezkos stroke

The exhaust valve opens.

           Inlet valve is closed.

           The piston moves from the KBS to CASH.

           Combustible gas that pushed out.

Basic 2-stroke engine operating cycle

o    Applicable air fuel input in the box shaky because of volume expansion of the roll boxes, and pore in the open.
o There was a compression in the cylinder space above the piston as the volume decreases.
o When the piston up to the plug CASH penyucuh fireworks and burn out the fuel mixture is compressed in place earlier, and POWER valid
o The crankcase compression occurs because the volume of the crank chamber decreases.
o All ports closed
o When the piston reached the open exhaust port KBS, the exhaust already happened. At the same time accepted the transfer port is also open air and the fuel input itself into the cylinder crankcase.
