Four stroke engine is an engine which produces a power to require four process steps up and down the piston, two rotations of the crankshaft, and one round Noken (camshaft).
4 The process is divided into cycles:

1. Step Suction
Aiming to enter mist air - fuel into the cylinder. As the engine power produced depends on the amount of fuel burned during the combustion process.
The process is;
- The piston moves from top dead point (TDC) to Bottom Dead Point (TMB).
- Inlet valve opens, fuel into the cylinder.
- Kruk As rotates 180 degrees.
- Noken As rotates 90 degrees.
- Negative pressure piston-air mist suck fuel into the cylinder.

2. Step Compression
It starts when the inlet valve closes and the piston pushed toward the engine due to the momentum of the crankshaft and flywheel.Tujuan of the compression stroke is to raise the temperature so that the air-fuel mixture can be mixed. The compression ratio will also closely related to power production
The process is as follows:
- The piston moves back from TMB to the TMA
- Valves In closing, Ex valve remains closed
- Fuel dome is constricted into a burning (combustion chamber)
- About 15 degrees before TDC, the spark plug began to ignite sparks and start the burning process
- Kruk as achieving one full rotation (360 degrees)
- Noken axles reach 180 degrees

3. Step Power
It starts when the air / fuel ignited by a spark plug. Quickly mix the burning vines and there was an explosion that is held back by walls of the cylinder head, causing a kick behind the high pressure pushes the piston down the cylinder bore. Linear motion of the piston is converted into rotational motion by the crankshaft. The rotational energy of the flywheel is forwarded as momentum towards which not only generate power, counter balance weight on the crankshaft helps pistons do next cycle
The process is as follows:
- The explosion created completely in the combustion chamber
- Piston thrown from the TMA to the TMB
- Inlet valve closes fully, while towards the end of the business step exhaust valves begin to open slightly
- There was a transformation of energy back and forth motion of the piston into rotational energy of the crankshaft
- Round Kruk As reaches 540 degrees
- Round Noken As 270 degrees

4. Step Remove
Step waste is crucial to generate operating performance and efficient machine tender. The piston moves from the combustion gas pushed out of the cylinder to the exhaust pipe. This process must be done with total, because there is little residual combustion gases are mixed together with new gas intake will reduce the potential power generated
The process is:
- Counter balance weight on the crankshaft to provide normal force to drive the piston from BDC to TDC
- Ex valve open Perfect, fully closing the valve Inlet
- Gas residual combustion products pushed out by the piston through the exhaust port to the exhaust
- Kruk as did two full rotations (720 degrees)
- Noken as completing one full rotation (360 degrees)

FINISHING IMPORTANT - overlapping
Overlap is a condition in which both the intake valve and out are within possisi slightly open at the end of the exhaust step up to the initial step suction
Serves for the performance efficiency of the internal combustion engine. Their mechanical performance barriers of inertia valve and the air in the manifold, it is necessary to begin to open the entrance valve before the piston reaches TDC at the end of the exhaust step to prepare the suction step. With the aim to eliminate all residual gas combustion, exhaust valves remain open until after TDC. The degree of overlapping depends on the design of the machine and how fast this machine to work
the benefits of overlapping processes:
- As the flushing of the combustion chamber, pistons, cylinders from the remnants of burning
- Cooling temperature in the combustion chamber
- Helps exhasut scavanging (flue gas discharge)
- Maximize the intake process fuel
