.Usage: Turn on the power and slowly turn the handle in the direction indicated by the arrow
.Suction stroke: The intake valve is opened, the exhaust valve is closed, and the piston moves downward from the top dead center to the bottom dead center.A mixture of fuel and air enters the cylinder from the intake manifold
.Compression stroke: The intake valve and the exhaust valve are closed, the piston moves from bottom to top,and the fuel mixture is compressed in the cylinder, and the temperature rises rapidly
.Power stroke: When the piston reaches the top dead center, the spark plug is ignited (represented by the bulb at the spark plug)
.The fuel mixture is spotted (the bulb is extinguished to indicate that the ignition is complete). The gas in the cylinder expands rapidly due to being ignited, pushing the piston to start moving downward to the bottom dead center. At this time, the crankshaft outputs power
.Exhaust stroke: Due to the inertia of the rotating mechanism, the crankshaft passes the bottom dead center and the piston moves upward
.At the same time, the exhaust valve is opened and the exhaust gas is discharged from the exhaust pipe.After the exhaust stroke is completed, the exhaust valve is closed, the intake valve is opened, the piston moves downward, a new suction stroke is started, and the next cycle is entered
