## How a Car Engine Works: 3D Animation Video
Introduction
A car engine is a complex machine that converts the chemical energy of gasoline into mechanical energy that powers the wheels. This process is accomplished through a series of four strokes: intake, compression, power, and exhaust.
Intake Stroke
The intake stroke begins when the piston moves down the cylinder, creating a vacuum that draws air and fuel into the cylinder through the intake valve. The intake valve then closes, sealing the cylinder.
Compression Stroke
The piston then moves up the cylinder, compressing the air and fuel mixture. This compression increases the temperature and pressure of the mixture, making it more combustible.
Power Stroke
When the piston reaches the top of the cylinder, the spark plug ignites the air and fuel mixture. The burning mixture expands rapidly, driving the piston back down the cylinder. This expansion creates the power that turns the crankshaft.
Exhaust Stroke
The exhaust stroke begins when the exhaust valve opens, allowing the burned gases to escape from the cylinder. The piston then moves up the cylinder, pushing the burned gases out through the exhaust valve. The exhaust valve then closes, sealing the cylinder.
The Four-Stroke Cycle
The four strokes of the engine are repeated over and over again, creating a continuous cycle of power. The crankshaft converts the up-and-down motion of the piston into rotary motion, which is then transmitted to the wheels.
