How a Car Engine Works

A car engine is a complex machine that converts the chemical energy in gasoline into mechanical energy that can be used to power the car. The basic principle behind how a car engine works is that it uses a series of explosions to push pistons up and down, which in turn rotates a crankshaft. This crankshaft rotation is then used to power the car’s wheels.

The Four Strokes of an Engine

The four strokes of an engine are the four main steps that occur in each cylinder of an engine. These four strokes are:

1. Intake stroke: The intake valve opens and the piston moves down the cylinder, drawing in a mixture of air and gasoline.
2. Compression stroke: The intake valve closes and the piston moves back up the cylinder, compressing the air and gasoline mixture.
3. Power stroke: The spark plug ignites the air and gasoline mixture, creating an explosion that forces the piston down the cylinder.
4. Exhaust stroke: The exhaust valve opens and the piston moves back up the cylinder, pushing the exhaust gases out of the cylinder.

The Parts of an Engine

An engine consists of many different parts, including:

• Cylinders: The cylinders are the chambers in which the pistons move up and down.
• Pistons: The pistons are the cylindrical-shaped pieces that move up and down inside the cylinders.
• Crankshaft: The crankshaft is the shaft that rotates as the pistons move up and down.
• Valves: The valves open and close to let air and gasoline into the cylinders and to let exhaust gases out of the cylinders.
• Spark plugs: The spark plugs ignite the air and gasoline mixture in the cylinders.

The crankshaft is connected to the wheels of the car through a series of gears. As the crankshaft rotates, it turns the gears, which in turn turn the wheels.
