How Do Engines Push Cars?

When you press the gas pedal in your car, you’re sending a signal to the engine to increase its power output. The engine then uses this power to turn the wheels, which pushes the car forward.

But how does the engine actually create this power? It all starts with the combustion of fuel.

The Combustion Process

When you turn the key in your ignition, you’re sending a signal to the starter motor, which turns the engine over. This causes the pistons in the engine to move up and down, creating a vacuum that draws air and fuel into the cylinders.

Once the cylinders are filled with air and fuel, the spark plugs ignite the mixture, creating a small explosion. This explosion forces the pistons down, which in turn turns the crankshaft.

The crankshaft is connected to the transmission, which then turns the wheels. This is how the engine’s power is transferred to the wheels, which pushes the car forward.

The Role of the Transmission

The transmission is a key part of the engine’s power delivery system. It allows the engine to operate at different speeds and torques, which is necessary for driving in different conditions.

For example, when you’re driving at a low speed, the transmission will use a low gear ratio, which multiplies the engine’s torque. This gives the car more power to accelerate. When you’re driving at a high speed, the transmission will use a high gear ratio, which reduces the engine’s torque but increases its speed.
