Why does a car go faster when the accelerator gets pushed?

When the accelerator pedal is pushed, it opens the throttle valve of the engine, allowing more air and fuel to enter the cylinders. This increases the pressure inside the cylinders, which pushes the pistons down with greater force. This increased force causes the crankshaft to rotate faster, which in turn increases the speed of the car.

In addition, when the accelerator pedal is pushed, it also increases the amount of fuel that is injected into the cylinders. This additional fuel helps to create a more powerful explosion, which further increases the pressure inside the cylinders and causes the car to accelerate even faster.

The amount of acceleration that is achieved when the accelerator pedal is pushed depends on a number of factors, including the engine size, the weight of the car, and the gear that the car is in. A larger engine will produce more power and cause the car to accelerate more quickly, while a heavier car will require more power to accelerate at the same rate as a lighter car. Additionally, the car will accelerate more quickly in a lower gear than in a higher gear.
