Automobile (basic)
This document attempts to describe everyday use of an automobile. The class of automobile considered is an average performance, front-wheel drive consumer vehicle.
The accelerator, also known as the gas pedal controls the engine output. Pressing the accelerator increases the revolutions of the engine, mainly by allowing more air to enter the combustion chambers, or the cylinders, per revolution. The revolutions for various stages in this section depend on the engine, and every engine has a unique set of values. The tachometergives the value of engine speed at any time. However, an experienced driver is supposed to know the speed of the engine without taking eyes off the road. When the car is first started, the engine moves at a speed called the idle speed. Many consumer cars provide means of changing the idle speed of the engine.
