Displacement is a measurement of the total volume of an engine, usually expressed in liters or cubic centimeters. For example, a 1,000cc power plant could be described as a 1.0-liter engine. Similarly, a 1,320cc engine would be a 1.3-liter engine.
In the automotive industry, engine displacement is measured in cubic inches. For example, the fifth-generation Ford Mustang used a 302 in3 engine. That makes a 28L or 35L engine displacement 302 in3 or 280 cubic inches. A 28L or 35L engine’s displacement equals its cylinder capacity times the piston diameter.
A pressure switch is triggered when the primary pressure line reaches a certain threshold. This actuates a motor 25 that moves a cam-disc in a clockwise direction. As the pushrod moves to the right, it displaces the fluid in the space between the right piston chamber 58R and the inner wall 66R of the cylinder.
The maximum amount of gasoline the engine can burn
Gasoline is generally a blend of combustible hydrocarbons. The octane rating measures its quality. It is calculated by examining the proportions of two compounds found in gasoline. These compounds are iso-octane and regular heptane, and the higher the octane, the better the fuel quality.
