In a diesel engine, air is compressed to roughly 1/15 to 1/20 of its usual volume just before the diesel fuel is injected, or pumped, into the engine. The fuel-air mixture becomes hot enough to burn, driving expansion of the cylinder (piston) in the engine. Just as during the air-compression phase, there is no heat transferred into or out of the engine; that occurs only during the exhaust phase. The fuel injection system in a diesel engine consists of an injection pump, a fuel line and a nozzle (also called an injector). When the air is compressed, the pressure inside the cylinder briefly rises to 400 to 600 pounds per square inch (normal atmospheric pressure is less than 15 psi), driving internal temperatures into the range of 800 degrees Fahrenheit to 1,200 F (430 degrees Celsius to 650 C).

A diesel injection pump for sale engine features the same cycles and physical arrangement as a gasoline engine; it is the process of ignition, not the structure that sets them apart. In general, they are more reliable, generate more power per kilogram of fuel and are more efficient overall; diesel fuel also poses less of a fire hazard.

The diesel engine of Nozzle Masters – Diesel Injection Specialist undergoes a four-step cycle to complete one compression-expansion movement of a piston. The first of these is the air-compression step; because the same amount of heat is kept in a rapidly shrinking space, it drives up pressure and temperature. In the second (ignition) phase, pressure remains constant as volume begins to expand.

During the third phase of the Caterpillar fuel injection pump, called the power stroke, the volume and pressure both decrease as the engine does work, ultimately powering the car. Finally, in the exhaust phase, the volume remains constant at its highest level, and then the cycle begins anew when air is drawn in for compression in the first phase.
