Scope of Application and Basic Principles of Diesel Generator Sets

Scope of Application

Diesel generator sets are widely used for long-term (or temporary) power supply in small and medium-sized enterprises, including industrial, commercial, educational, and medical facilities; they are also used in various fixed power sources such as generator sets, construction machinery, and ships.

Basic Principle

Inside the cylinders of a diesel engine, clean air filtered through an air filter is thoroughly mixed with high-pressure atomized diesel fuel injected by the fuel injector. As the piston moves upward, the volume decreases and the temperature rises, reaching the ignition point of the diesel fuel. The diesel ignites, causing the mixture to burn vigorously. The resulting rapid expansion of the mixture pushes the piston downward; this is known as the power stroke. Each cylinder operates in a specific sequence, and the thrust acting on the piston is converted via the connecting rod into a force that drives the crankshaft to rotate.
