Inside the cylinder, clean air-having passed through an air filter-mixes thoroughly with high-pressure atomized diesel fuel injected by the fuel injector. As the piston moves upward, the mixture is compressed; its volume decreases and its temperature rises rapidly, reaching the diesel fuel's ignition point. The diesel ignites, causing the mixture to burn violently and expand rapidly, which drives the piston downward-a process known as the "power stroke." The cylinders perform this power stroke sequentially in a specific order; the thrust exerted on the pistons is transmitted through connecting rods into force that turns the crankshaft, thereby driving its rotation. By mounting a brushless synchronous AC generator coaxially with the diesel engine's crankshaft, the engine's rotation drives the generator's rotor. Based on the principle of electromagnetic induction, the generator produces an induced electromotive force, generating an electric current when connected to a closed load circuit.
This description covers only the fundamental operating principles of the generator set. Achieving a usable and stable power output requires additional components and circuits for control and protection.
