Diesel Generators
A diesel engine drives the generator, converting the energy of the diesel fuel into electrical energy.
Inside the diesel engine cylinder, clean air (filtered by the air cleaner) mixes thoroughly with high-pressure atomized diesel fuel injected by the nozzle. As the piston moves upward, the mixture is compressed; its volume decreases and its temperature rises rapidly, reaching the fuel's ignition point. The diesel ignites, and the mixture burns violently, causing rapid volumetric expansion that drives the piston downward-a process known as the "power stroke" (or "doing work").
Gasoline Generators
A gasoline engine drives the generator, converting the energy of the gasoline into electrical energy.
Inside the gasoline engine cylinder, the fuel-air mixture burns violently, causing rapid volumetric expansion that drives the piston downward to perform work.
In both diesel and gasoline generators, the cylinders perform work sequentially in a specific order. The thrust exerted on the pistons is transmitted through connecting rods to the crankshaft, driving its rotation. By coaxially mounting a brushless synchronous AC generator to the 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.
