The main difference between gasoline generator and diesel generator


1. Type of ignition: The mixed gas in the diesel engine is ignited by compressed heat. The mixture of fuel and air in the cylinder of a gasoline engine is ignited by a spark plug.


2. Types of fuel: Diesel is less volatile than gasoline, but diesel has a larger calorific value per gallon. Therefore, 5dm3 diesel can get more power than 5dm3 gasoline.


3. Mixing of fuel and air: In a diesel engine, the mixing of diesel and air is carried out after the diesel is injected into the cylinder. In a gasoline engine, fuel and air are mixed in the carburetor and intake duct.


Because the mixing must be immediately after the fuel injection, the diesel generator has a specially designed combustion chamber, which is conducive to the mixing of diesel and air. Therefore, the design and manufacture of the combustion chamber are very important for diesel generators.


The big difference between a diesel generator and a gasoline generator is the ignition device and the fuel system. A diesel generator is a compression-ignition internal combustion engine, which uses a fuel injection pump and several fuel injectors; while a gasoline generator has a carburetor, a distributor, and several spark plugs.


There are many similarities between diesel generators and gasoline generators. The appearance of diesel generators is almost the same as that of gasoline generators. The internal components of diesel generators are also similar to those of gasoline generators, but most of the internal components of diesel generators are stronger and heavier than gasoline generators. This is because diesel generators have to withstand greater internal pressure. The operation of a diesel generator is the same as a gasoline engine, depending on air, fuel, and ignition.
