The difference between diesel generators and gasoline generators

The main differences between diesel generators and gasoline generators are the type of fuel, ignition method, output power, compression ratio, place of use, economic performance, and emission performance.

Fuel Type: The fuel for a diesel generator is diesel, whereas the fuel for a gasoline generator is gasoline. Diesel is less volatile and has a larger calorific value per liter of diesel, which makes diesel generators more compact than gasoline generators while providing the same power.

Ignition method: The ignition of a gasoline generator is done through a spark plug, which is a type of ignition type internal combustion engine. In contrast, the ignition of a diesel generator is to ignite the fuel by the heat generated by compressed air, which is a type of compression-ignition internal combustion engine.

Power output: Diesel generators typically have a much greater power output than gasoline generators. For example, the high power of the general gasoline generator set is only 10KW, while the small power of the diesel generator set is 8KW, and the high power can reach 2000KW.

Compression ratio: The compression ratio of the diesel engine is greater than that of the gasoline engine, which leads to a higher thermal effect of the diesel engine, which makes the fuel consumption of the diesel engine lower than that of the gasoline engine.

Where to use: Gasoline generators are generally used in low-power applications such as home lighting and air conditioning. Diesel generators are mainly used as the main and standby power supply for hotels, breeding enterprises, chemical enterprises, etc., as well as high-power industries, factories, hospitals, hotels, governments, real estate, etc.

Economic performance and emission performance: The economic performance and emission performance of diesel generators are generally better than those of gasoline generators. This is because diesel has a higher thermal efficiency than gasoline, and the volume of combustion of the same mass releases more energy, and diesel is not easily volatile, which makes diesel generators more economical and environmentally friendly in long-term operation.

To sum up, diesel generators and gasoline generators have their own characteristics and application scenarios. The type of generator you choose depends on the specific application needs, such as the amount of power required, the environment in which it is used, the economy and the environmental requirements.
