Is it Better to Buy Diesel Genset or Gasoline Generator

Many clients ask us “ is diesel generator better or gas generator?”, we think diesel generator is better than gas generator. Today we will analyze and summarize for you.

In the current economic situation, fuel prices continue to rise, you should choose a cost-effective fuel that meets your needs. The internal combustion engine is highly efficient and cost-effective. Although the price of diesel is higher than that of gasoline, the energy density of diesel is higher. Compared with the same volume of gasoline, energy density can extract more energy from diesel. Most cars, such as trucks, cars, etc., prefer diesel because of their long driving range. Diesel is heavier than gasoline, is more fuel efficient, and has a higher boiling point.

The internal combustion engine works by compression ignition, while the internal combustion engine works by spark ignition. When using a diesel generator, air is drawn into the engine, generating a higher compression rate, which heats the engine. The engine temperature rises, which is much higher than the temperature that a gasoline engine can reach. Under high temperature and high pressure conditions, diesel fuel enters the engine and burns due to extreme temperatures. At each stage, air and fuel are injected into the diesel generator, and at the same time a mixture of air and gas is introduced into the gas generator. In internal combustion engines, fuel is injected by injectors, and gasoline engines are injected with carburetor. A gasoline engine sends fuel and air into the engine together and then compresses it. Diesel engines can only compress air, and the ratio is higher. The compression ratio of diesel engines is 14:1 to 25:1, while the compression ratio of gasoline is 8:1 to 12:1. Diesel generators can be divided into two or four wheels, and choose according to the operating mode. A water-cooled generator is much better because it is quiet and temperature controllable.

Advantages of diesel generators:

Diesel generators are more efficient and more efficient than gasoline generators. Part of the reason is:

1. Early models of diesel generators have higher noise and higher maintenance costs. But modern diesel generators require less maintenance than gasoline generators and are less noisy.

2. Diesel generators are more powerful and more reliable.

3. The fuel price per kilowatt of diesel generators is 30% to 50% lower than that of gas engines.

4. There is no spark when the fuel spontaneously ignites. No spark plugs or spark lines reduce maintenance costs.

5. The diesel engine with a 1800rpm water-cooled engine can run for 12,000 to 30,000 hours before any major maintenance.

6. Gasoline burns hotter than diesel, so it has a shorter service life compared to diesel devices.

7. Wide application range. The diesel generator has a large volume, and the power can reach 8-2000kw, which is suitable for large-scale public places or industrial places. The power range of gasoline generators is between 0.5-10kw, and the equipment itself is relatively small and more suitable for household use.
