Generator sets are divided into gasoline generators and diesel generators according to different fuels. These two are relatively easy to see in our daily life. So what is the specific difference between them? Let’s analyze it below:
1. The structures of the two are basically the same, and one obvious difference can be found from their names: the required fuel is different. Diesel has a higher calorific value than gasoline, which burns more smoothly.
2. The power is different. The same reason that a diesel-burning car has more horsepower than a gasoline-burning car. The minimum power of a diesel generator set is 8,000 watts, and the maximum power can reach 2,000 watts. The maximum power of gasoline with the same volume can only reach 10,000 watts.
3. Different ignition types. In the cylinder of a gasoline engine, the mixture of fuel and air is ignited by a spark plug. In a diesel engine, the mixture is ignited by the heat of compression.
4. The volume is different. The gasoline engine is small in size and easy to carry, and is suitable for mobile power supply.
5. The mixture of fuel and air is different. In a gasoline engine, fuel and air are mixed in the carburetor and intake manifold. In a diesel engine, the mixing of fuel and air takes place after the diesel is drawn into the cylinders.
6. The main purposes are different. Diesel engines are mainly used for industrial power supply, and gasoline engines are generally used for household use
Gasoline generators are inefficient, and a gasoline engine of the same quality generates less electricity than a diesel generator of the same quality.
The price of gasoline is high, and the price of gasoline of the same volume is higher than that of diesel. Gasoline has the same density as diesel.
Diesel is safer to store than gasoline. Gasoline ignites at more than 400 degrees Celsius under normal pressure. Fuel with a higher ignition point requires a spark plug engine. Diesel is a fuel that ignites at about 200 degrees Celsius under normal pressure
The output power of a diesel generator is greater than that of a gasoline engine. The maximum power of a general gasoline generator is only 10kw, while the minimum power of a diesel generator set is 8kw, and the maximum power can reach thousands of watts.
Diesel generator sets have many single-unit capacity levels and are easy to configure. In terms of capacity, it ranges from a few kilowatts to several thousand kilowatts. According to the purpose and load, the optional capacity range is relatively wide. Using a variety of capacities, one or more units can be used as a backup power supply, and the installed capacity can be flexibly configured.
The supporting equipment of the diesel generator set is relatively simple, less auxiliary equipment, small in size, light in weight, flexible and convenient, and easy to move. Diesel generator sets are mostly configured independently, while standby or emergency sets are generally used in conjunction with distribution equipment.
The effective thermal efficiency of the oil generator is relatively high, about 30%~46%, so its fuel consumption is relatively low.
The start-up time of a diesel generator generally only takes a few seconds. In an emergency state, it can take full load within 1 minute, which means that it starts quickly and can quickly reach full power. The shutdown process of a diesel generator is also very short, and it can be started and stopped frequently. So the diesel generator set is very suitable as an emergency or backup power supply.
The above is the difference between diesel generators and gasoline generators, I hope to help you have a better understanding of the two.
