Industrial Micro Generators Prefer Diesel Engines Over Gasoline Engines

Why do many industrial micro-generator sets use diesel engines instead of gasoline engines? That's because diesel fuel is safer to store than gasoline. For power generation, you just need to place it there, and there's no need to pursue any specific proportion. It doesn't matter if the diesel engine is a bit bulky, so in the long run, diesel engines are more suitable for micro-power generation equipment. Now, the editor from Dingbo Power Generator Manufacturer will explain this in detail for everyone.

For example, diesel engines with a power of around 100-200kW. Why don't these generator sets use gasoline engines as the power source? Even with a high power of over 100kW, their volume is 75% smaller than the currently used Shanghai Diesel engines. The energy conversion efficiency of diesel engines is much higher than that of gasoline engines, which is related to their own working principles. Moreover, the price of diesel is cheaper, so diesel should be a more ideal fuel. A rough comparison of their characteristics should explain your question:

1.The auto-ignition point of diesel is much lower than that of gasoline. Therefore, as long as the compression ratio of the diesel engine is appropriately increased to reach a certain pressure and temperature, it can ignite by itself without the need for an additional spark. Sparks also consume energy, and with a high compression ratio, the working distance is increased, along with more air. Diesel engines are basically equipped with turbochargers, which can further improve energy utilization. Therefore, diesel engines have the characteristic of high torque but relatively low rotational speed, making them more suitable for use in large machinery.

2.Gasoline is not as easy to auto-ignite, so the ignition method is used. The compression ratio is only around 10, and it is characterized by high rotational speed but relatively low torque. Also, due to the compression ratio and ignition method, the energy conversion efficiency is much lower.

3.The working method of diesel engines determines that they must be larger in size. With the same technology, they also vibrate more violently and produce more noise, making them less suitable for small cars and small equipment. Exhaust emissions are also a major issue. Gasoline engines are much better in this regard, with smaller size, lower noise, and relatively better environmental friendliness. Therefore, they have always been more commonly used in small cars.

Therefore, in summary, diesel and gasoline each have their own advantages and disadvantages, depending on the specific application. You can make a targeted choice based on your own situation. However, for industrial micro-generators, diesel engines are more suitable.
