Which Weichai series generator is better than the imported unit?

1. If the generator you buy is used for a long time and is commonly used, it is recommended to buy an imported generator set. In the process of use, after a long time, it is inevitable that there will be such and such problems, which will bring a lot of unnecessary trouble. Because the quality of imported generator sets is indeed much better than that of domestic generators, these problems can be reduced.

2. Large generator set brands include imported units, joint venture units and domestic units.Imported crew brands such as Volvo, Perkins, etc. are big crew brands. The joint venture crew Cummins is very cost-effective. Domestic crew Yuchai is a very good crew brand.

3. Maintenance and accessories: No matter how good the quality of the generator set is, it is impossible to fail. If there is a problem, it involves maintenance and accessories. Domestic engine maintenance is relatively convenient, especially accessories. Many diesel engine accessories can be bought in county-level cities in China.

4. The generator set is powered by the diesel engine of Shandong Weifang Weichai Power Co., Ltd., which is equipped with well-known brand generators.

5. Commonly used units. This kind of generator set operates all year round and is generally located in areas far from the power grid (or city power) or near industrial and mining enterprises to meet the construction, production and living electricity consumption in these places.

Why does the injection nozzle of Boduan diesel engine often break?

The reasons for this situation are as follows: when the fuel injector is installed, the gasket is leaking or the gasket is destroyed, resulting in air leakage, causing the local temperature of the fuel injector to be too high and stuck.The pressure of the fuel injector is too low, causing the high-pressure gas in the combustion chamber to rebound.

Hello, there is no high-voltage fire. Check whether the high-voltage package is damaged and whether the high-voltage line is not energized or damaged. There is no low-voltage electricity in the fuel injector. Check whether there is a short circuit in the fuel injector line. Check and repair in time.

There are impurities and carbon accumulation on the outside that are insufficient combustion, which makes the fuel injection nozzle too dirty. In this way, carbon accumulates inside the engine cylinder, and there will also be phenomena such as acceleration wear of the cylinder and piston ring, resulting in unstable idling speed, increased fuel consumption, weak acceleration, difficulty in starting and emissions exceeding the standard.

If there is no problem with the supercharger, it is possible that the valve oil seal is aging. There is not a little oil. You should cut the cylinder to see if the rotation of each cylinder is the same. There is something wrong with the cylinder injector with the less rotation. If it is water, it is generally the cylinder head with cracks or sand marks.There may also be a crack in the cylinder liner.
