How to start the diesel generator in cold weather - Shijiazhuang generator rental 13811750017

The car has become a means of transportation for people to travel. With the increasing number of diesel generators installed in modern automobiles, the poor start-up performance of diesel generators in winter is a problem that drivers face. Therefore, the starting characteristics of the diesel engine, start-up skills, and how to start smoothly are important skills that the owner should master.

During the cold season, it should be warmed up

When the diesel engine is cold started, the fact that the compression ignition temperature of diesel cannot be reached is an important factor affecting the start-up performance. In this regard, hot water can be added to the engine cooling system to warm up, which is an effective way to improve the starting performance. The specific approach is: continuous heating water (let water out of the cylinder), and gradually increase the water temperature for preheating. Close the drain switch when the temperature of the outflowing water is high. In addition, an open fire such as a torch can be used to heat the oil pan to increase the flow properties of the oil to reduce the movement resistance of the parts.

Improve cylinder sealing performance

One of the differences between a diesel engine and a gasoline engine is the compression ignition type, so the cylinder is required to have a higher sealing performance. When the engine is cold-started in winter, there are few oils on the piston ring and the cylinder wall, and the sealing effect is not good. The phenomenon of repeatedly starting and not catching fire can occur. Sometimes the cylinder wears heavily and the cylinder's sealing performance is severely affected, making starting more difficult. In this regard, the injector can be removed and 30-40 ml of oil per cylinder is added to enhance the sealing performance of the cylinder and increase the pressure during compression.

Elimination of air in the oil circuit

Loosen the bleeder screw on the high pressure pump and pump the oil to drain the air in the low pressure circuit. Then, drain the air from the high pressure circuit. The specific method is to loosen the oil pipe joints on each fuel injector so that the throttle is in a large oil supply position and the crankshaft is cranked until the oil joints of the fuel injectors of each cylinder are out of the oil.

Of course, the selection of diesel fuel should ensure the flow performance at low temperatures in the area where the vehicle is driving. Otherwise, it will be difficult to start due to the improper use of diesel oil and its flowability. In addition, sufficient capacity and good performance of the battery should be ensured in the winter, which also helps to improve the starting performance of the diesel engine.

The start of the engine in winter is quite stressful. Usually, the crankshaft must be cranked first to make it easier to operate and start. The above methods should be selected according to the specific conditions, but also a number of options at the same time, the owner of the car may wish to personally try, will make it easy to start the diesel generator to start difficult
