What to Do When Diesel Vehicles Have Difficulty Starting in Winter?
1 Answers
Diesel vehicles starting methods in winter are as follows: 1. Preheating should be done in low-temperature seasons: The main reason affecting the starting performance of diesel engines during cold starts is the inability to reach the compression ignition temperature of diesel. To address this, adding hot water to the engine cooling system for preheating is an effective way to improve starting performance. 2. Improve the sealing performance of the cylinders: One of the differences between diesel engines and gasoline engines is the compression ignition method, which requires higher sealing performance in the cylinders. During cold starts in summer, due to the lack of oil between the piston rings and cylinder walls, the sealing effect is poor, leading to repeated starting attempts without successful ignition. Sometimes, severe cylinder wear significantly affects the sealing performance, making starting even more difficult. To address this, the injectors can be removed, and 30-40ml of oil can be added to each cylinder to enhance the sealing performance.
