New energy vehicle training equipment to teach you how to maintain the engine

Nov 12, 2021

Practical training equipment of new energy vehicles is analyzed as follows:

Not scheduled maintenance of car engine

People like to spend a lot of money on modifications, but they simply neglect to maintain their engines as scheduled. Experienced auto mechanics say that poor engine maintenance accounts for 50 percent of the car repairs they handle. It can be seen that engine maintenance can play a vital role in the service life of extended vehicles.

Car oil change and oil filter element is not smooth

Different grades of smooth oil in the use of the process of oil will occur changes. After the vehicle travels a certain distance (BBS), the function will deteriorate, which may bring various problems to the engine. In order to prevent the onset of these problems, should be combined with the use of timing to car oil, and make oil moderate, generally between the upper and lower limits of the oil gauge as well.

Oil passes through a fine hole in the oil filter, deposing solid particles and gunk in the filter. If the filter block, oil can not be smooth through the filter core, will burst the filter core or open the safety valve, from the bypass valve through, still put dirt back to the smooth place, promote the engine wear accelerated, internal pollution increased.

Original geothermal car in winter

The main reason for hot cars is that the oil in the engine flows back into the oil sump below the engine after being parked for a long time. Although hot car is necessary, but idle hot car method is not advisable, because as long as the engine is moving, the rest of the rest did not move, kinetic energy can not change, as long as the road after gradually moving for a period of time to improve the engine operation.

Correct hot car method should be, after starting 30 seconds to a minute on the road, but at the moment must not travel with high speed, should insist on low speed, the engine speed does not exceed 3000~3500 to limit, generally adhere to 2000 turn, otherwise the engine and gearbox suffered by the violent wear but cannot recover. When the engine temperature rises to the normal operating temperature (approximately 3 to 5 minutes), the engine is ready to resume normal control.

The water tank rusts and scales

Engine water tank rust, scaling is the most common problem. Rust and scale will restrict the cooling fluid in the cooling system, the cooling effect will lead to engine overheating, and even cause engine damage. Timing use water tank powerful and efficient cleaning agent to clean the water tank, remove the rust and scale, not only to ensure the normal operation of the engine, but also to extend the life of the water tank and the engine.
