1, the engine can't start. When the car is driving, the engine stops and can't be restarted.
2. The fault of the transmission system makes it impossible for the car to run with the engine running, and the car cannot start running.
3. After parking in summer, you can't start driving again.
Second, the solutions to these failures.
1, the engine can't be started. When the car is running, the engine is turned off and can't be restarted. It should be checked according to the principle of circuit first, then oil circuit. Generally speaking, from the failure probability of two mechanisms and five systems of the engine, the failure rate of the electric ignition system is the highest, accounting for 47% of the total number of failures, and the oil supply system accounts for 18%, followed by others.
2. The fault diagnosis principle of the transmission system that makes the car unable to run under the running state of the engine and the car unable to start running is: check the transmission section by section.
3. This kind of fault mainly occurs in the main reducer, and it is very hot to touch the main reducer by hand. When the rear cover is removed, there is no gear oil in the shell, the gears and other parts have been burnt to purple-blue by high temperature, the planetary gear and the cross journal are sintered together and cannot rotate, the rolling resistance of the two rear wheels is inconsistent when the car starts, the differential can not share the torque equally, and the car can not start.
