This phenomenon is mainly caused by the electrical system, which may be caused by insufficient battery power, starter failure, and line failure. For battery failure, it is necessary to charge the battery in time, and check whether its power and electrolyte reach the specified height. If the battery is found to have poor charging or aging components, it will be eliminated. In the daily use of the battery to do a good job of daily maintenance, to avoid loss of power phenomenon.
The second is the oil circuit failure. The fuel of the high pressure pump is transported through the low pressure oil pipe, under the action of suction produced by the injection pump and the oil transport pump, and once the air enters the oil pipe, it will produce gas resistance, resulting in oil circuit blockage. If the low-pressure oil circuit leaks, or the oil level in the tank is too low, the vehicle is parked on a slope or on the way, the air will have a chance to enter the oil circuit. If the working environment temperature is very high, the fuel will be volatile, and it is possible to form gas resistance in the low pressure oil circuit, which will lead to the engine not working normally, automatic shutdown or not starting at all.
The common fault parts of the oil circuit blockage are mainly the filter screen, the oil pipette, the balance of the oil tank cap, the diesel engine filter, etc. The main reason may be that the diesel oil that does not meet the specified value is used, or the oil is involved in impurities. Clean diesel and good sealing is the key to prevent oil circuit clogging, to do this, to carry out regular maintenance of the oil circuit, according to the situation to clean and maintain the diesel filter, as required to clean or replace the filter element of the filter.
The cleaning of the oil tank should be carried out in a timely manner according to the working environment and conditions, and the impurities in the oil tank should be thoroughly removed during the cleaning process to ensure that the box is clean and clean; There is also a situation that is easy to cause difficulty in starting the engine, that is, the oil valve and injection pump plunger coupling parts are used for too long, resulting in serious mechanical wear, and in this case, it is OK to replace the parts.
