First, PT fuel pump The main function of the PT fuel pump is to deliver the fuel plus low pressure (about 0.8~1.2MPa) to the injector. When the spindle oil seal at the PT pump coupling fails, the fuel will pass through the oil seal and enter the oil sump through the timing gear box. In […]

The diesel oil is not clean, causing the needle valve to accelerate the wear and closing. The gas turbulence caused by the high pressure combustion of the combustion chamber causes the needle valve fitting to ablate. Improper cleaning, use of unclean cleaning fluid or improper cleaning. The installation is not correct. The gasket at the […]
One: The steering wheel is not in a deadlock state. The solution is simple. Just force the steering wheel and turn the key. Generally, the steering wheel lock can be unlocked quickly. The ignition is an instant event. Two: Isn’t the gear returned to the P position when parking? Think about the fact that if […]
Introduction Production common rail fuel systems are equipped with a closed-loop high pressure control-system that stabilizes the rail pressure within a relatively small margin to the nominal value specified by the electronic control unit for a given engine operating condition. The pump maintains the rail pressure by continuously delivering fuel to the common rail. This […]
Injector checker adjustment pressure use method: Before using the detector, check whether it is fixed firmly. The working environment should be clean. The detector should be wiped clean especially at the joint of the injector. Then add No. 0 light diesel oil that has been precipitated for more than 48 hours. It is forbidden to […]
The characteristic of the fault diagnosis of the electronically controlled automatic transmission is to first determine whether the fault is in the circuit part or the mechanical part. If the fault light is on, the fault can be considered in the circuit part, otherwise it is in the mechanical part. When the vehicle is […]
The electronic control unit of the electronically controlled anti-lock system has a low failure rate. Therefore, most of the malfunctions of the electronic control device are not problems of electronic components, but are caused by poor connection of the wires or contamination of the components. If the fault code indicates that the sensor is faulty, […]
For electronically controlled fuel injection systems, the impact of air intake system leakage on engine operation is much greater than that of carburetor type cars. Because on the electronically controlled fuel injection engine, the air leakage is not measured by the air flow meter, and the air-fuel ratio has a great influence. Therefore, in the […]
The electronic controller (ECU) is a precision device. Although many fault phenomena may be related to the ECU Common Rail Bosch Nozzle, the failure rate is very low, so do not dispose of the ECU easily, and do not open the ECU cover casually. Circuit breakage or poor contact is a common fault in Common […]
After the hybrid power is used, the maximum power of the internal combustion engine can be determined according to the average power required, and the engine is relatively small (downsize). At this time, it is working under the optimal working conditions of low fuel consumption and less pollution. Since the internal combustion engine continues to […]
