What are the reasons for a high-pressure common rail engine failing to start?
1 Answers
High-pressure common rail engine failing to start may be caused by the following reasons: 1. Abnormal or no voltage in the starting circuit. 2. Insufficient battery voltage. 3. Fault diagnostic instrument or oscilloscope shows: crankshaft, camshaft working, phase error. 4. Glow plug failure. 5. High-pressure fuel pump failure, injector abnormality or rail pressure abnormality. Here is some extended information about electronically controlled diesel engines: 1. Concept: An electronically controlled diesel engine is a diesel engine that uses electronic control for fuel injection and emissions. 2. Composition: The injection system of an electronically controlled diesel engine consists of three parts: sensors, ECU (computer) and actuators. Its task is to electronically control the fuel injection system to achieve real-time control of fuel injection quantity and injection timing under operating conditions.
