What are the reasons for a diesel car's lack of power and inability to accelerate?
1 Answers
The reasons for a diesel car's lack of power and slow acceleration are as follows: 1. Intake system failure: The resistance caused by a clogged air filter increases the intake into the cylinder, reducing the air volume, leading to incomplete diesel combustion and resulting in insufficient engine power. Regularly check the pipelines and connections for loose screws. For new cars that have been in use for a period, mandatory maintenance should be performed. 2. Fuel system failure: Blockage caused by debris in the diesel filter increases the flow resistance of diesel, reducing the amount of diesel entering the cylinder injected by the high-pressure fuel pump, which also decreases, causing insufficient output power of the diesel engine. Inspect and reinstall the low-pressure diesel pipelines, and replace them if necessary to ensure the diesel pipelines are unobstructed. 3. Issues with the electrical control system: Faults in the electronic control system lead to a sudden decrease in engine power, which is a common phenomenon. Incorrect head contact sensors being damaged or excessive sensor gaps can cause any minor issue to result in failure. If the vehicle can still be driven, find an OEM repair station to fix the fault as soon as possible.
