What are the reasons why a diesel engine cannot accelerate when stepping on the throttle?

[VonBrandon]

The reasons why a diesel engine cannot accelerate when stepping on the throttle are: 1. Excessive carbon deposits in the vehicle; 2. Poor fuel quality; 3. Blockage in the intake or exhaust system; 4. Aging spark plugs; 5. Cylinder misfire; 6. Insufficient tire pressure; 7. Insufficient engine power; 8. Problems with the combustion chamber, ignition system, or valves. The solutions for a diesel engine not accelerating when stepping on the throttle are: 1. Clean carbon deposits; 2. Use standard gasoline; 3. Replace spark plugs. Maintenance for diesel engines: 1. Break-in: This is the foundation for extending service life; 2. Clean fuel, clean water, clean air, and clean engine body. Diesel and gasoline: These are the main fuels for the engine. If diesel or gasoline is not clean, it can cause wear on the precision components, increase the clearance, leading to oil leaks, dripping oil, reduced fuel supply pressure, increased clearance, blocked fuel lines, and bearing seizure faults; 3. Regularly check and tighten fasteners: Due to vibration, impact, and uneven load during the use of diesel and gasoline engines, bolts and nuts are prone to loosening. Adjustment bolts in all parts should be checked.
