Forklifts may encounter the problem of weak engine during use, and I believe everyone will often be troubled by this issue. Today, let me introduce to you how to solve the problem of weak forklift engine.
1. The fuel supply pump is insufficient and needs to be repaired or replaced.
2. When the air filter is blocked and the intake is not smooth, it is necessary to replace or clean the filter;
3. If the diesel filter is blocked, it needs to be replaced
4. Insufficient oil supply in the low-pressure oil circuit, blockage of the fuel tank vent, blockage of the oil pipe, loosening of cracked joints, and inadequate sealing of the gasket. It is necessary to identify the fault, clear the oil circuit, and replace it.
5. If there is air or moisture in the fuel system, it can be eliminated.
6. The throttle cable is not adjusted properly and needs to be adjusted.
7. When the exhaust pipe or muffler is blocked and the exhaust is not smooth, cleaning is necessary.
8. The engine temperature is too high. Check the cooling system to identify and troubleshoot the problem.
9. The fuel injection pump has insufficient fuel injection and needs to be calibrated.
10. Individual fuel injectors have poor atomization, and it is necessary to find out where the cylinder malfunction is and replace or repair the fuel injector.
11. The fuel injection time is too early or too late and needs to be adjusted.
12. Mechanical factors cause low cylinder pressure. Mechanical factors include poor valve closure of the valve train and severe wear of the pistons, piston rings, and cylinder liners. Usually, the valve clearance is adjusted, the valve is re polished, or the piston, piston ring, and cylinder liner are replaced.
