What are the reasons for the Yuchai generator not starting? So what are the corresponding countermeasures?
1. Application technology of Yuchai generator
1. The air pressure in the air bottle is too low.
Elimination measures: The pressure in the bottle should always be kept above 2mpa.
2. No longer the best starting position.
Elimination measures: Turn the flywheel to 15° behind the top dead center of any cylinder.
3. The driving handle is not in the driving position.
Elimination measures: Tighten the driving handle in the driving position.
4. The diesel engine has a load.
Elimination measures: remove diesel engine load.
5. The lubricating oil of Yuchai generator has poor fluidity (in winter).
Elimination measures: lubricating oil or heating lubricating oil as specified.
6. The fuel system is not vented.
Elimination measures: deflate as required.
7. Diesel contains water.
Elimination measures: check the fuel tank; unscrew the lower screw plug of the diesel filter to remove water.
8. The bleed screw of Yuchai generator injector is loose.
Remedy: Tighten in a clockwise direction.
9. The quality of diesel oil.
Elimination measures: choose diesel oil according to regulations.
10. The working environment temperature of the diesel engine is too low.
Elimination measures: Work as specified.
11. There is no oil in the diesel tank or the oil valve is not opened.
Elimination measures: refuel or release the oil valve.
2. Yuchai generator fuel system
1. There is oil leakage from the oil pipe joint.
Remedy: Check and tighten fittings.
2. The oil pipe is blocked.
Elimination measures: Check, blow through and clean.
3. The diesel filter is blocked.
Elimination measures: disassemble and clean or replace the filter.
4. Yuchai generator diesel spray is not good.
Elimination measures: Adjust or repair the sprayer and replace the needle valve coupler if necessary.
5. The fuel injection advance angle is incorrect.
Elimination measures: Adjust the fuel injection advance angle to 29°±1°.
6. The shooting oil pump or injector is damaged.
Elimination measures: repair or replace.
Third, the diesel engine itself
1. Yuchai generator gas valve leaks oil.
Elimination measures: train the air valve and readjust the air valve clearance.
2. The cylinder leaks oil.
Elimination measures: Check each air cushion and slow down each cylinder head nut.
3. Piston ring leaks.
Elimination measures: replace the piston ring.
4. The valve spring of Yuchai generator is disconnected.
Elimination measures: replace the valve spring.
5. The piston bites in the cylinder.
Elimination measures: disassemble the cylinder for repair.
6. Water accumulated in the cylinder of Yuchai generator.
Elimination measures: remove the cylinder head, remove the water and find the cause.
7. The timing of the air-conditioning distribution plate is incorrect.
Elimination measures: disassemble the air-conditioning distribution plate and reinstall it.
