To increase the load, you need to increase the throttle to increase the power output. If the engine stalls when the throttle is applied, you can check if there is insufficient air intake, resulting in poor combustion. If the problem still cannot be resolved, the fuel injection timing may have a problem, resulting in insufficient power and blowing noise. Besides, if everything is normal with your diesel engine at no load, then it is likely that there is a problem with the generator windings and excessive resistance. This is not necessarily a problem with the diesel engine!
1. When the diesel generator set automatically stalls, the speed gradually decreases, the operation is unstable, and white smoke is emitted from the exhaust. This phenomenon indicates that there is water. in diesel and the cylinder seal is washed away by water, or damageages by automatic decompression, etc. ?
Measures: Replace the cylinder seal and adjust the pressure reducing mechanism.
Other extinction phenomena and solutions:
1. During automatic shutdown, operation is continuously unstable and accompanied by abnormal knocking noises. This phenomenon is a sudden mechanical failure.
Common causes: broken crankshaft, broken piston pin, loose or broken connecting rod bolt, valve lock part, falling valve circlip, broken valve spring or broken valve stem, causing the valve to fall, etc.
Measures: Stop the machine immediately for inspection to avoid major mechanical accidents. It can be sent to a professional maintenance point for multiple inspections.
2. When automatic shutdown, the speed suddenly decreases and black smoke is emitted from the exhaust pipe.
Reason. : The cooling system lacks water, the engine overheats, causing the piston to strain and jam in the cylinder liner, the friction pair is poorly lubricated, the shaft is burned, or the parts of the valve train are seized, etc., causing the engine to be removed and stalled.
Measures: Strengthen the maintenance of the lubrication system and cooling system, and add sufficient lubricating oil and cooling water.
Extinction:
Also called extinction. When the reactor is operating at a significant reaction rate, if the temperature of the feed inlet is lowered so as to reach the lower limit of the multiplet region, the reaction rate will suddenly drop significantly and the reaction will proceed. will practically stop. This phenomenon is called extinction. The corresponding inlet temperature is called the extinction point. Generally refers to thecar stalling.
