Q: Recently, the new type of diesel engine assembled on a three-wheeled low-speed automobile has experienced a serious oil consumption. Is this the cause? Ma Yingqiang Answer: The diesel engine compression system is seriously worn out, the piston assembly is wrong, the joints at the joints of the machine are damaged, and the oil shell side wall is damaged. This is the cause of excessive oil consumption. 1. When it is found that the oil consumption is too high, first check whether there is oil leakage at the joints of the body and the gear chamber cover, the large wheel on the side of the wheel, the rear cover, and the cover. If oil leaks, it should be observed that the gaskets at each joint are intact, and the damaged gaskets must be replaced. If the seal is complete, check the looseness of the connecting screws at each location. Use a wrench to loosen the bolt to the specified torque. If the above parts are normal and the oil leakage is at the rack position, check the oil casing. The main inspection location is on the front side of the oil tank side on the same side as the traveling wheel. Loose screws on the base are used to pull the wheel in the V-belt. A long-term collision with the angle iron on the frame of the protection oil shell is caused, and the oil shell is worn out to form a gap and generate oil leakage. 2. Normal wear caused by long-term use of the engine, or abnormal wear due to improper maintenance, will cause the cylinder liner of the diesel engine to form a longitudinal pull, and the bore and piston side clearance exceeds the specified value, so that the support force of the piston ring is reduced accordingly. Small, there is no net phenomenon. Or because the inner ring in the oil ring distorted the spring to break in the opening position of the oil ring, resulting in the oil is not clean and participate in the combustion, resulting in serious consumption of oil symptoms, manifested as diesel engine start difficulties, the exhaust pipe has obvious blue smoke Severe respirator injection. In addition, the piston should be on the upward side. When the assembly is reversed due to the direction of the direction of the combustion chamber to form an inverted state, although it will not affect the start of the diesel engine, but the loss of oil will be quite serious, the daily fuel consumption is about 0.5 kg. 3. Although the situation that the valve guide tube wears badly and burns engine oil is rare, according to the introduction of relevant information, it is also a reason that cannot be overlooked.
