In view of the serious wear of the connecting rod of the diesel engine, in order to avoid the hard impact of the piston connecting rod mechanism on the crankshaft and ensure the normal operation of various components, we immediately replaced the connecting rod, and unexpectedly the diesel engine was accidentally easy to install. Started. Although the problem is solved, why the connecting rod wear exceeds the limit will cause the diesel engine to start difficult. Through careful analysis to find the cause of the fault. It turned out that when the connecting rod wears badly, the gap between the crankshaft connecting rod journal and the connecting rod has far exceeded the wear limit, resulting in the piston at the position farthest from the centerline of the crankshaft. The required top dead center position, but the piston is at the position closest to the centerline of the crankshaft, can not reach the design bottom dead center position, which affects the ratio of the total cylinder volume to the combustion chamber volume, and reduces the compression ratio, resulting in the diesel It is difficult to start.

The repairman disassembled the gearbox and found no fault, but he was still unable to perform normal work after being replaced. Had to ask the repairman to replace the gear, the fork, the fork shaft, the fork spring, the steel ball, etc., and the result still cannot be eliminated. The machine operator went to the agricultural station for assistance. I checked: 1. The lever, the main gear lever, the correct position of the operation part; 2. The dismantling of the gearbox cover, the checkout of the fork meshing position and installation are all in accordance with the requirements; 3. Each Gears, shafts, bearings, etc. are all intact. When in-depth inspection of the rotary cultivator gear box, found that the gear is worn and the gear teeth are not straight, slanting sliding edge, so when using the second gear, the third gear, because the tilting force of the rotary cultivator gear is greater than the positioning force of the fork ball spring, The reverse gear is caused to slide to the reverse gear position to cause chaos. The normal use of the first gear is because a gear of the reverse gear and the gear of the cultivator are always meshed with each other, and the first gear is meshed with the main shaft teeth. Therefore, after replacing the rotary gear box gear, the fault was eliminated.

Electric Mini Car

Electric vehicles are the development direction of future transportation vehicles, which have the characteristics of environmental protection and low-carbon, and can reduce exhaust emissions and environmental pollution.

An electric vehicle is a type of vehicle that uses electrical energy as its power source. Compared to traditional internal combustion engine vehicles, electric vehicles have lower energy consumption, lower pollution emissions, and lower noise. With the increasing awareness of environmental protection and the development of technology, electric vehicles have become an important choice for solving energy problems and alleviating environmental pollution.
