In terms of light-duty diesel engines, Isuzu is undoubtedly the king. As early as 1984 and 1985, this Japanese diesel engine and commercial vehicle giant established Qingling Motors and Jiangling Motors in Chongqing, Sichuan, China, and Nanchang, Jiangxi, China, respectively.t began producing Isuzu vans, light trucks and the corresponding 4JB1. engines.

With the deployment of Ford Transit, Foton Scenery and other light passenger cars, Isuzu engines have found a blue ocean in the light passenger car market. Today, almost all diesel engines used in vans, light trucks and light buses in China are purchased from Isuzu or produced using Isuzu technology.

Automotive engine overhaul mainly includes replacing valves, pistons, cylinder liners or cylinder boring, shaft grinding, etc. According to the 4S general stores standard, 4 components need to be replaced, namely pistons, piston rings, valves, valve oil seals, valve guides, crankshaft bushings, connecting rod bushings, timing belts and tensioners.

1. Whatprojects should be reworked?

In addition, the machining, lower bore cylinder sleeve, grinding shaft, cold press pipe and overhaul kit need to be replaced. replaced. Front oil seal, rear oil seal, camshaft oil seal, oil pump, valve, etc. Sometimes it is necessary to replace external parts, like clutch plates, etc. In short, it is necessary to replace all the parts that are. Not sure if installed. Engine repair ensures engine performance.

2. The mechanical part generally includes a set of intake and exhaust valves, a set of piston rings, a set of 4 cylinder liners (if it is a 4-cylinder engine), two thrust plates , and 4 pistons. ;

3. The cooling system generally mainly consists of the water pump (the palses of the pump are corroded or the hydraulic seal has water infiltration), the upper and lower water pipes of the motor, the high circulation iron. water pipes, small circulation pipes and butterfly water pipes (with aging problems). (If it expands, it needs to be replaced), thermostat, etc. ;

The fuel part generally includes the upper and lower oil. injector rings, fuel filter; the ignition part: if the high voltage line is swollen or leaking, replace it and the fire piston; the upper and lower oil rings of the fuel injection nozzle, fuel filter;

< p>4. Ignition Part: Replace the high voltage line if it is swollen or leaking and the piston is on fire;

5. Air intake The room usually consists mainly of air filters;

6. Other auxiliary materials generally include antifreeze, engine oilr, engine oil compartments, chemicals.Cleaner, engine metal cleaner or all-purpose water;

7. Components to inspect typically include whether the cylinder head is corroded or uneven, crankshaft, camshaft, timing belt tensioner, and timing belt adjuster. pulley, timing belt, engine outer belt and adjustment pulley, rocker arm or rocker arm shaft, if it is a hydraulic lifter, check the hydraulic lifter

8. or water seal leakage), engine upper and lower water pipes, large circulation iron water pipes, small circulation pipes, throttle water pipes (need to be replaced if old and swollen );

9. inside the overhaul kit, including cylinder gaskets and various types of oil seals, valve cover gaskets, valve oil seals, gaskets, etc. ;

Renovation projectsengine vision generally include engine overhaul, external treatment of the cylinder head plane, drilling the cylinder, cleaning the water tanks, grinding the valves, installing the cylinder liners, pressing the pistons, cleaning the oil circuits, maintain engines, maintain generators, etc.

2. Parts that must be replaced during engine overhaul

1. Valve oil seal set, a set of intake and exhaust valves, a set of plug rings and a set of cylinder liner with 4 tappets Two pieces, large and small tiles, 4 plugs,< /p>

2. The cooling system usually mainly consists of the water pump (the pump blades are corroded or the hydraulic seal is not leaking)

3. The upper and lower water pipes of the engine, the large circulation iron water pipe, the small circulation rubber pipe and the valve water pipe (need to be replacedif there is no aging and shrinkage

4. The fuel part usually mainly includes the upper and lower oil rings of the fuel injector and the fuel filter.

5 The ignition part usually mainly includes if the high voltage line does not have one . shrinkage or leakage. If not, replace the spark plug. The air intake part usually mainly includes the air filter.

6. Other auxiliary materials: antifreeze, engine oil if the cylinder head is corroded or uneven, crankshaft; , camshaft, reverse belt tensioner, reverse belt reset wheel, reverse belt, external motor belt and reset wheel, rocker arm or rocker arm shaft, if hydraulic lifter , please check the hydraulic lifter.
