What is engine repair
The engine is an important project in car repair. It is usually between minor repairs and overhauls, mainly focusing on the inspection and replacement of key components inside the engine. When the engine experiences problems such as power drop, fuel consumption increases, abnormal noise or burning of engine oil, the middle repair can effectively restore its performance and extend its service life.
1. Main contents of engine repair
Engine repairs usually include the following items:
| project | Specific content |
|---|---|
| Piston ring replacement | Check and replace worn piston rings to solve the problem of burning engine oil |
| Valve grinding | Repair valve sealing and improve combustion efficiency |
| Cylinder liner inspection | Measure the wear level of cylinder liner and perform cylinder boring if necessary |
| Crankshaft bearing replacement | Replace worn crankshaft bearings to reduce engine noise |
| Timing system maintenance | Check timing belts or chains to avoid tooth jumps or breakages |
2. Determination of timing of engine repair
Engine repair may be required in the following situations:
| Phenomenon | Possible Causes | Solution |
|---|---|---|
| Motor oil consumption too fast | Piston ring or valve oil seal wear | Replace relevant parts |
| Significantly reduced power | Insufficient cylinder pressure or insufficient combustion | Check valves and piston rings |
| Abnormal engine noise | Crankshaft bearing or connecting rod bearing wear | Replace bearings |
| Blue smoke coming out of exhaust pipe | Fierce engine oil burning | Maintain piston ring and valve seal |
3. Advantages of engine repair
Compared with major revisions, intermediate revisions have the following advantages:
| Comparison items | Middle school student | Overhaul |
|---|---|---|
| Repair cost | Lower | Higher |
| Repair time | Shorter (usually 3-5 days) | Longer (more than 7 days) |
| Repair scope | Local key components | Overall disassembly of the engine |
4. Precautions for engine repair
1.Choose a professional repair shop:Engine repair involves precision components and needs to be operated by experienced technicians.
2.Use original accessories:Poor quality accessories may cause secondary damage and affect the engine life.
3.Regular maintenance:After the intermediate repair, the oil and filter should be replaced strictly in accordance with the maintenance cycle.
4.Pay attention to during the running-in period:The engine after the intermediate repair needs to go through a running-in period of 1,000-2,000 kilometers to avoid high load operation.
5. Related topics and engine repairs
Recently, the rapid development of new energy vehicles has triggered discussions on traditional fuel vehicle maintenance technology. However, fuel vehicles still occupy the mainstream of the market, and engine repair technology is still an important skill in the auto repair industry. In addition, with the prosperity of the used car market, the demand for engine mid-repair is also increasing, becoming the focus of consumers' attention.
In summary, engine repair is an effective means to extend the engine life and restore power. Car owners should promptly inspect and repair the vehicle according to the condition of the vehicle to avoid small problems and major failures, thereby saving maintenance costs and ensuring driving safety.
