CAT 320DL-C64. Engine maintenance information.
1. Overview. CAT 320DL-C6Engine 4 is a diesel engine that is widely used in construction machinery and heavy equipment. This article will introduce the key points of maintenance of this engine in detail to help maintenance personnel better troubleshoot and maintain it.
Second, the engine structure and working principle.
CAT 320DL-C64. The engine adopts in-line six-cylinder, water-cooled, turbocharged technology, with high power and torque output. Its working principle is as follows: the air filtered by the air filter enters the cylinder under the action of the turbocharger, and is mixed with the diesel fuel injected into the fuel injector to produce power. The exhaust gas after combustion is discharged through the exhaust pipe.
Third, the key points of maintenance.
1.Change your oil and oil filter regularly.
To ensure the proper functioning of the engine, the oil and oil filter must be changed regularly. It is recommended to replace the engine for the first time after 200 hours of operation and every 500 hours thereafter. When changing, make sure that the oil and oil filter are changed at the same time to maintain a good lubrication system.
2.Check the turbocharger.
The turbocharger is an important component of the engine and needs to be checked regularly. The supercharger air inlet should be cleaned regularly to keep it clean and free of dirt. If the supercharger is found to be leaking, unstable speed or abnormal sound, it should be repaired or replaced in time.
3.Check the cooling system.
The engine cooling system is critical to maintaining the normal operating temperature of the engine. Regularly check the level and concentration of the coolant, as well as the tightness of the cooling system, to ensure that the cooling system is leak-free. If the coolant is found to be abnormal, it should be replaced in time.
4.Check the fuel system.
The proper functioning of the fuel system is critical to the performance of the engine. Clean the fuel system regularly to ensure that the oil circuit is unobstructed. At the same time, the working condition of the fuel injector should be checked regularly, and if the fuel injector is found to be blocked or dripping, it should be repaired or replaced in time.
5.Check the cylinder pressure.
Cylinder pressure is an important parameter for judging the working condition of the engine. Check the cylinder pressure regularly to make sure it is within the specified range. If the cylinder pressure is found to be abnormal, the cause should be investigated and repaired in time.
4. Common troubleshooting and troubleshooting.
1.Difficulty in engine starting.
If it is difficult to start the engine, you should first check whether the starting circuit is normal and whether the battery power is sufficient. If the starting circuit is normal, the fuel system, cylinder pressure and ignition system should be further checked for faults.
2.The engine is overheating.
If the engine is overheating, you should first check whether the cooling system is working properly. If the cooling system is normal, it should be further checked whether the engine is overloaded, whether the ventilation is good, and whether the lubrication system is normal.
3.Abnormal engine noise.
If there is an abnormal noise in the engine, the abnormal noise should be judged first. If the abnormal noise comes from the outside of the engine, check whether the transmission belt, fan, water pump and other components are normal; If the abnormal noise comes from inside the engine, check whether the cylinder, crankshaft, bearing and other components are normal.
5. Summary. 
CAT 320DL-C64. As a high-performance diesel engine, the maintenance of the engine is very important to maintain the performance and service life of the engine. Maintenance personnel should be proficient in the structure and working principle of the engine, regularly maintain and inspect, timely investigate and troubleshoot, and ensure the normal operation of the engine. At the same time, correct use and maintenance methods are also of great significance to extend the service life of the engine and reduce maintenance costs.
