Analysis of the causes of high temperatures in four-cylinder Perkins diesel engines.
1. Insufficient coolant.
Coolant is the medium through which the engine dissipates heat, and when there is not enough coolant, it can cause the engine to overheat. Therefore, it is necessary to check the level of coolant regularly during use, and add it in time if it is found to be insufficient.
Second, the radiator failure.
The radiator is an important part of the engine heat dissipation, if the radiator fails, it will affect the effect of engine heat dissipation, resulting in high engine temperature. Therefore, it is important to check the radiator regularly to ensure that it is working properly.
3. Pump failure.
The water pump is one of the important components of the engine cooling system, and its main role is to circulate the coolant. If the water pump fails, it can lead to poor coolant circulation, which can overheat the engine. Therefore, it is necessary to check the pump regularly to ensure that it is working properly.
Fourth, the thermostat is faulty.
Thermostats are an important part of engine temperature control, and if they fail, they can cause the engine to be too hot or too low. Therefore, it is important to check the thermostat regularly to ensure that it is working properly.
5. The ignition time is incorrect.
Ignition time is an important parameter of the engine ignition system, if the ignition time is incorrect, it will cause the engine to overheat. Therefore, it is necessary to check and adjust the ignition time regularly to ensure that it is working properly.
6. Insufficient or poor lubricating oil.
Lubricating oil is an important medium for engine lubrication, and if the lubricating oil is insufficient or poor, it will cause the engine to overheat. Therefore, it is necessary to regularly check the oil level and oil quality of the lubricating oil to ensure that it is working properly.
To sum up, there are many reasons why a four-cylinder Perkins diesel engine is hot, and it needs to be examined and diagnosed from multiple aspects. In the usual use process, regular care and maintenance should be carried out to ensure the normal operation of the engine.
