The reasons for the high temperature of the diesel engine are:

　　1. Insufficient coolant;

　　2, the fan belt is too loose or faulty;

　　3, the water tank is leaking;

　　4. Poor heat dissipation of the radiator;

　　 5. The thermostat is malfunctioning.

　　The solution to the high temperature of diesel engine is:

　　1. Replenish the coolant in time;

　　2. Fasten the fan belt or replace it directly;

　　3. Repair or replace the water tank;

　　4. Clean up the debris on the surface of the radiator;

　　 5. Repair or replace the thermostat.

　　 Diesel engines are internal combustion engines that use diesel as fuel, and are compression ignition engines. When the diesel engine is working, the air sucked into the cylinder of the diesel engine is compressed to a high degree due to the movement of the piston, reaching a high temperature of 500 to 700 degrees Celsius, and then the fuel is sprayed into the high-temperature air in the form of mist, and mixed with the high-temperature air to form a combustible mixture The gas automatically ignites and burns. The energy released during combustion acts on the top surface of the piston to push the piston and convert it into rotating mechanical work through the connecting rod and the crankshaft.
