Regularly check the battery voltage, electrolyte level and connection status to ensure the normal operation of the battery.

Overheating can be caused by several factors. Check the coolant level and refill if necessary. Inspect the radiator for blockages and clean it thoroughly. Verify that the thermostat is functioning correctly and replace it if it's faulty. Check the water pump for leaks or damage, and ensure the cooling fan operates properly. If overheating persists, inspect the cylinder head gasket for leaks.

1.The climate is cold in winter, the ambient temperature is low, the viscosity of the engine oil increases, and the friction resistance of each moving part increases, which reduces the starting speed and makes it difficult to start.

2.The battery capacity decreases as the temperature drops, which further reduces the starting speed.

3.Due to the reduction in starting speed, the leakage of compressed air increases, and the heat dissipation of the cylinder wall increases, which greatly reduces the temperature and pressure of the air at the end of compression, and increases the delay period of diesel ignition. In severe cases, it may even fail to burn.

4.The viscosity of diesel at low temperatures increases, which reduces the injection speed. In addition, the swirl speed, temperature and pressure of the air at the end of compression are relatively low, which makes the atomization quality of the diesel injected into the cylinder poor, making it difficult to quickly form a good combustible gas with the air and ignite and burn in time, or even fail to ignite, resulting in difficulty in starting.

Possible internal component wear, clogged filter, oil contamination, or insufficient system pressure.

Solution: Replace worn components, clean or replace filter, replace hydraulic oil, check and adjust system pressure.
