Regularly checking and replacing the engine belt can prevent the belt from breaking and ensure the normal operation of the engine.

1. There must be enough starting speed. The high starting speed means less gas leakage in the cylinder, shorter heat transfer time of compressed air to the cylinder wall, less heat loss, and higher gas temperature and pressure at the end of compression. Generally, the speed is required to be above 100r/min.

2. The cylinder should have good sealing. This can further reduce the amount of leakage and ensure that the gas has sufficient combustion temperature and pressure at the end of compression. The compression pressure of the cylinder shall not be lower than 8_0_%_ of the standard value.

3. The engine is required to have appropriate clearance relative to the running parts and good lubrication.

4. The battery must have sufficient starting capacity and the technical condition of the starting circuit is normal.

5. The starting oil volume meets the requirements, the injection quality is good, and the injection advance angle meets the requirements.

6. Use fuel that meets the requirements

1. Most of the white smoke is caused by water in the cylinder. Please check whether there is water in the excavator diesel. Generally, the white smoke is emitted for a short time after starting, and there is no problem with the engine;
2. If the excavator starts to emit white smoke, the oil is not reduced, and the excavator works weakly, it means that the cylinder mattress of the excavator engine is worn;
3. Poor atomization of the injector and low cylinder pressure are also one of the reasons for the excavator engine to emit white smoke. Check the injector.

Kobelco excavator maintenance tips 1: Cooling to prevent air blockage In high temperatures in summer, the engine is prone to air blockage due to high speed and difficult heat dissipation, which makes it difficult to start the engine after stopping for a few minutes. Once air blockage occurs, the excavator driver should stop the engine immediately to cool down and eliminate the fault.

Kobelco excavator maintenance tips 2: Observe the water temperature gauge at any time to prevent water shortage When driving in high temperature weather, always pay attention to checking the cooling water volume and the water temperature gauge. When water shortage is found, immediately idle the engine to cool down before adding water, and be careful not to open the radiator cap immediately to prevent burns.

Kobelco excavator maintenance tips 3: Prevent engine oil from deterioration Lubricating oil is easily diluted by heat, resulting in poor oxidation resistance, easy deterioration, and even causing faults such as burning of the bearing and the shaft. Therefore, the crankcase and gearbox should be replaced with summer lubricating oil, and the amount and quality of the lubricating oil should be checked frequently, and replaced in time.

Kobelco excavator summer maintenance tips 4: timely cleaning of engine surface oil If the external oil of the engine is too thick, it will affect the heat dissipation and bury the hidden danger of failure of various parts. You can use the high-pressure spray method to clean the engine parts with a cleaning agent that does not corrode the body parts.

Kobelco excavator summer maintenance tips 5: prevent the water tank water temperature from being too high In summer, the cooling water of Kobelco excavators evaporates and consumes quickly. You must add enough cooling water before leaving the vehicle, and check the water level frequently during work. For single-cylinder diesel engines without a water temperature gauge, always pay attention to the red mark height of the water tank float. If the float cannot be used normally, it should be repaired in time. If the boiling phenomenon occurs during work, do not add cooling water directly. Stop the work, slow down the generator, and slowly add cooling water after the water temperature drops to avoid cracks in the water tank when it is cold.

Kobelco excavator summer maintenance tips 6: Ensure the best oil supply time In summer, the oil supply time of Kobelco excavators should be adjusted. If the oil is supplied too early, the engine will make a knocking sound and sometimes reverse; the oil supply time should not be too late, otherwise the engine will work weakly.

Causes of overheating may include low hydraulic oil level, clogged filter, excessive system load or cooling system failure.
