How to cool a sweeper engine in summer

What can be done to cool the road sweeper better is summarized in three points:

First, keep the engine operating temperature normal. If the working temperature is too low or too high, fuel consumption will increase and the wear of the machine parts will be accelerated. Because the coolant temperature is low, it means that the cooling intensity is too large and the heat loss is much. To maintain the normal operation of the engine, it is necessary to add the concentrated mixture, the concentrated mixture combustion is not complete, not only increase fuel consumption, but also dilute the lubricating oil, aggravate the grinding machine}; The coolant temperature is too high, indicating poor heat dissipation, high machine temperature, prone to deflagration and early A phenomenon, so that the cylinder inflation and engine power decline, fuel consumption increase.

Second, check the working condition of the silicone oil fan clutch, that is, check whether the engine starts to work when the water temperature reaches 80 to 85℃ and when the engine water temperature is lower than 70℃, whether the fan clutch is removed and whether the fan is idling; If idling, less power is consumed and less fuel is consumed.

Third, ensure cylinder pressure. Road sweeper cylinder pressure is a sign of the sealing quality of the cylinder. The cylinder sealing is good, the cylinder pressure can reach the standard value, the effective pressure generated by the working stroke of the engine is large, the combustion speed of the mixture after ignition is fast, the coolant and the exhaust gas with less heat, the economy of the engine is good.
