Increase the cooling water temperature of the diesel engine: The normal water temperature of the diesel engine is 65-95°C, while the water temperature of most machines is lower than 50°C. As a result, diesel fuel cannot be completely burned, and the viscosity of the oil increases, and the wear resistance of the parts increases, resulting in increased fuel consumption. Ensure the best fuel advance angle: such as 195 diesel engine fuel supply advance angle of 16-25 degrees. After the diesel engine is used for a period of time, due to the wear of the plunger member and the injection pump transmission member, the fuel supply advance angle will be reduced, resulting in too late oil supply and large oil consumption. Keep the machine from oil leakage: The diesel engine often leaks oil due to the flatness of the oil pipe joints, and the gasket deformation or damage. To solve this problem, the gasket can be coated with valve sand, placed on a glass plate to be leveled, connected to a fuel pipe connector, or an additional diesel recovery device, such as a bicycle cap instead of an air core screw, welded to the fuel tank. The plastic pipe connects the return pipe of the nozzle to the air-core screw, allowing the oil to be injected into the tank. Do a good job of oil purification: More than half of diesel engine's faults are in the oil supply system. One of the exclusion methods is to reuse the purchased diesel for 2-4 days to precipitate 91-98% of the impurities contained in the diesel fuel. Changing the supporting phenomenon of the "big horse-drawn car": "The phenomenon of a large machine with a small pump" is also one of the reasons for wasting power and increasing fuel consumption. Under the condition that the existing equipment is not changed, the speed of the pump is appropriately increased so that the flow, lift and shaft power can be increased at the same time, which can achieve the purpose of energy saving and fuel saving.
