Increase the temperature of diesel engine cooling water Normal temperature of agricultural diesel engine is 65°C～95°C, but the current temperature of diesel engine is generally lower than 45°C, so that the oil can not be completely burned, which promotes the viscosity of the oil, which increases the running resistance of the diesel engine. More oil. The solution is to increase the temperature of the diesel cooling water. The best angle for ensuring the best fuel supply advance angle for the 195 diesel engine is 16 to 20 degrees. When the diesel engine is used for a period of time, due to the wear of the plunger fitting and the injection pump transmission member, the advance angle of the fuel supply will be reduced and the fuel consumption will be greatly increased. The solution is to ensure that the advance angle of the fuel supply is greater than the optimal angle. To ensure that the machine does not leak oil The current diesel engine oil pipe is often due to uneven joint surface, gasket deformation or damage there is leakage of oil. The solution is: 1 The valve gasket is coated with valve sand and placed on the glass plate to flatten, which can correct the oil pipe joint. 2Increase the diesel recovery device. Bicycle spoke caps can be used instead of hollow screws to weld on the tank. Plastic pipes can also be used to connect the return pipe on the nozzle to the hollow screw so that the return oil flows into the tank. More than half of the faults in the diesel engine before the oil was used out of the fuel supply system. The solution is to: 1 buy back the diesel first settling precipitation 2 to 4 days, when used can precipitate 98% of diesel impurities. 2 If you buy it now, put two layers of silk or toilet paper on the fuel tank filler screen to remove impurities. Changing the "big horse-drawn car" approach is often seen as a "big machine with a small water pump" phenomenon when pumping water to land. It is actually a waste of energy. The improvement method is: appropriately increase the number of diesel engine pulleys, increase the speed of the pump in the case of a diesel engine running at a reduced speed, and increase the flow, lift and shaft power to achieve the purpose of energy saving. Adjusting the fuel injection pressure of the injector The fuel injection pressure of the injector of the 195 diesel engine is 120 kg/cm2. When the injection pressure is less than 100 kg/cm2, the fuel consumption will increase by 10-20 g/kWh. The improvement is that the pressure on the injection pump can be checked and adjusted directly with the comparison method.
