1, increase the cooling water temperature. The normal water temperature of the diesel engine is 65-95, but at present it is generally lower than 45, causing diesel waste. 2, to ensure the best fuel supply advance angle. For example, the advanced fuel supply angle of the 195 type diesel engine is 16 degrees to 20 degrees. When the diesel engine is used for a period of time, due to the wear of the coupling plug and the fuel injection pump, the fuel supply advance angle will be reduced, causing the fuel supply time to be too late and the fuel consumption to increase. 3, to maintain the machine does not leak oil. The diesel engine often leaks oil due to flatness of the fuel pipe joint, deformation or damage of the gasket. Solution: (1) Place the gasket coated sand on the glass plate to flatten it and calibrate the tubing connector. (2) Add diesel recovery device. Replace the hollow screw with a bicycle cap, welded to the box. Use a plastic tube to connect the return line on the nozzle to the hollow screw so that the return oil flows into the tank. 4, to strengthen the oil purification. About half of the diesel engine's faults are on the fuel supply system. Solution: (1) Preserve the purchased diesel for 2-4 days before use. (2) If you buy it now, put two layers of silk cloth on the filter screen of the fuel tank of the diesel engine to filter out impurities with a diameter of 0.001 mm or more. 5, change the status of large machines with small water pumps. When a large machine is equipped with a small water pump, the number of diesel engine pulleys should be appropriately increased to increase the pump speed so that the flow, lift, and shaft power can be increased to achieve fuel economy. 6, adjust the injection pressure. The injection pressure of the 195 diesel engine is about 12 trillion. According to tests, when the injection pressure is less than 10 MPa, the consumption of diesel oil increases by 10-20 grams per kilowatt-hour. In order to maintain the normal injection pressure of the injector, the injector must be regularly adjusted. In rural areas, there are generally no injector calibration devices that can be checked and adjusted directly on the injection pump using a comparison method.
