1. Diesel purification.Diesel oil contains a variety of minerals and impurities.If it is not precipitated and purified,it will affect the work of the plunger and the fuel injection head, resulting in uneven oil supply, etc.,reducing engine power and increased fuel consumption.Therefore, the diesel oil is needed to stand for a period of time,so the impurities are precipitated,and remembering filtering the funnel while refueling.

2. Maintain water temperature. If the temperature of the cooling water of the diesel engine is too low, the combustion of the diesel oil will be incomplete, affecting the power consumption and wasting fuel. Therefore, it is necessary to use the thermal insulation curtain properly. It is preferable to use soft water containing no minerals, such as flowing river water, for the cooling water.

3. Remove carbon deposits. In the diesel engine, there are polymers attached to the valve, the injector and the top of the piston. These carbon deposits will increase fuel consumption and should be removed in time.

4. Do not overload the work. Black smoke is emitted during mechanical overloading, which is fuel emissions that are not fully burned. As long as the machine often emits black smoke, it will increase fuel consumption and shorten the service life of components.

5, regular inspections, timely maintenance.
