In recent years, with the rapid development of the automobile industry, people have researched and developed a large number of new lubricating materials, which gives users more room to choose the lubrication varieties. A large number of practices have proved that the use of new high-quality engine oil can ensure long-term normal operation of the engine under more severe conditions of use, maximize power, reduce maintenance costs, save energy, reduce pollutant emissions and improve overall economic benefits.
In order to further analyze the impact of oil quality on environmental protection, energy saving and mechanical parts wear, we conducted comparative tests on different quality oils on the engine. Fuel consumption rate is an important indicator for evaluating the economic performance of internal combustion engines, and it is closely related to the quality of oil. It is the change in fuel consumption rate of two test diesel engines. Its fuel consumption rate has been continuously improved with the progress of the test, and its dynamic and economic indicators are more stable. The reason for the analysis is mainly that the friction between the parts after the use of the oil is reduced, the sealing performance of the cylinder is improved, and the fuel is fully burned.
As the speed decreases, the fuel consumption rate and smoke are significantly reduced. The destructive test results of the turbocharger oil are in the state of cooling and lubrication of the inorganic oil. The supercharger can be operated at high, medium and low speeds for 10 minutes; It shows that the rotor shaft and the floating bearing are not burned, the radial clearance is slightly increased, and the engine is restarted, and the supercharger can still operate normally, indicating that the oil has high wear resistance and high temperature resistance. Compared with the test results of ordinary oil test, the intuitive wear state of the friction surface of the main shaft bush, the connecting rod bearing bush and the camshaft bushing of the engine using high quality engine oil has been significantly improved, and the mating surface between the cylinder sleeve and the piston works well and wears. The surface is relatively uniform, and the surface of the camshaft and the tappet is smooth and non-destructive; the use of the new high-quality engine oil in the plateau region can make the fuel economy rate of the diesel vehicle in the range of common road speeds reach 1.7% to 5.6%.
