摘要
近年来,随着汽车技术的不断进步及在节能减排政策的推动下,发动机正沿着大功率、小体积的方向发展。增压技术在新上市的汽油发动机上的应用也趋向于普及化,但是涡轮增压技术的广泛应用,导致发动机工作温度升高,热负荷增大,对发动机机油的使用也提出了相应的要求。在汽车运行过程中,机油适应性好与差,将对发动机的可靠性、耐久性产生显著的影响。确定机油的适应性需考虑发动机搭载整车后的运行工况和实际使用环境的多样性,仅通过试验室台架验证试验无法有效评估实际情况,因此选择试验车路试的方式进行验证。
In recent years, along with the advance of technology, and driven by energy conservation and emission reduction policy, the engine is developing along the direction of high power and small size. The application of turbo technology on new gasoline engines tends to spread. But as the wide use of turbo technology results in higher engine operating temperature and increased heat load, corresponding requirements on the use of engine oil are also put forward. In car running process, the adaptability of the oil will significantly influence the reliability and durability of the engine. To determine the adaptability of engine oil, the diversity of operation condition of the engine after powering vehicle and the actual operation environment should be considered. As laboratory bench test cannot effectively evaluate the practical situation solely, the vehicle road test method is selected for validation.
