Abstract
For revealing the effect of engine oil on fuel consumption and durability, two engine oils of different viscosity grade (the candidate oil 5 W-30 diesel engine oil and the reference oil CI-4 15 W-40 diesel engine oil) were chosen to carry out proving ground test and chassis dynamometer test. Due to the differences between existed drive cycles and real conditions in China, a drive cycle of EMS vehicle in Beijing was established that could represent the real driving condition of EMS vehicle in Beijing. The result of the proving ground test using the driving cycle of EMS vehicle in Beijing showed that the candidate oil had a decrease of 1.5–2.5% BSFC compared to the reference oil. The result of chassis dynamometer test showed that the candidate oil had a total of 3.8% less fuel consumed in L/100 km compared to the reference oil. The field test indicated that the low-viscosity engine oil provided durable protection for engines.
