Abstract

Abstract:

A research and development of low viscosity and energy saving engine oil (FA-4/5W-30) were carried out to further reduce the fuel consumption to enhance the market competitiveness of the new generation of CN6 heavy-duty diesel engine. The computer aided engineering (CAE) was employed to do the simulation analysis. The test on the bench and the bench reliability test were carried out for the fuel economy of the corresponding CN6 heavy duty diesel engine. The results show that the newly developed low viscosity energy saving engine oil can effectively improve fuel economy by about 1%, which can meet with the engine reliability requirement. This research makes full preparation and accumulates the data for the subsequent market application of lowviscosity energy saving engine oil (FA-4/5W-30).

Key words: heavy-duty diesel engine, low viscosity and energy saving engine oil, energy saving
