초록
The purpose of this paper is to study the fuel economy improvement experimentally when the viscosity of engine oil is lowered. The emissions are measured for CVS-75 mode with SAE viscosity grades. The test results indicate that a close correlation has been found between the engine oil viscosity and the fuel economy. The lowering of engine oil viscosity causes the reduction of friction loss which has a very close relation with the fuel economy. These results as the lowering of engine oil viscosity will be a important factor for improvement of the fuel economy and reduction of the CO2 emission.
