摘要:  Experiments researching about the effect of gasoline formulations on fuel economy and emissions were conducted on a modern gasoline direct inject (GDI) engine. The objective of this study was to explore the gasoline formulations that can alleviate energy crisis and greenhouse effect to some extent. Five gasoline blends with same research octane number (RON) were designed and tested on a calibrated GDI engine under mapping characteristics conditions. Results illustrate that the optimized fuel formulation improves the fuel economy and reduces carbon dioxide (CO2) emissions at medium loads and low speeds of engine. The BSFC decreased by the maximum value of 3.26% mainly owing to the improvement of combustion velocity and the optimization of lower heat value. The optimized fuel formulation simultaneously increases total hydrocarbon (THC) emissions, which barely observed in non-methane hydrocarbon (NMHC) emissions. Nevertheless, the optimized formulation fuel markedly reduces CO2 emissions, reaching the maximum value of 2.34%. The research results can practically applicate by refineries to reduce the CO2 emissions and alleviate the greenhouse effect.
