| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系 === 107 === Global environmental awareness and energy tightening, in order to reduce vehicle emissions and improve engine performance, the research on the proportion of raw fuel added and the research and development of fuel injection systems are the current research directions to reduce fuel consumption and reduce emissions. In order to change the proportion of water added in biodiesel, the effects of engine combustion on fuel consumption rate, average effective brake pressure and exhaust emissions were discussed.
This study used a fixed proportion of biodiesel and made individual comparisons and discussions by varying the proportion of added water. According to the results of the engine horsepower experiment, the fuel consumption in this proportion does not affect the performance of the original diesel engine. Although the fuel consumption will increase, the use of an appropriate proportion of water in a fixed proportion of the biodiesel can reduce Smoke and NOx. And the emission of EGT concentration, and this proportion of addition can reduce the dependence on fossil fuel super diesel, it is worth promoting.
