| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 93 === In conformity with the question of the energy crisis and greenhouse gas problem, this studies include the review of green cars (Hybrid car、Fuel cell car ) technologies, and the development of carbon emission control of internal combustion engine. The method of 3E and 6- Risks is used to evaluate the using of biodiesel and fuel cell car. It may offer the analysis of risks in technology, economy and ecology in order to reduce environmental load.
LCA(Life Cycle Assessment) is an objective process to evaluate the environmental burdens associated with a product, process, or activity by identifying energy and materials used and wastes released to the environment, and to evaluate and implement opportunities to affect environmental improvements. This study is to develop the deposits-cleaning machine and proceed the experimental work on cleaning the unburned carbon deposition. The experiments include utilizing the inlet manifold washing machine to make the real car test, and the feasibility about the gasoline additive prescription to remove accumulated carbon deposits.
The results show that the removal efficiency of the carbon monoxide can be up to 86% after washing, and the removal efficiency of the organic gas can be up to 70% ~ 93%. The results of adding gasoline additive also show that the removal efficiency of carbon deposits may reach the optimization when the 0.01% of nanometer additives are used.
