碩士 === 南臺科技大學 === 機械工程系 === 106 === Cold-start emissions are higher than other engine working conditions due to low engine temperature and unsufficient catalytic ignition temperature. NOX, HC and CO Emissions are the main pollution. They are highly regulated by the most advanced countries because they might effect people healthy and may be cancer causes. One conventional air-cooled engine with and without the thermal management system are compared in this experiment. The experiment was done in national standared emissions testing lab. The thermal management system is able to reduce heat loss at cold-start mode. Thus it is able to reduce emissions. The experiment results show that the air-cooled engine with thermal management system can reduce its emissions, NOX, HC and CO, by 5%-37% in both EU3 and WMTC driving cycles.
