Abstract
Disclosed is a quick-heating catalytic converter which allows the reduction of the unwanted emissions or pollutants created by the operation of an internal combustion engine. It comprises a catalytic converter system and an electronic heating catalytic system. In the catalytic converter system, the exhaust created by the operation of an internal combustion engine is oxidized or reduced to harmless emissions in the presence of a catalyst. The electronic heating catalytic converter system is located at a front position of the catalytic converter system and preheats the exhaust, comprising a power inverter circuit for inverting a direct current into an alternating current, a temperature-controlling circuit for controlling the temperature of the catalytic converter system, and a quick microwave heating circuit for quickly increasing the temperature of the catalytic converter within a few seconds to such an extent that the catalyst can readily function to purify the exhaust. The quick-heating catalytic converter allows the exhaust generated just after engine starting to be heated to the temperatures sufficient for the catalyst to function optimally within seconds, thereby safely purifying all of the emissions from cars.
