原始语种摘要: A chemically heated and electrically initiated catalyst in combination with a traditional converter can achieve the Low and Ultra Low Emission Vehicle (ULEV) standards. Experiments are conducted to investigate the impact of the various heating strategies and the system design parameters aiming emission decrease. An attempt is also made to reduce the cold-start emission of a multi-cylinder SI engine using Chemically Heated Catalytic (CHC) converter of a different volume of CHC filled with different oxides acting as a catalyst. It is found that CHC reduces cold-start hydrocarbon and carbon monoxide emission when used with the existing catalytic converter. The maximum CO and HC reduction is achieved with the catalytic converter with copper oxide as a catalyst over nickel oxides filled with...
