Abstract
An exhaust gas purifier for a diesel engine is positioned in the middle of an inlet system for supplying air to a combustion chamber. The exhaust gas purifier includes an HC (hydrocarbon) supply source, and a zeolite catalyst converter, which is activated by the hydrocarbon as a reduction agent to crack NOx (oxides of nitrogen) in the exhaust gas, for thereby purifying the exhaust gas.
