Did you know?
WebA heat-up catalyst is a very common option for raising diesel engine exhaust temperature and enthalpy by catalytic combustion of fuel. The heat-up catalyst is typically a diesel oxidation catalyst (DOC) to which fuel is supplied via the in-cylinder fuel injectors or a separate dedicated injector mounted in the exhaust system. WebThe reaction mechanism over the diesel oxidation catalyst is explained by the presence of active catalytic sites on the surface of the catalyst carrier, that have the ability to adsorb oxygen. In general, the catalytic …
