LOW NOX COMBUSTION METHOD COMBINING CATALYST COMBUSTION AND SWIRL GENERATION OF CATALYST LAYER AND COMBUSTION ENGINE THEREOF

摘要

PURPOSE: A low NOx combustion method combining catalyst combustion and swirl generation of catalyst layer and a combustion engine thereof are provided to reduce NOx generated in a high load combustion engine by decreasing the temperature of flames to a low temperature not to generate thermal NOx by employing the catalyst combustion. CONSTITUTION: A low NOx combustion method in which catalyst combustion is combined with swirl generation of a catalyst layer includes the steps of burning a mixture(1) partially in a catalyst layer(2) by a catalyst surface reaction for generating lean mixture with the heat generated by catalyst combustion to increase the burning speed of the mixture and generating swirl in the mixture by a rear wake for holding flames, and stabling burning the heated lean burn mixer(1) at a burning speed raised in a flame burning chamber(3) mounted at a rear part of the catalyst layer to discharge exhaust gas(4) with reduced NOx.
