    摘要： An inlet chamber 40 and outlet chamber 50 for exhaust gas are integrated as an inflow/outflow section 80, and a first post treatment device 10 equipped with a DPF 13 at its central portion and second post-treatment device 20 equipped with a urea DeNOx catalyst 23 on its outer periphery side are integrated as a catalyst installation section 70. The catalyst installation section 70, the inflow/outflow section 80, and a communication chamber forming section 30 are provided separately and detachably from one another, and the catalyst installation section 70 is made installable in a reversible manner. As a result, by reversing the catalyst installation section 70, it is possible to easily reverse the DPF 13 without having to extract it from the central part. Further, since the urea DeNOx catalyst 23 is reversed simultaneously, it is possible to change the direction in which the exhaust gas flows therein, thereby enabling to prevent unbalanced deterioration of the urea DeNOx catalyst 23.

    摘要： The present invention involves thermal management of an integrated emission reduction system for the removal of particulate matter (PM) and nitrogen oxides (NOx) from diesel engine exhaust streams. The inventive integrated emission reduction system may include a diesel particulate filter (DPF), a heat source for adjusting the temperature of the exhaust stream entering the DPF, at least one selective catalytic reducer of NOx, a heat exchanger for adjusting the temperature of the exhaust stream entering the NOx reducer, and a computing device for monitoring the temperature and/or pressure of the exhaust stream entering the DPF and the NOx reducer, and for controlling the operation of the heat exchanger and heat source, thereby improving the efficiency of the DPF and the NOx reducer.

    摘要： A method for operating an internal combustion engine includes combusting fuel and air within a combustion chamber of an internal combustion engine, thereby forming an exhaust gas, passing the exhaust gas out of the combustion chamber, and performing a startup procedure, the startup procedure including passing the exhaust gas from the combustion chamber through a first aftertreatment system to a pollutant capture unit, capturing criteria pollutants of the exhaust gas with the pollutant capture unit, and heating the first aftertreatment system to a first activation temperature. Subsequent to heating the first aftertreatment system to the first activation temperature a secondary procedure is performed including passing the exhaust gas from the combustion chamber directly to a second aftertreatment system bypassing the pollutant capture unit to heat the second aftertreatment system to a second activation temperature. Subsequently, exhaust gas is passed through the pollutant capture unit to desorb captured criteria pollutants.
