摘要： An exhaust gas processing device for an engine, capable of securely warming a combustion catalyst, is provided. A combustion catalyst burning gas is produced when a warming end condition for the combustion catalyst is established, which signifies the establishment of either one of a first condition or a second condition. In the first condition, an inlet temperature of a combustion catalyst is equal to or higher than an activation requirement temperature of the combustion catalyst, and further, an outlet temperature of the combustion catalyst is equal to or higher than an activation confirmation temperature of the combustion catalyst in excess of the inlet temperature of the combustion catalyst. In the second condition, the outlet temperature of the combustion catalyst exceeds a warming confirmation temperature of the combustion catalyst that is set to be higher as an engine speed is lower, for a predetermined period of time.

摘要： A proportional heater controls a diesel powered electrical generator with a diesel particulate filter (DPF). A proportional control is applied to the heater based upon exhaust temperature. The heater heats exhaust gas to a regeneration temperature to remove soot and sulphur from the processed gas when the diesel fuel has a sulphur content exceeding 1,000 ppm. The heater is supplied power via SCRs to reduce electromagnetic and radio frequency interference. A manual override permits the operator to set a temperature setpoint, force the heater to meet a certain temperature and establish a load bank for diesel engine electrical generator set.

摘要： A method of heating an exhaust gas in an exhaust aftertreatment system including a Diesel Oxidation Catalyst (DOC) and a diesel particulate filter (DPF) is provided. The method includes heating the exhaust gas to a predetermined temperature to increase NO2 generation in the DOC when the DPF is not actively regenerated, and heating the exhaust gas to reduce an exhaust temperature gradient when the DPF is actively regenerated. The exhaust temperature gradient is reduced by providing more heat proximate a wall of an exhaust conduit and less heat proximate a center of the exhaust conduit.
