摘要： Embodiments for heating an emission control device are provided. In one example, a method for a turbocharged engine comprises during an engine cold-start, delivering boosted air from downstream of a compressor into a wastegate duct coupled across a turbine and exothermically reacting a reductant with the boosted air upstream of an exhaust emission control device. In this way, boosted air may be used to initiate an exothermic reaction to heat the device.

摘要： Methods and systems are provided for heating a catalyst during engine cold-start conditions. One example embodiment uses positive valve overlap to drive a boosted blow-through airflow through the cylinders of an engine. Fuel is injected with the blow-through airflow during the valve overlap, and also injected into engine cylinders outside the valve overlap. The catalyst is heated by the resulting exothermic reaction of the blow-through airflow with the combustion products and the injected fuel in the exhaust manifold.

摘要： Systems and methods for reducing NOx emissions using a branched exhaust system with a first and second turbine including an emission-control device containing a zeolite, are described. In one example approach, a method comprises: during a first duration when exhaust temperature is below a first temperature threshold, directing exhaust gas through the second turbine and the emission-control device, and adjusting the second turbine to control intake boost; and during a second duration following the first, directing exhaust gas through the first turbine, and adjusting the first turbine to control intake boost. The emission-control device may be purged when exhaust temperature is above a second temperature threshold higher than the first temperature threshold, where during the second duration exhaust gas does not flow through the emission-control device.

摘要： A system and a method for effective NOx and particulate matter control in a diesel or other lean burn internal combustion engine is presented. The system includes a urea-based SCR catalyst having an oxidation catalyst coupled upstream of it and a particulate filter coupled downstream of the SCR catalyst. The particulate filter regeneration method teaches controlling operating conditions to bring the particulate filter temperature in the range where exothermic reaction between hydrocarbon and oxygen occurs. Once this is accomplished, extra hydrocarbons are injected into the exhaust gas entering the particulate filter where they combust and the resulting exotherm regenerates the filter. This method achieves effective particulate matter control while eliminating the risk of thermal damage to the upstream devices and minimizing regeneration fuel economy penalty.

摘要： An assembly is disclosed for reducing emissions produced by an internal combustion engine of a motor vehicle. The assembly comprises a catalyst, a battery, an alternator, and a control relay. The catalyst is disposed in a catalytic converter downstream of the engine and receives exhaust gases therefrom. The catalyst is disposed proximate a substrate of the catalytic converter, which heats the catalyst when electrical power is supplied to the substrate. The alternator is in selective electrical communication with the battery and with the substrate, and is electrically connectable to the substrate to supply power thereto when the engine is operating. The control relay puts the alternator in electrical communication with either the battery, or with the substrate when the engine is started. A voltage regulator is also preferably provided in communication with the battery and with the alternator.
