    摘要: A microprocessor-based controller is provided for generated heat in at various locations in an exhaust system of an engine by changing the heat generation technique utilized. In one case, some cylinder air-fuel ratios are modulated between stoichiometry and rich, while others are modulated between stoichiometry and lean. Another approach operates some cylinder lean, while others are modulated between a first rich, and a second, less rich, value. Further, compensation based on engine airflow is also provided. Finally, various methods are described for temperature control and for controlling modulation of air-fuel ratio.

    摘要: A system for trapping liquid exhaust during a cold start of an internal combustion engine is provided. As one example, a system includes, an exhaust inlet, an exchange area fluidly coupled downstream of said exhaust inlet, a trap coupled to said exchange area having a liquid exhaust chamber for collection of liquid exhaust, and a catalytic converter fluidly coupled downstream to said exchange area. In another example, a method includes condensing, at least partly, exhaust from the engine in an exchange area in an exhaust system into liquid exhaust, collecting liquid exhaust into a trap disposed in the exchange area, and evaporating the liquid exhaust into the exchange area after an evaporation temperature is reached in the trap.
