Abstract
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.
