Abstract: An internal combustion engine (1) has an electric heating catalyst (5) in an exhaust passage (2). When it is detected that a door has been opened, the electric heating catalyst (5) is preheated. If power of an engine controller (8) is lost during the preheating, information on an estimated temperature, which is stored in the engine controller (8), is lost. The engine controller (8) forbids energization of the electric heating catalyst (5) until a cooling period necessary for temperature of the electric heating catalyst (5) to fall elapses after recovery of the power of the engine controller (8). After the cooling period elapses, the preheating is started again.

Abstract: An assembly and method for reducing nitrogen oxides, carbon monoxide, hydrocarbons and hydrogen gas in exhausts of internal combustion engines and simultaneously generating electrical power, wherein the exhaust is acted upon in a first stage catalytic converter and is at least in part passed through a thermoelectric generator for production of electrical power. The exhausts are thereafter directed to a second stage catalytic converter.

Abstract: Some embodiments relate to a catalytic assembly for an engine. The catalytic assembly includes a cooling housing that receives a coolant (e.g., seawater). A catalyst housing is disposed within the cooling housing such that the coolant flows between the catalyst housing and the cooling housing. A catalyst substrate is positioned within the catalyst housing such that exhaust gases from the engine flows through the catalyst substrate. The catalyst substrate serves to covert harmful emissions found in the exhaust gases to less harmful emissions. The catalyst housing includes a first fitting and cooling housing includes a second fitting that mates with the first fitting to prevent rotation of the catalyst housing relative to the cooling housing.
