Turbocharged engine water vapor ingestion control techniques determine a dew point of a charge air cooler (CAC) in an induction system of the engine based on measured humidity and temperature of a mixture of (i) air drawn into the induction system and (ii) exhaust gas produced by the engine that is cooled and recirculated by a low pressure cooled exhaust gas recirculation (LPCEGR) system of the engine back into the induction system. When the mixture temperature is less than the CAC dew point, a condensate accumulation in the CAC is determined. When the CAC condensate accumulation does not satisfy a set of one or more thresholds, the mixture temperature is increased. When the CAC condensate accumulation satisfies the set of one or more thresholds, an amount of the exhaust gas that is cooled and recirculated by the LPCEGR system is decreased until the mixture temperature meets the CAC dew point.

An apparatus for removing moisture from exhaust gas is disclosed. The apparatus includes an inner chamber including an inner exhaust port, configured to discharge the exhaust gas flowing along a chimney, and an outer chamber, surrounding the inner chamber and including an outer exhaust port configured to discharge the exhaust gas discharged from the inner exhaust port, wherein an exhaust path is defined between the inner chamber and the outer chamber such that the exhaust gas discharged from the inner exhaust port flows along the exhaust path and is discharged through the outer exhaust port.

Operating a machine system for co-production of electrical power and filtered potable water includes operating an electrical generator by way of rotation of an engine output shaft to produce electrical power, and collecting water condensed from cooled treated exhaust from the engine for delivery to an outgoing water conduit.

The heating device has: a first gas-liquid heat exchanger, which is designed to be flown through by at least part of the exhaust gases flowing along the exhaust duct; a second liquid-liquid heat exchanger, which is designed to heat the water-based operator liquid contained in the tank; and a hydraulic circuit, which is designed to send round an exchange fluid through the first heat exchanger to transfer the heat from the exhaust gases to the exchange fluid and through the second heat exchanger to transfer the heat from the exchange fluid to the water-based operator liquid contained in the tank.

A method for mitigating against failure of a particulate matter sensor of an automobile vehicle includes: determining if a key-off event is present, identifying an engine is off in a vehicle after-run mode; defining when local environmental conditions are outside of mechanical limits of a particulate matter (PM) sensor; identifying input values to reverse the local environmental conditions of the PM sensor; and controlling operation of a heating element of the PM sensor to achieve the input values to reverse the local environmental conditions during the vehicle after-run mode.

An aftertreatment module is disclosed. The aftertreatment module may include a housing and a mounting plate within the housing that forms an inlet chamber and an outlet chamber. The aftertreatment module may include an inlet for exhaust gas from a combustion engine to flow into the inlet chamber and an outlet through a top plate of the housing for the exhaust gas to flow from the outlet chamber, wherein the outlet comprises a plurality of perforations. The aftertreatment module may include an outlet sensor mounted on the outlet to obtain information relating to the exhaust gas as the exhaust gas flows from the outlet chamber and a set of catalysts mounted to the mounting plate to treat the exhaust gas as the exhaust gas flows from the inlet chamber to the outlet chamber. The aftertreatment module may include a drain port through a side plate of the housing.
