An end can assembly for an engine exhaust aftertreatment canister comprises an end can formed from an end plate and a wall extending from a periphery of the end plate, the end plate and the wall having a first cutaway portion formed therein. A pipe is provided in the first cutaway portion and attached to the end can around the first cutaway portion to form a seal with the end can, the pipe having at least one opening provided therein which opens into an interior of the end can assembly. A bracket, comprising a plate and a shoulder extending at an angle from the plate, is attached to the end plate and to the wall, the shoulder having a second cutaway portion formed therein which is shaped to receive the pipe whereby the shoulder abuts the pipe and provides structural support to the pipe and end can.

A water drainage assembly for an aftertreatment system comprises a first tube structured to be coupled to an outlet conduit of the aftertreatment system and has a first cross-sectional width. A second tube is disposed radially around the first tube. A first end of the second tube is coupled to a radially outer surface of the first tube. A portion of the second tube has a second cross-sectional width larger than the first cross-sectional width such that a volume is defined between the first and second tubes. A drain port is defined in the second tube proximate to the first end. The assembly is structured such that water flowing into the water drainage assembly flows into the volume defined between the first tube and the second tube and is expelled therefrom via the drain port.

An exhaust gas aftertreatment system for a diesel-engined vehicle, which system comprising a NO.sub.x Storage Catalyst (NSC) followed in a downstream direction by a Catalysed Soot Filter (CSF), wherein the CSF comprises an oxidative catalyst comprising a palladium-rich weight ratio of platinum and palladium.

When an amount of particulate matter (PM) collected by a gasoline particulate filter (GPF) reaches a predetermined amount, a central processing unit (CPU) executes a regeneration process for regenerating the GPF. That is, the CPU stops supply of fuel to any one of cylinders #1 to #4, while increasing an amount of fuel supplied to remaining cylinders. When a temperature of a three-way catalyst becomes equal to or higher than a first temperature, the CPU increases an injection amount to lower a temperature of exhaust gas. When the temperature of the three-way catalyst becomes equal to or higher than the first temperature during the execution of the regeneration process, the CPU does not increase the injection amount.

An exemplary vehicle exhaust system includes, among other things, a housing defining a fluid chamber and at least one pressure sensor positioned within the fluid chamber. The housing has a fluid inlet configured to receive fluid from a fluid supply and a fluid outlet. A heater heats fluid supplied from the fluid supply such that heated fluid can be injected into a vehicle exhaust component via the fluid outlet. A controller is configured to receive pressure data from the at least one pressure sensor and to determine optimal timing for dosing of the vehicle exhaust component based on the pressure data.

A connection unit for an exhaust gas heater in an exhaust gas system of a combustion engine includes an electrically conducting connection element, elongated in the direction of a connection element longitudinal axis (L). The connection element has an inner connection region for connection to a heating conductor and an outer connection region for connection to an electrical supply. A carrier arrangement surrounds the connection element and an insulating arrangement insulates the connection element with respect to the carrier arrangement.

An exhaust-gas purification system of an internal combustion engine includes an electrically heated catalytic device and a three-way catalytic device. The electrically heated catalytic device includes a first honeycomb base having a large number of honeycomb passages and a first catalyst component that is supported on, by a predetermined thin-film treatment, surfaces that define the honeycomb passages and that contains one or more types of noble metals. The three-way catalytic device includes a second honeycomb base having a large number of honeycomb passages and a second catalyst component that is supported on surfaces defining the honeycomb passages and that contains one or more types of noble metals. The total noble metal content per unit volume of the second honeycomb base is higher than the total noble metal content per unit volume of the first honeycomb base.

A control system is provided for a diesel particulate filter (DPF) system of a diesel engine configured for operation in an off-highway vehicle. The control system includes a controller configured to receive a signal corresponding to a fill state of the DPF being at or above a first threshold. The controller is configured to selectively induce a parasitic load on the diesel engine to increase an operating temperature of the engine in response to receiving the signal.

Separation of carbon dioxide from the exhaust of an internal combustion engine, the production of hydrogen from water, and reformation of carbon dioxide and hydrogen into relatively high-octane fuel components.

A device for capturing in-port ship exhaust gases is designed to be connected to a ship when the ship has at least one funnel that serves as an outlet for exhaust gases. The device includes at least one collection device, including a hood designed to connect to the funnel at the exhaust outlet so as to collect the exhaust gases coming out of the funnel, a handling unit designed to move the collection device and position it at the exhaust outlet, a first constraint configured to interconnect or disconnect the collection device and the handling unit by command so as to create a handling configuration in which the collection device and the handling unit are interconnected by the first constraint and can be moved as one, and a collection configuration in which the collection device collects the exhaust gases and the connection achieved by the first constraint is released.
