A method for injection reductant into an exhaust gas and for evaporating and decomposing the reductant at an elevated temperature includes providing an exhaust pipe having an interior surface and disposing the pipe in fluid communication with and upstream of a catalyst. The method includes the steps of disposing an internal cone within the pipe generally parallel to the pipe, mounting an injector to the exterior of the pipe in fluid communication with the cone, injecting the reductant into the cone, and directing the exhaust gas in a passage between the interior surface of the pipe and the cone. The exhaust gas is directed within the cone. The flow of exhaust gas has an elevated temperature compared to an ambient. A further step includes creating a drag force on the injected reductant to increase travel time of the injected reductant from the injector to the catalyst.

A device and method for catalytic reduction of NOx in gaseous products of combustion by directing the products of combustion through a particulate filter () and then into a mixing zone () through separate flow passages () at respective velocities greater than that at which products of combustion leave the filter, by causing an injector () to introduce urea solution through a nozzle () aimed toward the mixing zone along a slant direction () to, and across, flow entering the mixing zone through a first () of the separate flow passages and ultimately toward a far wall () of the mixing zone relative to the nozzle while directing exhaust flow entering the mixing zone through a second () of the separate flow passages to enter the mixing zone between the first flow passage and far wall, and by directing flow leaving the mixing zone through an SCR catalyst ().

A system for use in injection of a liquid reductant into an exhaust gas () and for evaporating the liquid reductant includes an exhaust pipe () having an interior area (). Exhaust gas () flows through the interior area () of the exhaust pipe (), the flow of exhaust gas being at an elevated temperature from the ambient. A deflection plate () has a non-planar shape and is disposed within the interior area () of the exhaust pipe (). An injector () injects the liquid reductant into the exhaust pipe () and directs the liquid reductant at the deflection plate ().

A urea supply conduit () has a wall of good thermal conductivity. Urea solution in liquid phase is sucked out of a tank () through conduit () and delivered to a point of use () in an engine exhaust after-treatment system () through which products of combustion are conveyed from engine combustion chambers () to atmosphere. Liquid engine coolant is circulated through a coolant conduit () that has a wall of good thermal conductivity placed side-by-side and in physical association with the urea supply conduit wall to form a thermal conduction path for heat transfer between coolant in the coolant conduit and urea in the urea supply conduit, more quickly thawing any frozen urea.

An exhaust valve actuation system () for initiating a regeneration event at a diesel particulate filter () includes an engine control module () associated with an engine (). A plurality of exhaust valves () correspond to a plurality of engine cylinders (C-C). When either a predetermined amount of back pressure or a predetermined temperature, or both, are communicated to the engine control module (), the engine control module actuates at least one exhaust valve () to open. Gas or gas-fuel mixture is compressed and heated inside of the cylinder (C) corresponding to the opened exhaust valve (). At least one exhaust valve () is not opened by the engine control module (), which permits combustion inside the corresponding cylinder (C).

An exhaust gas aftertreatment system () for a vehicle having an engine () includes a fluid passageway () extending from the engine to an ambient () for fluidly communicating exhaust gas (F). A diesel particulate filter () is disposed on the fluid passageway () downstream of the engine (). At least one exhaust throttle valve (A-D) is located downstream of the engine () on the fluid passageway (). When the exhaust throttle valve (A-D) is actuated, the valve obstructs the flow of exhaust gas (F) and increases the temperature of the exhaust gas. The heated exhaust gas (F) causes regeneration at the diesel particulate filter ().

A control system for an engine having an in-cylinder pressure sensor and a selective catalytic reduction device comprises an electronic control module and an in-cylinder pressure sensor. The electronic control module has a processor and a memory. The in-cylinder pressure sensor is disposed in fluid communication with a cylinder of an engine. The incylinder pressure sensor is disposed in communication with the electronic control module. The in-cylinder pressure sensor generates an output indicative of a pressure within the cylinder of the engine. The processor of the electronic control module is programmed to generate an estimate of an amount of NOx produced during combustion, and calculate an amount of reductant required to react with the NOx to limit NOx emissions to a predetermined level.
