    摘要： The present invention provides an exhaust cooler mounted to a tailpipe for receiving exhaust gas. The exhaust cooler includes a jet pump connectable to the tailpipe and a nozzle connectable to the tailpipe. The nozzle defines a nozzle opening between the tailpipe and the jet pump for communicating the exhaust gas from the tailpipe to the jet pump. A first member is included that is moveable between a closed position and an open position, the open position defining a first opening between the tailpipe and the jet pump for communicating the exhaust gas from the tailpipe to the jet pump.

    摘要： Exhaust flow from an internal combustion engine is divided in a predetermined ratio between two adsorber catalysts arranged in parallel during lean operation. A regeneration cycle time is predetermined and regeneration is accomplished by injecting hydrocarbons into a catalyst leg having a reduced exhaust flow. Upon regeneration of the catalyst, the exhaust gas flow distribution is reversed and the opposite catalyst is regenerated while the regenerated catalyst bears the brunt of the exhaust flow. The exhaust flow then reverts to a normal (e.g. 50—50) flow distribution until another regeneration cycle is warranted. A catalytic soot filter placed upstream of each adsorber is also regenerated by hydrocarbon injection. The addition of the catalytic soot filter provides more time and surface area for the hydrocarbon to react with the oxygen. Some of the diesel fuel is reformulated into hydrogen and carbon monoxide for superior regeneration.

    摘要： An assembly for mixing liquid within a gas flow includes a hollow conduit that is configured for containing a flow of gas and liquid droplets. The assembly also includes multiple spaced blades and an impingement element. Each of the blades is operatively connected to and extends from the impingement element and is connected to an inner wall of the conduit. The impingement element is upstream of the blades in the flow of gas. The impingement element and the blades are configured to create a preferred distribution of the liquid droplets within the gas flow downstream of the blades within the conduit.

    摘要： An exhaust gas treatment system for an internal combustion engine is provided and includes an exhaust gas conduit, a hydrocarbon supply, a particulate filter (“PF”), at least one sensor, a first temperature sensor, a second temperature sensor, and a control module. The PF is in fluid communication with the exhaust gas conduit and has a filter structure for removal of particulates in the exhaust gas. The filter structure has an innermost region and an outermost region. The PF is selectively regenerated during operation of the internal combustion engine. The PF has a stratified temperature structure that causes the particulates trapped at the innermost region of the PF burn off before the particulates trapped in the outermost region of the PF during regeneration. The control module has a memory with an infinite stage temperature control curve stored thereon.
