摘要： The present invention is based on the application of heating resistors by a temperature regulation circuit in certain points of the catalyzer so that this comes into operation in the least time possible, reducing most of the amount of low molecular stability or environmentally harmful substances. Likewise, little tumult are added to each monolith duct to raise exhaust gas turbulence and increase the contact between the reduction and oxidation agent, whether it be platinum, palladium and rhodium.

摘要： An apparatus for reactivating a sulfur poisoned oxidation catalyst operating in the exhaust of a lean burn, methane source (as in natural gas) fueled combustion device as in an engine. The reactivation includes desulfation of the poisoned catalyst through the use of a CO supplementation apparatus in communication with the control unit that is adapted to supplement the CO content in the exhaust reaching the catalyst, while avoiding an overall rich exhaust atmosphere at the catalyst. An example includes the added supply of hydrocarbons to one or more, preferably less than all, of the lean burn engine's combustion chambers such as by an ECU controlled extra supply of NG (e.g., CNG) to some of the combustion chambers. Also featured is a method for desulfation of an oxidation catalyst of a lean burn CNG engine by supplying excess CO to the exhaust reaching the catalyst while retaining an overall lean state, and a method of assembling an apparatus for reactivating a sulfur deactivated lean burn NO engine catalyst by assembling a CO supplementation apparatus with a control unit.

摘要： An engine radiator cooling fluid circuit and an exhaust gas intercooler (EGI) radiator cooling fluid circuit are fluidically in parallel with one another. The engine radiator cooling fluid circuit extends from the radiator to an engine associated with a vehicle or a stationary system such as a CHP system. The EGI radiator cooling fluid circuit extends from a radiator to an EGI that cools exhaust gas as it flows through an exhaust conduit that extends from a first catalytic converter to a second catalytic converter. The radiator cooling fluid circuits can share a common radiator coil or each radiator cooling fluid circuit can be associated with a respective radiator coil in the radiator. A gas particulate filter can be coupled to the exhaust conduit or the second catalytic converter. An air-driven exhaust gas ejector (EGE) such as an engine charger compressor injects air into an inlet port in the exhaust conduit.

摘要： An exhaust gas control system of an internal combustion engine includes an EGR device, a three-way catalyst, and an electronic control unit. The electronic control unit is configured to control the air-fuel ratio of the exhaust gas flowing into the three-way catalyst such that the air-fuel ratio when the electronic control unit executes EGR control during execution of fuel cut control and then executes the enrichment processing after the execution of the fuel cut control ends to be a higher air-fuel ratio in a range of the rich air-fuel ratio compared to the air-fuel ratio when the EGR control is not executed during the execution of the fuel cut control.

摘要： Systems and methods of reducing the emissions of vehicles having a spark ignited internal combustion engine are provided. When the exhaust temperature is less than a set point temperature, the oxygen concentration of the exhaust is increased as the exhaust passes from a first stage catalytic converter to a second stage catalytic converter. The increased oxygen content of the exhaust improves the removal efficiency of carbon monoxide and/or hydrocarbons at the second stage catalytic converter without (or with minimal) reforming nitrogen oxide compounds. The oxygen concentration of the exhaust is not increased when the exhaust temperature is greater than the set point temperature.

摘要： A control device of an internal combustion engine which is provided with an exhaust purification catalyst is provided with a downstream side air-fuel ratio sensor, a feed control means for controlling the fuel feed amount so that the air-fuel ratio of the exhaust gas becomes a target air-fuel ratio, and an excess/deficiency estimating means which estimates an oxygen excess/deficiency in the exhaust gas. The target air-fuel ratio is switched to a lean air-fuel ratio when the output air-fuel ratio of the downstream side air-fuel ratio sensor becomes a rich air-fuel ratio and is switched to the rich air-fuel ratio when the stored amount of oxygen of the exhaust purification catalyst after this becomes a switching reference amount or more. An absolute value of cumulative oxygen excess/deficiency at a time period during which the target air-fuel ratio is made the lean air-fuel ratio and an absolute value of cumulative oxygen excess/deficiency at a time period during which the target air-fuel ratio is made the rich air-fuel ratio are used as the basis to correct the target air-fuel ratio etc. so that the difference of these absolute values becomes small.

摘要： A wash coat is formed by combining platinum group metals (PGM) and an adhesive with a mixture of catalyst support materials according to the relationship (α)RE-Ce—ZrO2+(β)CZMLA+(1−α−β)RE-Al2O3. The RE-Ce—ZrO2 is a commercial material of rare earth elements stabilized ceria zirconia having a weight ratio (α) ranging from 0 to about 0.7; CZMLA is a catalyst support material comprising a core support powder coated with a solid solution and has a weight ratio (β) ranging from about 0.2 to about 1 such that (α+β)≦1. RE-Al2O3 is rare earth element stabilized alumina having a weight ratio equal to (1−α−β). The wash coat exhibits a lower activation temperature compared with traditional wash coat formulations by at least 50° C. This wash coat also requires less RE-Ce—ZrO2 oxide and/or less PGM in the formulation for use as an emission control catalyst for gasoline and diesel engines.
