A burner-based exhaust gas generation system, for producing exhaust gas, typically for use in testing exhaust system devices. Post-burner exhaust gas is recirculated back to a main exhaust line, and used for purposes such as cooling or enhancing the burner output.

Use of recirculated exhaust gas in a burner-based exhaust generation system for reduced fuel consumption and for cooling

A method of using a burner-based system to produce diesel exhaust gas that contains particulate matter of a desired composition, to simulate the PM matter in exhaust produced by a production-type diesel internal combustion engine.

Method for producing diesel exhaust with particulate material for testing diesel engine aftertreatment devices

An emission control system for reducing NOin the exhaust of a diesel engine. A partial oxidation system receives diesel fuel from the engine's fuel tank and partially oxidizes the diesel fuel into hydrogen. The hydrogen is then introduced into the main exhaust line and the hydrogen-enhanced exhaust is delivered to a hydrogen selective catalytic reduction unit, which uses the hydrogen to convert the NOto nitrogen.

[object Object]

A method for testing one or more test components including providing a non-engine based test system including a combustor in fluid communication with the one or more test components; supplying air and fuel to the combustor at an air to fuel ratio (AFR) and under feed conditions effective to produce a feedstream flowpath, wherein the fuel includes one or more alternative fuel which is gaseous at ambient conditions including atmospheric pressure and a temperature of about 20&#xb0; C. or higher, the supplying air and fuel including feeding the one or more alternative fuel to a pressure regulator to produce one or more pressure regulated alternative fuel and feeding the one or more pressure regulated alternative fuel to the combustor; combusting at least a portion of fuel in the feedstream flowpath under combustion conditions effective to produce an exhaust product including one or more alternative fuel exhaust; and, exposing the one or more test components to the exhaust product under test conditions effective to produce one or more treated components.
