Catalytic microchannel reformer


An apparatus and method for enhancing the yield and purity of hydrogen when reforming hydrocarbons is disclosed in one embodiment of the invention as including receiving a hydrocarbon feedstock fuel (e.g., methane, vaporized methanol, natural gas, vaporized diesel, etc.) and steam at a reaction zone and reacting the hydrocarbon feedstock fuel and steam in the presence of a catalyst to produce hydrogen gas. The hydrogen gas is selectively removed from the reaction zone while the reaction is occurring by selectively diffusing the hydrogen gas through a porous ceramic membrane.

Method and system for diagnosing common rail diesel engine


Disclosed are a method and a system for diagnosing a common rail diesel engine. The method for diagnosing a common rail diesel engine may include setting a time when a pressure of a common rail becomes a first set pressure to a diagnosis start time and neglecting a state of the common rail until the pressure of the common rail decreases from the first set pressure to a second set pressure which is a diagnosis end pressure, verifying a time when the pressure of the common rail becomes the second set pressure and determining the time as a diagnosis end time when the pressure of the common rail becomes the second set pressure, calculating a diagnosis time as an elapsed time from the diagnosis start time to the diagnose end time, and diagnosing that fuel leaks from the common rail when the diagnosis time is shorter than a diagnosis set time by comparing the diagnosis time with the diagnosis set time..

Apparatus and controlling regeneration in exhaust emission control device


A method and an apparatus for controlling regeneration of an exhaust emission control device in which a diesel particulate filter (dpf) may be installed at a back stage of a reducing agent supply apparatus may include measuring temperature of a front stage of the dpf at the time of supplying a reducing agent, comparing a temperature value measured at the front stage of the dpf with a temperature modeling value of the front stage of the dpf, and controlling the regeneration of the dpf by comparing a difference between the temperature value and the temperature modeling value with a reference variation.. .

Method for detecting abnormally frequent diesel particulate filter regeneration, engine and exhaust aftertreatment system, and warning system and method


A method is provided for detecting abnormally frequent diesel particulate filter (dpf) regeneration. The method includes measuring a pressure drop across the dpf and using the measured pressure drop to calculate a pressure drop based soot load estimate, calculating soot output from an engine model and using the calculated soot output to calculate an emissions based soot load estimate, comparing the pressure drop based soot load estimate with the emissions based soot load estimate, and providing a warning if a difference between the pressure drop based soot load estimate and the emissions based soot load estimate exceeds a predetermined.
