  • Internal EGR for an internal combustion engine
    Patent number: 7213553
    Abstract: An exhaust gas recirculation (EGR) system for use in a four-stroke, internal combustion, compression-ignition engine having at least one engine cylinder, at east one combustion chamber, at least one intake valve and a crankshaft. The EGR system includes at least one exhaust gas intake valve that is opened during at least a portion of an engine intake stroke when the exhaust gas pressure is greater than the pressure of gas in the combustion chamber, thus allowing exhaust gas to flow into the combustion chamber to establish internal EGR. A cam-operated intake rocker arm assembly has the form of both a first class lever and a second class lever. The first class lever directly communicates motion of the intake rocker arm assembly to open the intake valve, and the second class lever communicates motion of the intake rocker arm assembly through a hydraulic transfer assembly to open the exhaust gas intake valve.

  • System and method for reducing compression ignition engine emissions
    Patent number: 7212908
    Abstract: A method of reducing nitrogen oxides (NOx) and particulate matter (PM) in compression ignition engine emissions. The method includes monitoring at least one engine sensor that generates a signal in response to at least one engine operating condition, and adjusting at least one engine control parameter in response to the signal such that in-cylinder spacial distribution of equivalence ratio and temperature is substantially maintained to an operating region. The operating region corresponds to a set of equivalence ratio with respect to temperature values that are substantially outside regions supportive of NOx and PM formation. The temperature values are greater than 1650 K, and the equivalence ratio values are greater than 0.5.
