摘要： An integrated internal combustion engine control system in combination with an automotive emission control system, comprises an exhaust-gas recirculation valve (EGR valve) employed in an EGR system. A target EGR amount is calculated as a function of an intake-air flow rate measured by an air-flow meter and a target EGR rate based on engine operating conditions such as engine speed and engine load. The opening of the EGR valve is adjusted by a command from a control unit so that the target EGR amount is attained. The target EGR rate is preferably calculated depending on an intake pressure as well as the engine speed and the engine load. In combination with the above-mentioned EGR control, a throttle valve disposed in the induction system is effectively controlled in response to an actual valve lift of the EGR valve and a differential pressure between an exhaust pressure and the intake pressure. A fuel-injection amount is accurately controlled in consideration of a variation of an excess-air factor. To compensate a phase lag a predetermined advance processing is made to a signal from a typical air-flow meter, and then the advance-processed signal is effectively signal-processed to invert a reverse-flow component in the output signal.

摘要： An internal combustion engine for a motor vehicle is described which is provided with an injection valve with which fuel can be injected directly into the combustion chamber either in a first mode of operation during a compression phase or in a second mode of operation during an induction phase. Furthermore, the engine is provided with means for feeding back the exhaust gas into the combustion chamber as well as with a control apparatus for controlling (open loop and/or closed loop) the quantity of the fed back exhaust gas. According to the invention, the quantity of the exhaust gas, which is fed back into the combustion chamber, can be controlled (open loop and/or closed loop) differently in the two modes of operation.

摘要： The present invention provides a method and apparatus for controlling an internal combustion engine. The engine includes a variable flow exhaust gas recirculation (EGR) system. The method includes providing a variable geometry turbocharger (VGT) in communication with the EGR system for controlling exhaust gas recirculation. The geometry of the VGT is varied by adjustably controlling a rotary electric actuator (REA) operatively connected to the VGT. A position-adjustable proportional flow EGR valve is adjusted by adjustably controlling a second rotary electric actuator (REA) operatively connected to the position-adjustable proportional flow valve.
