摘要： Methods and systems are provided for reducing turbo lag in a boosted engine. A boost reservoir coupled to the engine may be charged with compressed intake air and/or combusted exhaust gas. The pressurized charge may then be discharged during a tip-in to either the intake or the exhaust manifold.

摘要： Embodiments for controlling cylinder air flow are provided. In one example, a method for controlling airflow into a cylinder of an engine comprises, if a previous cylinder airflow is different than a desired cylinder airflow, allocating flow into an intake manifold between a throttle and an EGR valve to provide the desired cylinder airflow while maintaining a desired EGR amount in the cylinder. In this way, transient air flow requests may be met without delay while maintaining desired cylinder EGR amounts.

摘要： An exhaust gas recirculation systems directs exhaust gasses from an exhaust manifold to an intake manifold of an internal combustion engine. The exhaust gasses travel from the exhaust manifold, first passing through a flow control valve and then through a measuring orifice before entering the intake manifold. Pressure upstream of the orifice is used, along with correction pressure downstream of the orifice, to measure and control exhaust gas flow. Further, manifold pressure is determined from downstream pressure and the used along with the measured exhaust gas flow to calculated a cylinder air charge amount.

摘要： An EGR system using pressure-based feedback control includes an actuator for moving an EGR valve between a closed position and an open position, and a position sensor for detecting the position of the EGR valve and generating a position output signal. A processing circuit receives the position output signal and transmits electrical control signals to energize the actuator and move the EGR valve. A controller includes control logic operative to determine the position for the EGR valve using open loop control during transient behavior and closed loop control for steady state accuracy.

摘要： An exhaust gas recirculation system has an EGR valve disposed in an EGR duct connecting an engine intake and exhaust. A diaphragm of said EGR valve is actuated via vacuum from the engine intake, the application of the vacuum is controlled via an electronic valve regulator (EVR). The EVR is provided a fixed signal to cause it to be fully open when it is determined that the engine is about to encounter a condition in which there is insufficient vacuum to open the EGR valve. The EVR is provided a variable signal during other operating conditions in which there is sufficient vacuum to open the EGR valve.
