摘要： A system and method for transient torque control of a direct injection spark ignition engine include controlling airflow and fuel flow rather than ignition timing so that spark timing may be set for best fuel economy. The system and method are particularly suited for variable cam timing or variable valve timing DISI engines where valve timing enables a sufficiently fast engine torque response to achieve transient control. The present invention may be used for torque-based speed control strategies, such as idle speed control or cruise control. The invention includes determining a maximum available airflow to determine whether a desired torque and air/fuel ratio can be achieved using airflow. Otherwise, the invention uses fuel flow control based on the maximum available air flow to provide the desired engine output torque and air/fuel ratio.

摘要： A system and method for engine/speed control of a direct injection spark ignition engine include operating the engine in a stratified charge mode and controlling speed based on engine set points for best performance using fuel as a primary torque actuator and airflow as a secondary torque actuator whenever possible to maintain spark at or near MBT. When current operating conditions and/or system constraints prevent use of engine set points corresponding to best performance, speed control becomes the primary objective. Systems and methods according to the present invention improve the compromise between speed control and best performance set-point objectives.

摘要： An electronic engine controller (EEC) controls transient engine operation by generating a desired torque value which is indicative of an engine torque desired by a driver of the vehicle and by generating a desired air/fuel ratio value which is indicative of a desired air/fuel ratio to be combusted by the engine. The EEC also generates an actual torque value which is indicative of the actual engine torque and an actual air/fuel value which is indicative of the air/fuel ratio actually combusted by the engine. The actual A/F may be the output of a standard, switching type EGO sensor. An air/fuel difference value indicative of the difference between the actual air/fuel value and the desired air/fuel value is generated, and a torque difference value, indicative of the difference between the actual torque value and the desired torque value is generated. The air flow rate and the fuel flow rate into cylinders of the engine is calculated respectively as a function of the torque difference value and the air/fuel difference value. The engine may take one of many forms, including an engine where air flow and fuel flow rates may be controlled individually on a cylinder to cylinder basis.

摘要： A method for controlling a spark ignited direct injection internal combustion engine having an air intake with a throttle valve positioned therein and a plurality of cylinders operable in at least a homogeneous operating mode with a homogeneous air/fuel mixture and an associated range of allowable homogeneous air/fuel ratios and a stratified mode with a stratified air/fuel mixture and an associated range of allowable stratified air/fuel ratios, wherein the homogeneous range and stratified range do not overlap, includes determining a desired value for an engine operating parameter based on current engine operating conditions wherein the desired value results in scheduling of an air/fuel ratio between the homogeneous range and stratified range of allowable air/fuel ratios, operating a first portion of the cylinders in the homogenous operating mode, and operating a second portion of the cylinders in the stratified operating mode such that a combined air/fuel ratio associated with the first and second portions of the cylinders approaches the scheduled air/fuel ratio. The invention provides an additional degree of freedom in controlling a DISI engine without additional sensor/actuator cost and provides a hybrid operating mode which closes the gap between stratified and homogeneous operating modes.

摘要： A speed control system is shown for an internal combustion engine (10) having an intake manifold (44) and throttling device (96) connected thereto in parallel with the main throttle plate (62). After an idle speed command is detected (200), the engine (10) is decelerated (204-230) to a preselected speed by adjusting the throttling device (96) to concurrently force both engine speed and engine acceleration within a predetermined acceleration/speed range(s). When the preselected speed is reached, engine speed is regulated (300-328) to a desired idle speed by adjusting the throttling device (96) to force a difference between the engine and idle speed towards zero.

摘要： A fuel injection method and strategy for an internal combustion engine wherein the fuel injection event that occurs during each combustion cycle of a four-cycle internal combustion engine. A first fuel injection event may occur during the intake stroke of the combustion cycle, thereby creating a lean homogeneous air/fuel mixture. A second fuel injection event may occur during the compression stroke. The combustion gases created in the combustion chamber of the engine are transferred to an exhaust system during the exhaust stroke. The injected fuel mixes with the air present in the combustion chamber to create a lean air/fuel mixture. The valve timing for the engine is deliberately adjusted to a setting that is less than the maximum torque setting where hydrocarbon production occurs during the combustion event. The exhaust gas hydrocarbon content for any given ignition spark timing increases as the injection timing before top dead center is increased.
