摘要： An internal combustion engine can form, in a combustion chamber, a fuel-air mixture region located on the first intake port side and containing mainly a fuel-air mixture, and a burned gas region located on the second intake port side and containing burned gas. When the region and a burned gas region are formed, the internal combustion engine determined injection rates of a first fuel injection valve and a second fuel injection valve so that fuel is injected from the first fuel injection valve and second fuel injection valve respectively, depending on an EGR rate. The injection rates are determined such that the injection rate of the first fuel injection valve is increased in accordance with the rise of the EGR rate.

摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

摘要： An internal combustion engine includes two-step variable lift control mechanisms configured to control magnitude of valve lift of intake and exhaust valves to one of two discrete steps including low-lift valve open positions and high-lift valve open positions. A method for operating the engine includes commanding a transition from a first combustion mode to a second combustion mode. Upon commanding the transition, closing of a plurality of secondary throttle valves configured to control intake airflow to a plurality of intake runners upstream of a plurality of intake valves is initiated. Positions of the plurality of secondary throttle valves are then adjusted to achieve a preferred air charge. The two-step variable lift control mechanisms are then commanded to switch from a first of the two discrete steps to a second of the two discrete steps.

摘要： An engine controller capable of reducing torque fluctuation and the like in change between spark ignition combustion and homogeneous charge compression ignition combustion is provided. Spark ignition burning mode or homogeneous charge compression ignition burning mode is selectively set as burning mode according to the operating state of an engine. In spark ignition burning mode, a spark plug is used. In homogeneous charge compression ignition burning mode, fuel is burned utilizing pressure rise in a combustion chamber in conjunction with the ascent of a piston. The burning mode is changed between these modes. In transition for change between the spark ignition burning mode and the homogeneous charge compression ignition burning mode, the following measure is taken: a period during which the lift amount and/or the valve opening period (IVevent) of an intake valve is made smaller than a set value for the homogeneous charge compression ignition burning mode is provided.

摘要： A system for controlling intake airflow of an engine includes a mode determination module, a throttle valve control module, and a valve actuation module. The mode determination module generates a mode signal based on an engine speed signal and an engine load signal. The mode signal indicates one of a spark ignition mode and a homogeneous charge compression ignition mode. The throttle valve control module generates a valve control signal based on the mode signal, a temperature signal, and a plurality of valve position signals that indicate positions of first and second throttle valves. The throttle valve control module controls the positions of the first and second throttle valves to regulate flow rates of intake air into an intake manifold of the engine via a heat exchanger based on the valve control signal. The valve actuation module actuates the first and second throttle valves based on the valve control signal.
