摘要： An air induction system for an engine is disclosed. The air induction system has a compressor operable to compress air directed into the engine, a bypass valve, and a throttle valve. The bypass valve may be disposed between the compressor and the engine and may have a valve element movable to selectively divert a portion of the compressed air away from the engine in response to a desired air-to-fuel ratio of the engine. The throttle valve may be disposed between the bypass valve and the engine and may have a valve element movable to selectively restrict the flow of compressed air into the engine in response to a desired air-to-fuel ratio of the engine. The movements of the valve elements of the bypass and throttle valves may be substantially sequential.

摘要： An internal combustion engine has at least one combustion chamber and a piston configured to reciprocate within the at least one combustion chamber between a top-dead-center position and a bottom-dead-center position. The internal combustion engine also has a pre-combustion chamber, an air induction system, a fuel system, a spark plug at least partially disposed within the pre-combustion chamber. The air induction system is configured to direct air into the at least one combustion chamber. The fuel system is configured to direct gasoline into the at least one combustion chamber. The spark plug is configured to selectively ignite a mixture of the air and gasoline. The internal combustion engine also has an exhaust system configured to direct exhaust from the at least one combustion chamber and an exhaust gas recirculation system configured to selectively redirect at least a portion of the exhaust from the exhaust system back to the air induction system.

摘要： A control system for an engine having a cylinder is disclosed having an engine valve movable to regulate a fluid flow of the cylinder and an actuator associated with the engine valve. The control system also has a controller in communication with the actuator. The controller is configured to receive a signal indicative of engine speed and compare the engine speed signal with a desired engine speed. The controller is also configured to selectively regulate the actuator to adjust a timing of the engine valve to control an amount of air/fuel mixture delivered to the cylinder based on the comparison.

摘要： A control system for an engine having a first cylinder and a second cylinder is disclosed including an air/fuel ratio control device configured to affect an air/fuel ratio within the first and second cylinders. The control system also has a first sensor configured to generate a first signal indicative of a combustion pressure within the first cylinder and a second sensor configured to generate a second signal indicative of a combustion pressure within the second cylinder. The control system further has a controller in communication with the air/fuel ratio control device and the first and second sensors. The controller is configured to determine a NOx production within the first cylinder based on the first signal and determine a NOx production within the second cylinder based on the second signal. The control is also configured to calculate a total NOx production of the engine based on at least the NOx produced within the first and second cylinders and selectively regulate the air/fuel ratio control device to adjust the air/fuel ratio within the first and second cylinders based on the total NOx production of the engine.
