摘要: An engine system and method for operating an engine including a central throttle and a port throttle is disclosed. In one example, the central throttle and port throttle are adjusted to improve air flow distribution to engine cylinders. The system and method may be particularly beneficial for turbocharged engines.

摘要: A method for operating an engine with a fuel reformer is presented. In one embodiment a method for operating an engine by injecting a gaseous fuel and a liquid fuel to at least an engine cylinder is presented. The method may prioritize the injection of the gaseous fuel in response to an amount of gaseous fuel stored in a fuel storage tank.

摘要: Various systems and method for heating an engine in a vehicle are described. In one example, intake air flowing in a first direction may be heated via a gas-to-gas heat exchange with exhaust gases. The heated intake air may then be used in a subsequent gas-to-liquid heat exchange to heat a fluid circulating through the engine. In another example, intake air flowing in a second direction may be heated via a heat exchange with exhaust gases in order to cool an exhaust catalyst.

摘要: Methods and systems are provided for improving fuel usage while addressing knock by adjusting the use of spark retard and direct injection of a fluid based on engine operating conditions and the composition of the injected fluid. One or more engine parameters, such as EGR, VCT, boost, throttle position, are coordinated with the direct injection to reduce torque and EGR transients.

摘要: Methods are provided for operating an engine with a variable fuel blend in a cylinder, where the variable fuel blend varies a peak achievable engine torque for a given operating condition. One example method comprises selectively operating an engine actuator that affects engine torque and engine fuel economy at the given operating condition, and extending operation of the actuator to higher engine torques as a peak engine torque for the given operating condition increases.
