摘要： An engine includes a single cylinder, at least one sensor, a fuel injector, and a controller. The at least one sensor is configured to generate sensor data for an engine condition. The controller is configured to perform a comparison of the engine condition to a threshold and in response to the comparison, generate a first command to deactivate the fuel injector after a first predetermined time period and a second command to reactivate the fuel injector after a second predetermined time period.

摘要： The present invention describes a fuel-management system for minimizing particulate emissions in turbocharged direct injection gasoline engines. The system optimizes the use of port fuel injection (PFI) in combination with direct injection (DI), particularly in cold start and other transient conditions. In the present invention, the use of these control systems together with other control systems for increasing the effectiveness of port fuel injector use and for reducing particulate emissions from turbocharged direct injection engines is described. Particular attention is given to reducing particulate emissions that occur during cold start and transient conditions since a substantial fraction of the particulate emissions during a drive cycle occur at these times. Further optimization of the fuel management system for these conditions is important for reducing drive cycle emissions.

摘要： A controller for an aftertreatment system coupled to an engine is configured to: in response to receiving an engine shutdown signal, determine an estimated amount of ammonia stored on a selective catalytic reduction (SCR) catalyst included in the aftertreatment system; in response to determining that the estimated amount of ammonia stored in the SCR catalyst is less than an ammonia storage threshold, cause flow of a heated gas towards the SCR catalyst; cause insertion of reductant into an exhaust gas flowing through the aftertreatment system; and in response to determining that the estimated amount of ammonia stored in the SCR catalyst is equal to or greater than the ammonia storage threshold, cause shutdown of the engine.

摘要： Systems and methods for operating an internal combustion engine that is coupled to a power split transmission are described. In one example, the internal combustion engine is operated in a speed control mode or a torque control mode in response to a braking torque and a transmission shift command. Operating the engine in the torque control mode may allow the engine to charge a battery while a neutral transmission state is selected.

摘要： In an internal combustion engine having a cylinder in which an air-fuel mixture of gaseous fuel and intake air is combusted, an intake passage connected to the cylinder, and a supercharger for supercharging the intake air, in a case where backfire is generated in a set period before supercharging is performed by the supercharger, supercharging is performed at a smaller supercharging pressure than in a case where backfire is not generated in the set period.

摘要： A method for starting an internal combustion engine and a motor vehicle are provided. The internal combustion engine includes a plurality of cylinders. To start the internal combustion engine while deactivated, a predefined amount of working gas is introduced into the cylinder that fires first. A crankshaft of the internal combustion engine is driven by an electric motor and by the movement of a piston coupled to the crankshaft and associated with the cylinder that fires first to introduce the predefined amount of working gas. Subsequently, the internal combustion engine is started by the ignition of a mixture including the predefined amount of working gas and a predefined amount of fuel inside the cylinder that fires first.

摘要： A vehicle control system includes an accelerator sensor which detects an accelerator opening, and a processor which sets a target acceleration of a vehicle based on the detected accelerator opening, sets a target torque of a drive source based on the set target acceleration, and controls the drive source to generate the set target torque. In a case where the target acceleration at a time when the accelerator opening is increased is set as a depression-increasing target acceleration and the target acceleration at a time when the accelerator opening is decreased is set as a pedal-returning target acceleration, under the same condition of the accelerator opening, the processor sets the target acceleration such that the depression-increasing target acceleration and the pedal-returning target acceleration are different from each other in a predetermined range of an upper limit acceleration or less and a lower limit acceleration or greater.
