摘要： Engine controllers and control schemes are provided for managing engine state transitions requiring increased compressor pressure ratios in turbocharged engines operating in a cylinder output level modulation mode (e.g., skip fire, multi-level skip fire, or firing level modulation modes). In some circumstances, turbo lag can be mitigated by initially transitioning the engine to an intermediate effective firing density that is higher than both the initial and target effective firing density to increase the flow of gases through the engine and the turbocharger while maintaining a compressor ratio the same as or close to the initial compressor pressure ratio. After reaching a point where the desired torque is actually generated at the intermediate effective firing density, the operational effective firing density is gradually reduced to the target effective firing density while increasing the operational compressor pressure ratio to the target compressor ratio.

摘要： A control device for controlling an engine provided with a fuel pump including a pressurizing chamber, a plunger inserted into the pressurizing chamber and which changes a volume of the pressurizing chamber, and an on-off valve configured to open and close a suction port, is provided. When a pressurizing cycle consists of a period of pressurizing stroke in which the volume of the pressurizing chamber is reduced to allow fuel to be pressurized and a period of suction stroke in which the volume of the pressurizing chamber is increased to allow fuel to be drawn into the pressurizing chamber, a closing cycle of the on-off valve is controlled so that a ratio of the closing cycle to the pressurizing cycle becomes smaller in a second combustion mode where a partial compression-ignition combustion is performed than in a first combustion mode where SI combustion is performed.

摘要： Using machine learning for cylinder misfire detection in a dynamic firing level modulation controlled internal combustion engine is described. In a classification embodiment, cylinder misfires are differentiated from intentional skips based on a measured exhaust manifold pressure. In a regressive model embodiment, the measured exhaust manifold pressure is compared to a predicted exhaust manifold pressure generated by neural network in response to one or more inputs indicative of the operation of the vehicle. Based on the comparison, a prediction is made if a misfire has occurred or not. In yet other alternative embodiment, angular crank acceleration is used as well for misfire detection.

摘要： An engine controller according to one aspect of the invention is applied to a cylinder injection engine including a fuel injection valve that directly injects fuel into a cylinder. The engine controller determines whether knocking is occurring based on a signal from a knocking sensor. When the knocking is occurring, the engine controller performs partial lift fuel injection at a predetermined timing close to an ignition timing. The partial lift fuel injection is performed with a lift amount of a valve body of the fuel injection valve limited within a range between a minimum lift amount (0) and a partial lift amount, which is smaller than a maximum lift amount.

摘要： A split-cycle engine includes: a first cylinder housing a first piston, wherein the first piston performs an intake stroke and a compression stroke, but does not perform an exhaust stroke; a second cylinder housing a second piston, wherein the second piston performs an expansion stroke and an exhaust stroke, but does not perform an intake stroke; and a valve chamber housing a valve, the valve comprising an internal chamber that selectively fluidly couples to the first and second cylinders, wherein the valve and internal chamber move within the valve chamber and relative to the first and second cylinders.

摘要： A method for operating an internal combustion engine having a plurality of cylinders includes: measuring, by exhaust gas sensors arranged at an exhaust gas of every cylinder for which cylinder-specific combustion control is carried out, for each respective cylinder, at least one actual combustion value; comparing each respective measured actual combustion value with a reference combustion value to determine at least one cylinder-specific control deviation for every cylinder for which cylinder-specific combustion control is carried out; determining at least one cylinder-specific control variable for every cylinder for which cylinder-specific combustion control is carried out based on the cylinder-specific control deviation or on every cylinder-specific control deviation; and operating each cylinder for which cylinder-specific combustion control is carried out based on the respective cylinder-specific control variable to bring the respective actual combustion value closer to the respective reference combustion value and minimize the respective control deviation.

摘要： Methods and systems for simultaneously operating port fuel injectors and direct fuel injectors of an internal combustion engine are described. In one example, a port fuel injection window is shorted to provide time for scheduling a direct fuel injector pulse width so that the direct fuel injector pulse width may be adjusted so that a desired amount of fuel enters a cylinder.

摘要： In a spark-ignition internal combustion engine including a port injection valve that injects fuel into an intake port and an in-cylinder injection valve that injects fuel directly into a combustion chamber, switching from a first combustion mode which realizes lean combustion with an air-fuel ratio that is leaner in fuel than a theoretical air-fuel ratio and which is constituted mainly by fuel injection by the port injection valve, to a second combustion mode which realizes lean combustion by fuel injection in an intake stroke by the in-cylinder injection valve is enabled while maintaining a low amount of NOx emissions. The control device for an internal combustion engine of this disclosure makes a discharge time period of a spark plug in the second combustion mode longer than a discharge time period in the first combustion mode.
