Abstract: An internal combustion engine control device includes: a temperature acquisition unit configured to acquire the temperature of an internal combustion engine at the time when it is requested to start the internal combustion engine; a motoring execution unit configured to execute motoring of the internal combustion engine using the motor when it is requested to start the internal combustion engine; and an in-cylinder pressure control unit configured to control the in-cylinder pressure of the internal combustion engine during the motoring based on the temperature of the internal combustion engine. The in-cylinder pressure control unit is configured to execute in-cylinder pressure increase control, in which the in-cylinder pressure is increased when the temperature of the internal combustion engine is equal to or less than a predetermined threshold temperature compared to when the temperature of the internal combustion engine is higher than the threshold temperature, since the motoring is started.

Abstract: An adaptive, any-fuel reciprocating engine using sensor feedback integration of high-speed optical sensors with real-time control loops to adaptively manage the electronic actuation schemes over a range of engine loads and fuels. The engine uses one or more optical sensors to collect specific types of gas property data via a spectroscopic technique to adaptively control various components within the engine.

Abstract: Spark ignition engine operation at higher RPM so as to reduce alcohol requirements in high efficiency alcohol enhanced gasoline engines is disclosed. Control of engine upspeeding (use of a higher ratio of engine RPM to wheel RPM) so as to achieve an alcohol reduction objective while limiting any decrease in efficiency is described. High RPM alcohol enhanced gasoline engine operation in plug-in series hybrid powertrains for heavy duty trucks and other vehicles is also described.

Abstract: A hybrid vehicle includes an internal combustion engine and a motor generator, wherein the internal combustion engine includes a variable compression ratio mechanism structured to vary in mechanical compression ratio depending on variation in position of a compression ratio control member structured to move due to driving of an electric actuator. A control method for the hybrid vehicle includes: measuring a state of charge of a battery connected to the motor generator; and in response to regenerative operation of the motor generator in a state that the state of charge of the battery is equal to or higher than a predetermined level, consuming generated electric power by driving the electric actuator of the variable compression ratio mechanism.

Abstract: A piston for an internal combustion engine comprises a skirt defining an inner space of the piston and having a skirt bottom; and a target arranged under the skirt bottom to engage with a passage detector arranged in the engine. The target is supported by a holding body held at least partially inside the inner space of the piston. The present disclosure likewise relates to an engine comprising such a piston.

Abstract: Methods and systems are provided for controlling LP-EGR flow in a variable displacement engine. In one example, a method may include providing a higher fixed LP-EGR percentage relative to a total intake air flow during a VDE mode, and providing a lower fixed EGR percentage relative to the total intake air flow during a non-VDE mode. Further, during a tip-out when operating in the VDE mode at a load below a threshold, transitioning out of the VDE mode after transitioning the LP-EGR from the higher fixed percentage to the lower fixed percentage.

Abstract: Methods and systems are provided for improving calibration of a variable compression ratio engine. Cylinder-to-cylinder compression ratio variations are detected and accounted for by comparing cylinder fuel flow and IMEP at each compression ratio setting. Dilution parameters including EGR and VCT schedule are also calibrated to account for the cylinder-to-cylinder compression ratio variations.

Abstract: A variable compression ratio internal combustion engine is provided with a variable compression ratio mechanism in which a mechanical compression ratio of the internal combustion engine changes in accordance with a rotational position of a control shaft, a low compression ratio side stopper, a high compression ratio side stopper, a sensor for detecting a rotational position of a drive shaft of an actuator, and an arm press-fitted onto the drive shaft. Relative rotation between the arm and the drive shaft occurs when a torque exceeding an upper-limit torque has been applied. The drive shaft or the control shaft is caused to move to restriction positions restricted by the respective stoppers, and then a diagnosis on the presence or absence of the relative rotation is executed, based on the detected values at the respective restriction positions.
