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: 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: Methods and systems are provided for adjusting engine compression ratio (CR) and spark timing to attain particulate filter (PF) regeneration temperature. In one example, a method may include, in response to PF load reaching a threshold and PF temperature being lower than the PF regeneration temperature, lowering the CR and then selectively adjusting spark timing based on an estimated residual gas fraction (RGF) at the lower CR.

Abstract: A method for functional monitoring of an apparatus for variable setting of a cylinder compression in a reciprocating-piston internal combustion engine is described, including ascertaining a value of an engine parameter which is indicative of an engine position of the internal combustion engine at a defined cylinder compression; comparing the ascertained value with a further value of the engine parameter; and determining, depending on a result of the comparison, whether the apparatus for variable setting of the cylinder compression is functioning correctly.

Abstract: In a vehicle with an automatic transmission, an internal combustion engine is provided with a variable compression ratio mechanism. A target compression ratio of the variable compression ratio mechanism is determined based on a demand load and an engine rotation speed with reference to a compression ratio map. A reverse-drive compression ratio map is selected when the automatic transmission is in a reverse drive position; a first compression ratio map is selected when an actual speed reduction ratio of the transmission is low; and a second compression ratio map is selected when the actual speed reduction ratio of the transmission is high. A variable control range of the compression ratio is narrower in the second compression ratio map than in the first compression ratio map and is narrower in the reverse-drive compression ratio map than in the first and second compression ratio maps.

Abstract: It comprises one or more cylinders with pistons therein and mutually opposed power cams connected to respective first and second rotary shafts. The reciprocating pistons act on the power cams to impart a rotating motion to the rotary shafts. An attachment device is provided for connecting the rotary shafts to each other. The attachment device includes a shifting device for changing the relative angular position of the first and second rotary shafts. The result is engine distribution and compression ratio are changed dynamically.
