초록 ▼

A multi-mode internal combustion engine is described. As one example, the engine may be transitioned between a two stroke mode and a four stroke mode in coordination with a transmission shift by adjusting a number of strokes performed by the engine per combustion cycle while shifting the transmissio

대표청구항 ▼

1. A vehicle propulsion system, comprising: an internal combustion engine;a plurality of drive wheels;a transmission operatively coupling the engine to said plurality of drive wheels; anda control system configured to: operate the engine in a two stroke mode during a first operating condition;operate the engine in a four stroke mode during a second operating condition; andadjust a gear ratio of the transmission responsive to whether the engine is operated in the two stroke mode or the four stroke mode, where the control system is further configured to transition the engine between the two stroke mode and the four stroke mode while the gear ratio of the transmission is being adjusted. 2. The vehicle propulsion system of claim 1, where the control system is further configured to adjust the gear ratio of the transmission differently depending on whether the engine is operated in the two stroke mode or the four stroke mode before the transition. 3. The vehicle propulsion system of claim 1, where the control system is further configured to increase the gear ratio of the transmission when the engine is operated in the two stroke mode. 4. The vehicle propulsion system of claim 1, where the control system is further configured to reduce the gear ratio of the transmission when the engine is operated in the four stroke mode. 5. The vehicle propulsion system of claim 1, where the transmission is a continuously variable transmission. 6. The vehicle propulsion system of claim 1, where the transmission includes a plurality of discrete gear ratios. 7. The vehicle propulsion system of claim 1, where the first operating condition includes a lower engine rotational speed and the second operating condition includes a higher engine rotational speed. 8. The vehicle propulsion system of claim 1, where the first operating condition includes a first accelerator pedal position and the second operating condition includes a second accelerator pedal position.
