Abstract
Provided is a hybrid vehicle that includes a power train including an internal combustion engine equipped with a plurality of cylinders and a drive motor unit. The drive motor unit includes an electric motor coupled to the internal combustion engine without a clutch. The internal combustion engine includes one or more decompression devices that are each installed for a subset of one or more cylinders and that operate to release compression pressure in the subset of one or more cylinders in at least one of the course of an engine stop and course of an engine start-up in which combustion is not performed. The subset of one or more cylinders are selected such that, when the one or more decompression devices are operating, compression is not produced sequentially in cylinders that are adjacent to each other in terms of the firing order.
Claims3
A hybrid vehicle, comprising a power train including an internal combustion engine equipped with a plurality of cylinders and a drive motor unit,
- wherein the drive motor unit includes an electric motor coupled to the internal combustion engine without a clutch interposed between the drive motor unit and the internal combustion engine,
- wherein the internal combustion engine includes one or more decompression devices that are each installed for a subset of one or more cylinders that are one or more but not all of the plurality of cylinders, the one or more decompression devices operating to release compression pressure in the subset of one or more cylinders in at least one of a course of an engine stop and course of an engine start-up in which combustion is not performed, and
- wherein the subset of one or more cylinders are selected such that, when the one or more decompression devices are operating, compression is not produced sequentially in cylinders that are adjacent to each other in terms of a firing order of the internal combustion engine.
