Title:
HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2019157641
Kind Code:
A
Abstract:
To provide a hybrid vehicle which can suppress resonance by using a decompression device in a first power transmission resonance area while reducing a cost by reducing the number of installation cylinders of the decompression device.SOLUTION: A hybrid vehicle comprises a power transmission 10 including an internal combustion engine 20 having a plurality of cylinders, and a drive motor unit 60. The drive motor unit 60 includes a first motor generator 62 connected to the internal combustion engine 20 not via a clutch. The internal combustion engine 20 includes a decompression device 26 which is installed at a part of the cylinders (#2, #3), and operates so as to release the compression pressure of a part of the cylinders at least at either of an engine stop process at which combustion is not performed, and an engine start process. When the decompression device 26 is in an operation state, the decompression device 26 is installed in a part of the cylinders (#2, #3) which are selected so that compression is not continuously generated in the cylinders in which explosion orders adjoin each other.SELECTED DRAWING: Figure 4
