| 摘要 |
The invention relates to a device for vaporising and expanding a liquefied petroleum gas for the dual-fuel thermal internal-combustion engine of an automobile selectively run by sequential injection of gasoline or liquefied petroleum gas (LPG), using a vaporiser-expander (5) that comprises two separate loops (7, 8), i.e. one (7) for the LPG and the other (8) for a coolant, characterised in that both loops (7, 8) are designed so as to be symmetrical and to be integrated into each other on either side of a common wall of a single groove, made from one of the faces of a separation partition (13) of the body (14) of the vaporiser-expander (5), thus defining a coil or meanders. |
