| 摘要 |
The invention relates to an oil spray lubrication and cooling device for a variable compression ratio engine, including at least one injector (701, 712, 713) which is placed in the engine block (100) of the variable compression ratio engine such as to spray oil onto at least one of the moving components of the engine. The aforementioned moving components include at least one piston (2), the lower part of which is solidly connected to a transmission element (3) that co-operates with a rolling guide device (4) and a toothed wheel (5) which co-operates with (i) a connecting rod (6) which is connected to a crankshaft (9) and (ii) a control rack (7) opposite the transmission element (3). The vertical position of the control rack in relation to the engine block (100) is controlled by a control device (12).
