PISTON-TYPE INTERNAL COMBUSTION ENGINE WITH THROTTLE-FREE LOAD CONTROL AND COMPRISING A DEVICE FOR GENERATING A NEGATIVE PRESSURE, AND METHOD FOR USING SAID DEVICE

摘要

The present invention relates to a piston-type internal combustion engine comprising gas-exchange valves which can be driven in a completely variable manner by a motor control (2) and which communicate with an air supply channel (4) provided with a device (6) for generating a negative pressure using the energy components of the air flowing through said air supply channel (4). This device is provided with means that can be driven for adaptation to the modifications in the flow energy which are inherent to the operation, and communicates with at least one negative-pressure user (8, 9, 10) through at least one negative-pressure duct (7).
