FIELD: engines and pumps.
SUBSTANCE: engine running operation mode, that has a purging system (18) of a fuel vapour, is contained in that one directs the draw-in air through the first throttle (44) and diffuser (47) that is placed in the bypass conduit (502). The bypass conduit (502) is attached in parallel nearby the second throttle (67) that is placed in an afflux. One releases vaporized fuel flow from the purging system (18) of a fuel vapour to the diffuser (47) afflux in response to the operating conditions. One regulates the vaporized fuel flow range that is released to the diffuser (47) afflux by virtue of the fuel vapour purging valve (98) that is attached to the purging system (18) of a fuel vapour on the basis of the airflow rate through the diffuser (47), and also of the temperature and air pressure. The version of the engine running operation mode and engine system are discovered.
EFFECT: flow restriction in the engine intake system obviation.
