Verfahren und Vorrichtung zur Steuerung der Einlassluft einer fremdgezündeten Viertaktbrennkraftmaschine

摘要

A main air inlet conduit (2) controlled by a choke valve (9) opens into or close to the combustion chamber (1). A secondary bypass conduit (10) controlled by a blocking valve (11) leaves the main conduit just upstream of the choke valve to deliver air to one (4) of a pair of branches of the inlet conduit. The bypass conduit is of the same cross-sectional area as the main conduit, with its blocking valve controlled in response to engine conditions. An additional conduit (7) controlled by a valve (8) may deliver recycled exhaust gases to the other branch (3) of the inlet conduit. A one-way valve (12) is located in the first branch upstream of the opening of the bypass conduit.
