摘要:
A throttle mechanism (10) for an engine of a motor vehicle comprising a throttle body (12) having an inner wall (36) defining a bore (38) extending therethrough and an outer wall (40), the bore having a longitudinal axis (X); a shaft (14) extending across the bore and having a longitudinal axis (y) substantially perpendicular to the longitudinal axis of the bore, the shaft being rotatably mounted in the inner wall of the throttle body for pivotal movement about the longitudinal axis of the shaft, at least one end (42) of the shaft passing through the inner wall to extend beyond the outer wall; a flap valve (16) secured to the shaft inside the bore for movement between a fully open position and a substantially closed position on rotation of the shaft; means (18,20) secured to the said one end of the shaft adjacent the outer wall for rotating the shaft; and an air horn (24) securable to the throttle body for the passage of air into the throttle body; the throttle body having a pair of end faces (35,37) which are substantially identical, and two apertures (46,48) passing therethrough from one end face to the other through which securing means (58) can extend to secure the throttle body to the engine, the apertures having a longitudinal axis which is substantially parallel to the longitudinal axis of the bore, and the apertures being diametrically opposed relative to the longitudinal axis of the bore.
摘要:
The present invention pertains to the field of engine construction and may be used in the inlet systems of internal combustion engines for processing a portion of the rich air-fuel mixture fed into the main flow, wherein the liquid fuel is pulverised and converted into gas. The purpose of this invention is to increase fuel savings, to reduce the exhaust gas toxicity and to enable the use of a cheaper low-octane fuel. The method for preparing the air-fuel mixture comprises using the heat from the hot gases produced for heating the excessively rich mixture flow that contains between 10 and 100 % of petrol to be used by the engine, wherein said heating is carried out before mixing the mixture with the second flow. The mixture is then submitted in one or more steps to the thermal action of activators with compensation for the air used during the reactions. The device of the present invention comprises a heat exchanger (1) as well as a unit for dosing the mixture components (2), wherein said unit is connected by an inlet duct (5) to the mixture circuit through which said mixture is fed into a chamber (3) with an activator (4). The hot gases are generated in this chamber and flow through the inlet duct (6) of the gas circuit as well as through the outlet duct (7) thereof into the engine inlet system. The activator (4) chamber is connected to a pipe (8) and to a plurality of nozzles (9) for supplying additional air to the activator. The heat exchanger includes a body having an embossed partition therein that defines a plurality of cells-channels for the flow of the heat-carrier and the heating medium, wherein the walls of each cell-channel are connected together at their end portion up to half the height of the channel.

摘要:
Die Erfindung betrifft eine quantitätsgesteuerte Brennkraftmaschine (2) mit zumindest einem im Ansaugtrakt (1) vorgesehenen Drosselorgan (5) sowie mit einem System (7) zur Einleitung von Zusatzluft in die Ansaugkanäle (6b) der einzelnen Brennkraftmaschinen-Zylinder, wobei ein Steuerorgan (8) zur Beeinflussung der Zusatzluftmenge vorgesehen ist. Die Betätigung des Steuerorganes (8) erfolgt zusammen mit der Betätigung des Drosselorganes (5), wobei ausgehend von einer Schließposition sowohl des Steuerorganes (8) als auch des Drosselorganes (5) bei einer Lasterhöhung zunächst nur das Steuerorgan (8) öffnet und hierdurch das System (7) zur Einleitung von Zusatzluft mit Ansaugluft versorgt, während das Drosselorgan (5) den Ansaugtrakt (1) zur Versorgung der Ansaugkanäle (6b) mit Ansaugluft erst bei einer weiteren Lasterhöhung freigibt. Hierdurch kann das sog. Zusatzluftsystem (7) in seinem wichtigsten Betriebsbereich, nämlich dem Niederlastbereich der Brennkraftmaschine, die größtmögliche Wirkung entfalten. Angegeben sind verschiedene Ausführungsformen des Steuerorganes (8), bspw. als erste Stufe eines Register-Drosselklappenstutzens (10), dessen zweite Stufe das Drosselorgan (5) bildet.
