摘要： Disclosed is a fuel/air mixture supply system for an internal combustion engine of the single-point fuel injection type wherein, the intake manifold system is formed with a first fuel/air supply passage which inspires atmospheric air and which has fitted generally at a midpoint thereof a fuel injection valve which injects fuel into the inspired air. The fuel/air mixture then proceeds to a first set of branched passages, each one of which conducts the fuel/air mixture to a cylinder of the engine. Further, there is provided a second air supply passage which inspires atmospheric air and which branches into a second set of branched passages, each one of which conducts air to a cylinder of the engine. The first fuel/air supply passage is smaller than the second air supply passage, and the first set of branched passages are smaller than the second set of branched passages. The flow of air/fuel mixture in the first fuel/air supply passage is controlled by a first throttle valve, and the flow of air in the second air supply passage and/or the second branched passages is controlled by a regulating means responsive to the operation of the first throttle valve, so as to be substantially zero when the first throttle valve is open an amount less than a certain predetermined amount, while, when the first throttle valve is opened greater than the certain predetermined amount, the flow is progressively increased.

摘要： An intake system of an internal combustion engine having a carburetor with a primary venturi and a secondary venturi concentrically disposed within the primary venturi by a bridge member which extends into contact with an inner wall of a throat portion of the primary venturi. A fuel delivery conduit is disposed within the bridge member and spans the secondary venturi with its leading end sealingly received in the side of the secondary venturi opposite the bridge member. The fuel delivery conduit is inclined with respect to the axis of the secondary venturi so that the leading end portion of the conduit extends in an upstream direction. The fuel delivery conduit also has an opening through which fuel is dischargable. A single needle member is fixedly attached to the bottom of the secondary venturi and projects in a downstream direction with respect to the flow of the air passing through the secondary venturi. The needle member is in substantial axial alignment with the portion of the secondary venturi from which the spanning fuel delivery conduit projects into the secondary venturi.

摘要： A carburetor is disclosed of the variable venturi type, which has a bypass passage bypassing the throttle valve, which is controlled during starting and warming up of the engine by a piston which adjusts its flow resistance, and which is urged against the biasing action of a spring by the vacuum suction downstream of the throttle valve. The maximum open position of this piston is controlled by a heat-sensitive element which advances this position in the direction of closing the bypass passage as the engine warms up, until it is completely closed when the engine is warm. Air is fed into a supplier which supplies fuel to the carburetor inlet passage to mix with the fuel supplied thereby in an amount which varies from a minimum when the vacuum downstream of the throttle valve is minimum to a maximum when the vacuum downstream of the throttle valve is maximum. Further, the amount of fuel supplied by the fuel supplier is adjusted to be greater when the engine temperature is lower than when it is higher. Thereby choking action is provided for a cold engine, and also a function of providing an enriched mixture upon acceleration during warming up is provided.

摘要： Air drawn into a carburetor main fuel passage for adjustment of the air-fuel ratio of an engine air-fuel mixture is either stepwise or continuously prevented from being undesirably increased with increases in the engine load by either closing an additional passage for the air at an engine load above a predetermined value or continuously reducing the effective cross sectional area of a variable orifice in a passage or an additional passage for the air with increases in the engine load.
