Abstract: To save fuel during engine deceleration, it has been proposed that the supply of fuel should be cut off. Such proposals have involved substantial redesign of the carburettor. The carburettor described comprises a throttle valve (14), an idling port (26) through which a fuel/air mixture is supplied on the down-stream side of the valve (14) when the latter is in a closed position, a channel (16) leading to the idling port and along which the fuel/air mixture is drawn, a longitudinally adjustable idle mixture adjusting device (27) having a tapered tip (38) projecting into the channel (16) and manually movable to move the tip (38) towards and away from the port (26) to set the idling mixture of the engine, and means operable through the idle mixture ajdusting device (27) for preventing the supply of fuel through the idling port during engine deceleration. The supply of fuel can be prevented by blocking the idling port (26) and/or by venting the region adjacent that port (26). Such a device (27) is simple to install and does not require significant redesign of a carburettor.

Abstract: A system (10) for controlling fuel supply to an internal combustion engine via a carburettor. A solenoid valve (4) associated with the fuel supply selectively controls flow of fuel in which a throttle position sensor (2) generates a throttle closed signal and an engine speed sensor (3) generates a first signal indicative of engine speed above a predetermined threshold speed value and a second signal indicative of engine speed below threshold speed value. In use, when both the throttle closed signal and first signal are generated the solenoid valve (4) is controlled to prevent fuel flow, and whenever the second signal is generated the solenoid valve (4) is controlled to permit fuel to flow to the carburettor.

Abstract: Device which adjusts the combustion of engines during their operations in transitional phases, accelerations, decelerations and changes in the transmission ratios by reduction or suppression of the gas flow through the nozzles of the carburettor, and or by admission, downstream of the carburettor of additional air or exhaust gases, crank-case gases or a mixture of these gases. By its mode of action, the device acts during about75% of the running time of the vehicle in city traffic (case of the ECE 15 cycle). The different embodiments of the device are all characterized by the monitoring system (1-6) controlled by the admission pressure of the engine so that the direction, the intensity and the time of action of the power transmitted to the correcting member (7) be permanently depending on the value of the derivate of that admission pressure with respect to time (POWER = F ((dpa k)/dt) The device may be easily set on any vehicle as an economizer or incorporated in modem combustion systems, conventional or electronic.

Abstract: 　モード切換スイッチ(37)は、エンジン(31)の回転速度をローアイドル状態まで落すローアイドルモードと、アイドリングストップ状態とするアイドリングストップモードとを選択する。ワンタッチローアイドルスイッチ(27)の操作は、ローアイドルモードの場合はローアイドル状態の指令となり、アイドリングストップモードの場合はアイドリングストップ状態の指令となる。コントローラ(32)は、ローアイドルモードにてワンタッチローアイドルスイッチ(27)を操作することでエンジン(31)をローアイドル状態に制御し、アイドリングストップモードにてワンタッチローアイドルスイッチ(27)を操作することでアイドリングストップ状態に制御し、ワンタッチローアイドルスイッチ(27)を再操作することで再始動させる。アイドリングストップ運転を容易に実現できる。

Abstract: The invention relates to a circuit arrangement to reduce fuel comsumption and emission of polluting material of I.C.E. driven vehicles. The pedal clutch, in its upper play range, operates an idle run braking clutch switch (2), thus braking the circuit of electromagnetic idle jet control (1). A starter braking clutch switch (10) is in the direct or indirect operating circuit of the starter (9), which closes the starter circuit when the pedal clutch is pressed deeper than the clutching point of the clutch structure and than the closing point of the idle run braking clutch switch (2).
