摘要:
What follows is the description of an apparatus for use with a combustion engine which has a plurality of working cylinders with which there are associated a plurality of injection valves. The apparatus includes in combination with a fuel tank, a pump, a fuel control pipe, an amplifying resistance, a differential pressure regulator, a plurality of parallel-connected metering regulators and a plurality of metering resistances, a device which in conjunction with the other stated elements and which is positioned within an air intake channel continually measures and individually distributes to the plurality of fuel injection valves the amounts of fuel appropriate to the amounts of combustion air passing through the intake channel.
摘要:
A fuel injection control device comprising pluralities of second pulse generators in addition to a first pulse generator between a pulse distributor and respective fuel injection valves. The second pulse signal is added to the first pulse signal to produce a sum signal thereof, and the pulse width of each pulse is controlled by a single pulse width control circuit common to the respective fuel injection valves, thereby to control each of the injection valves to actuate for a period of time properly determined depending upon the operational state of the engine. Each of the injection valves can operate continuously and the injection period of one fuel injection valve can overlap that of a following fuel injection valve.
摘要:
An electro-magnetic torque motor has a permanent magnet pivotally mounted in a hollow frame of magnetisable material. Surrounding the magnet within the frame is a winding whose magnetic axis is angularly displaced from the magnetic axis of the magnet when the winding is not energised. Energisation of the winding tends to rotate the magnet within the winding in a direction to align the magnetic axes.
摘要:
An internal combustion engine of the fuel injection type having a main fuel injection nozzle for normal running of the engine, a starting fuel injection nozzle for starting or warming up of the engine, means for adjusting the amount of fuel injected with said main nozzle respondingly to negative pressure in the interior of an intake pipe downstream of a throttle valve, means for increasing fastly the amount of fuel injected with said main nozzle independently of said means for adjusting the amount of fuel and allowing to inject supplementary fuel with said starting fuel injection nozzle in low temperature condition of the engine, means for adjusting continuously the amount of the supplementary fuel manually or automatically with the operation of a temperature sensitive member settled on a proper portion of the engine.
摘要:
An apparatus of the type in which the amount of fuel injected to an internal combustion engine is controlled by a control member arranged to be moved with a front wall urged forwardly by a return spring and rearwardly by negative pressure in a negative pressure chamber connected to an air intake passage of the internal combustion engine. A second negative pressure chamber is provided behind the foregoing negative pressure chamber and the foregoing return spring is supported by a second front wall, which is urged forward by a second return spring in the second negative pressure chamber, the interior of the second negative pressure chamber being selectively connected to the atmosphere and the air intake passage of the engine through a change-over valve.
摘要:
A mass flow, timed fuel injection system is provided, wherein fuel flow is maintained at all times in a predetermined relation to air mass flow actually entering the engine at any instant, and the fuel injection valve is maintained open for an interval corresponding to a constant crank angle. This interval is corrected to compensate for any error which may have occurred because of inaccuracies introduced by the venturi through which air is metered and to compensate for the variations in discharge nozzle downstream pressure that occur in the induction ports.
