Title:
SYSTEM OF FEEDING FUEL FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS5413832
Kind Code:
A
Abstract:
The electronically regulated fuel feed system consists of a pneumatic servo piston (17) to measure the air induction flow, a manually operated throttle valve (13) and a magnetically regulated fuel valve (10). The fuel valve is similar to conventional magnetic fuel valves except that the coil which excites the spring loaded armature is made up of a number of parallel circuited windings of low impedance. The windings are connected to electronic circuits responding to engine working conditions. The pneumatic piston is of the type used to regulate the fuel flow in certain carburettors by raising a taper needle. The piston housing (16) has a linear transducer (22) to produce an electrical output which is linear in respect to the servo piston position. The signal from the transducer is used as the principal regulator input signal for the electronic regulator. The fuel injector valve is opened and closed at a frequency determined by engine revolution speed and its opening dwell is determined by engine working conditions.
