Fuel feeder for car mounting automatic speed change gear

Abstract

Abstract PURPOSE: To reduce the speed changing shock when performing the shift up, by lowering the fuel pressure during the shift-up to reduce the fuel supply thereby reducing the engine output and suppressing the peak torque low. CONSTITUTION: Upon the shift-up of an automatic speed change gear from second speed to third speed, 2-3 shift switch 19 is turned off while the signal from the switch 19 is provided to an inverter 26a and an AND gate 26b to produce a H level signal. It is provided to a NOR gate 25b then a H level signal produced at the gate C' of the NOR gate 25b is lagged by time T 1 through a delay circuit 26 and outputted, to lower the fuel pressure and to suppress the peak torque even when performing the shift-up of the fuel pressure lowering time to third speed. Consequently the speed change shock can be reduced. COPYRIGHT: (C)1981,JPO&Japio
