Title:
FUEL SUPPLY DEVICE AND FUEL SUPPLY METHOD
Document Type and Number:
WIPO Patent Application WO/2016/167174
Kind Code:
A1
Abstract:
A fuel supply device for supplying fuel to within the combustion chamber of an internal combustion engine is equipped with a linear actuator, a reciprocating pump which is provided with a pressurizing piston driven by the linear actuator and reciprocating in the axial direction and which alternately repeats the intake of fuel and the discharging of fuel pressurized more than during intake by means of the reciprocation of the aforementioned pressurizing piston in the axial direction, and a controller for controlling the driving of the aforementioned linear actuator, the controller controlling the linear actuator such that, when A (A>0) is the stroke range of the aforementioned pressurizing piston reciprocating in the axial direction and T is the reciprocating period, the maximum value of the absolute value of the acceleration rate for increasing the absolute value of the speed of the pressurizing piston when the reciprocating pump draws in the fuel is less than A∙(2π/T)２, and such that the maximum value of the absolute value of the acceleration rate of the aforementioned pressurizing piston when the reciprocating pump discharges the fuel is more than A∙(2π/T)２.
