Abstract
Fuel delivery system for internal combustion engines and method of delivering fuel by the automatic selection and use of different sections of the fuel pumping ramp of a cam mechanism within the system to control the rate of fuel injection by varying and shaping injection pressure waves or pulses to match engine air intake flow for different engine speed and load conditions. A solenoid operated fuel delivery valve is employed for controlling fuel timing and quantity by commands from a microprocessor with inputs which includes torque demand, engine speed, cam mechanism position and solenoid current regulator signals.
