Title: Piezoelectric fuel injector control for Diesel engine - provides separate HV DC generator units and storage capacitors with microprocessor control, for pre. and main injections
Inventor: KOZAWA KIYOMITSU
IPC: F02M45/04
Filed: 1989-10-27
Abstract: Injectors for individual cylinders are driven by piezo-electric elements under the control of a microprocessor in which timers of pre-injection and main injection routines operate in conjunction with a program memory and write/read memory for time-varying data. An input/output interface receives signals from two crankshaft position detectors and supplies commands to a thyristor ignition circuit.  Analogue signals from inlet manifold pressure and  coolant temp. sensors and a throttle opening sensor are digitised for processing by the CPU.  Anomalous operation of the control circuit and other elements is indicated by warning lamps. ADVANTAGE - Main injection and preinjection conditions are stabilised without interaction even when interval between them is shortened. Stalling is averted in anomalous conditions of power supply.
