Abstract

The system has a fuel injector (16) arranged precisely to meter fuel and accurately to time the start and, preferably, duration of fuel injection in response to a multiplicity of engine operating parameters through a control means (74) which controls energisation of a solenoid (6) to control opening of a valve (68, 84, 86) leading from an accumulator chamber (36) pressurised by an independent pump (30). <IMAGE>
