Abstract: A fuel system for a fuel injected engine includes a manifold for supplying actuating fluid to a plurality of fuel injectors and an accumulator in fluid communication with the manifold. The accumulator is charged while the engine is running by an actuating fluid pump coupled to the manifold. After the engine has been shut off and a particular engine condition is detected, actuating fluid is supplied to the manifold by the accumulator to fill voids left by contracting actuating fluid.

Abstract: An energy management system for a hybrid vehicle having wheels drivingly connected to traction motors, which motors are alternatively energized by an internal combustion engine generator or an electrical storage battery. The system comprises an electrical storage battery, a high voltage electrically heated catalyst (300-400 volts) for treating the exhaust gas of the internal combustion engine, a generator driven by the selective operation of the internal combustion engine to energize the traction motors and to sometimes produce electrical energy in excess of that consumed by the traction motors, and a high voltage controller for selectively transferring electrical energy generated by the internal combustion engine generator and the electrical energy produced by the traction motors when driven by the wheels to preferentially the electrically heated catalyst and secondarily to the storage battery.
