ABSTRACT:
A compensator scheme is described to compensate variable pressure gasoline injection systems, used on four stroke cycle gasoline engines, for variations of engine speed and intake manifold pressure. The intake manifold pressure compensator adjusts the compression ratio of the gas pressure cycling means of the variable pressure injection system. The engine speed compensator adjusts the ratio of liquid injection pressure to gas pressure in the gas pressure cycling means. Both compensators can be corrected by use of feedback from an engine exhaust gas composition sensor.
