Abstract
Certain reciprocating piston internal combustion engines have liquid oxidant and liquid fuel injection schedules that are controlled by a microprocessor that acts upon pre-stored data and upon engine sensor output data. For these engines, the present invention provides a pressure sensor in the working cylinder combustion chamber whose output controls the injection initiation times.
