9039-IR-EP AN IMPROVED COMBUSTION CONTROL SYSTEM Abstract of the Disclosure The system comprises a zirconium sensor interposed in the exhaust conduit of a gas- fueled engine for sensing both oxygen content and temperature of the exhaust gases, and for emitting electrical analog signals thereof to a comparator/controller. In turn, the latter transmits a complementary, derivative electric- al signal to a current-to-pressure transducer. The transducer is supplied with gas under pres- sure, from the engine fuel (gas) supply line, and the pressure of this transducer-supplied gas is modulated by the aforesaid derivative signal. The modulated gas pressure is communi- cated with a gas cylinder, having a translating piston rod, which is operatively engaged with an otherwise standard gas engine regulator for trimming control of the flow of fuel (gas) through the regulator.
