<p>The system comprises a zirconium sensor (12) interposed in the exhaust conduit (14) of a gas-fueled engine (16) for sensing both oxygen content and temperature of the exhaust gases, and for emitting electrical analog signals thereof to a comparator/controller (22). In turn, the latter transmits a complementary, derivative electrical signal to a current-to-pressure transducer (26). The transducer (26) is supplied with gas under pressure from the engine fuel (gas) supply line (28), and the pressure of this transducer-supplied gas is modulated by the aforesaid derivative signal. The modulated gas pressure is communicated with a gas cylinder (34), having a translating piston rod (96), which is operatively engaged with an otherwise standard gas engine regulator (36) for trimming control of the flow of fuel (gas) through the regulator (36).</p> |
