Abstract

An air/fuel supply system for an internal combustion engine using liquefied gaseous fuel comprises a solenoid operated fuel injector 18 which injects a controlled quantity of the fuel in a liquid state into a mixing region 26 of the induction system. A control system monitors the cooling effect of the vapourising fuel by measuring the temperature difference between a pair of temperature sensors 44, 46, respectively upstream and downstream of the mixing region and compares the measured temperature difference against a preset reference level to derive an error signal. The error signal is applied to control the fuel injector and regulate the fuel supply to maintain the temperature difference and thus the air/fuel mixture ratio constant. The reference level may be adjusted by monitoring other parameters or operating characteristics e.g. intake air humidity, exhaust gas composition or firing voltage values, to determine and hold the optimum setting of the air/fuel ratio. <IMAGE>
