Abstract

PURPOSE: To control the solenoid valve with O2 sensor in the exhaust gas system, installing slow-use solenoid valve having needle to fix passage sectional area of slow fuel inserting into the slow jet.
CONSTITUTION: O2 sensor 13 is installed to the exhaust pipe 12 of LPG engine, the signal of sensor 13 is transmitted to the module 14. Slow-use solenoid valve 15 having a needle 24 to correspond to slow jet 7 installed to the slow path 8 is installed. This slow-use solenoid valve 15 is controlled by output from module 14, when air fuel ratio of mixture is low, time ratio to advance the needle 24 is increased, when air fuel rati is high time ratio to return the needle 24 is increased to control fuel flow so that proper air fuel ratio control can be carried out at low speed running.
