TWO-FUEL ENGINE CONTROL SYSTEM Russian patent published in 2014 - IPC F02D19/06 F02D41/02 F02M21/02

Abstract RU 2504679 C2

FIELD: engines and pumps.

SUBSTANCE: proposed control system comprises ignition system with N-channel distributor wherein N is the number of cylinders, liquid fuel feed system (LFFS) and gas fuel feed system (GFFS). Fuel changeover is performed by fuel changeover switch. LFFS is composed of carb feed system with first idling economiser and electronic control. GFFS comprises gas cylinder with feed control valve, differential gas control valve and N-fast-action solenoid valves. Control is performed by integral microprocessor control unit. Said control system comprises has temperature gage, absolute pressure gage, waste gas composition transducer, coolant temperature transducer and spark formation moment gage. Control system forms optimum composition of fuel-air mix and advance angle at all ICE operating conditions at using both liquid and gas fuels.

EFFECT: higher operating efficiency.
