IMPROVING THE FUEL ECONOMY OF CARGO CARS WITH CARBURETTIC ICE IN MODE INDIVIDUAL IDEAL PROCESS

Abstract

To improve the fuel efficiency of trucks with gasoline carburetor internal combustion engines in self-idling mode, a device has been developed that ensures automatic engine operation by periodically repeated short-term cycles consisting of alternating shutdown cycles and fuel (or an fuel-air mixture) switching cycles through the output channel of idle carburetor system in the field of low frequencies of rotation of the cranked shaft (c.s.). The device consists of an electronic control unit (ECU), an electrical- pneumatic valve, a sensor of rotation velocity of c.s. of ICE, accelerator sensor and gearshift lever neutral sensor, electrically interconnected and with the power source by electrical wires through plug connectors. The ECU block is located in the cab of the car and is powered by direct current from the electrical system on board. It includes a voltage regulator, a signal amplifier, a one-shot (Schmidt trigger), a microcontroller, and a power switch (toggle switch).
