Abstract

The invention allows for improved engine fuel economy. Restoration of the fuel supply when the engine is powered in the forced xx mode. carried out after selecting the free clutch pedal. If the rotational speed of the crankshaft is below the threshold determined by the device 3 controls, the clutch is turned off after a specified period of time. In the case of a power supply, it is supplied through the switch 5 to the solenoid valve 1 and for a certain time elapsed before the clutch is turned off, the inlet pipe and combustion chambers are filled with combustible mixture.

The invention relates to mechanical engineering, in particular to a method for feeding an internal combustion engine and systems for carrying it out.

The aim of the invention is to improve the fuel economy of an internal combustion engine.

The drawing shows the power supply system for an internal combustion engine; an implementation method.

The power system contains a carburetor with a fuel supply solenoid valve 1, a motorized throttle valve (not shown) and a limit switch 2 associated with the throttle actuator drive. In addition, the system contains a control unit 3 that inputs a signal from the crankshaft speed sensor , which is used as the breaker ignition system. The system is equipped with two limit switches 4 and 5. The first limit switch 4 is connected to the gearbox, and the second switch 5 is connected to the clutch pedal.

The method is carried out as follows.

When the gear is engaged and the clutch pedal is released, after the driver removes his foot from the accelerator pedal, the forced idling mode comes in with the fuel supply turned off. In this case, the electromagnetic valve 1 is de-energized. Forced idling mode continues until the driver again acts on the accelerator pedal or stops the vehicle. In this case, if the rotational speed of the crankshaft of the engine is below the threshold, then the driver must first put his foot on the clutch pedal

Lenin, who, under the weight of his leg, moves away from the stop and first chooses a free move, and then after a certain Bpesr m {for a car with a carburetor, Ozone is 0.5-1.0 s) it is necessary to squeeze the clutch, turn off the gear and at the same time, if necessary, benefit Stop by the brake system. As soon as the driver puts his foot on the clutch pedal, if the engine rpm is below the threshold control unit 3, power will be supplied through switch 5 to the solenoid valve

and for a certain time elapsed before the clutch disengaged, the inlet pipe and the combustion chamber are filled with a combustible mixture, which causes the engine to go into self-idling mode without stopping it. Since, before releasing the clutch pedal, the driver shuts off the transmission and closes the contacts of switch 4, solenoid valve J will be energized without interruption. At engine speed, the threshold clutch can be squeezed out without delay. In this case, the engine does not stall, since the kinetic energy of its rotating parts. It is sufficient to fill the volume of the combustion chamber with a combustible mixture. - When changing gears, the output sensor control unit 3 will turn off the power supply to the solenoid valve 1, and therefore the fuel supply, for almost the entire period that the clutch pedal is depressed and the accelerator pedal is released. In the event of a vehicle moving downhill with the accelerator pedal released during the entire period, the fuel supply will be turned off, regardless of the speed and use of the brake system.
