When the engine speed decreases as the motor pedal 23 is released, as well as in the forced idle mode when the vehicle is braked with the engine, the switch 26 will open the electromagnetic supply circuit to the engine and the gas will be supplied to the engine through the heater 6.

If, after a prolonged stopping of the vehicle, the application of an isothermal balloon exceeds the operating level, the sensor 11 will open the solenoid valve 5 to supply the engine with the vapor phase from the top of the cylinder. This will lead to a rapid decrease in the pressure in the cylinder to the operating level, when reached, the sensor 11 ê. Electromagnetic Clangle 5 V will open the electromagnet, the valve of 3 nodach; g.-gdkoy phase, after which the work system;,. 1t occur as described by Ucii.ie.

When dj, in an isothermal balloon, below the operating magnitude and decrease as a result of iTOi o pressure at the inlet to the second CTVi; eHb of the reducer v, reducing the gas supply to the engine, g / s the next one, can not develop the frequency of rotation required for triggering the indicator 27 and switching on the gas flow through the bypass pipe 24 for hydraulic pressure upstream of the second stage of the reducer. To eliminate this, the sensor is equipped with a sensor 28, vo i opbui NOI pressure reduction, the system below the operating level turns on the electromagnet1: valve 25 and opens an additional gas supply to the inlet of CTVHeiib reducer (torus, regardless of how different it is, including an indicator 27.

With the engine ignition switch, the solenoid valves 3, 5 and 25 are closed: -; Stop the gas supply from cylinder i. When the engine is stopped for any of the reasons and there is no vacuum in the intake manifold, p.

from a closed volume to an isothermal gas cylinder.

In the second embodiment, the gas supply through conduit 24 bypassing the preheater will be performed at a predetermined vacuum in the intake manifold 19, which is a function of the throttle valve position and the frequency of rotation of the engine shaft. In the forced idling mode, as well as when the engine control 23 is released, as a result of an increase in vacuum behind the throttle valve 22, the sensor will open the power supply circuit of the electromagnetic valve Pa 25 and the gas supply to the engine will be conducted through the heater b. Since there is little or little vacuum in the intake manifold when starting the engine, sensor 33 contacts when. this closed. However, the power supply of the electromagnetic valve 25 or more of the e.1 electromagnetic valve 3 prevents gas from entering the second stage of the reducer through pipe 24. if the pressure in the cylinder is at the same level as the working level.

Due to the introduction of an additional pipeline with a solenoid valve installed in it, the proposed system has a quick response, since the flow of heated gas is immediately replaced by a flow of low temperature gas without changing the thermal state of the evaporator and preheater, which usually have a high inertia.
