System of idling
The idle system consists of the fuel jet idle air jet and therefore of adjusting screw. Under throttle is more retrage- tion, under the influence of which the fuel passes through the putt, ler idling, is mixed with air from air jets and emulsion flows out of the hole Dros- the mudflow. The idle system has two holes: one on top throttle, the other below it. At low speeds kalena- that shaft through the bottom hole flows out of the fuel emulsion- this, and is drawn through the upper air. When you open throttle emulsion enters the chamber shore- tion through both holes, and this is provided by a smooth ne- transition from idle to low loads. Pro- the output section of the lower hole is changed by rotating the adjusting screw. By changing the cross-section of the emulsion- news channel you can change the quality of the supplied combustible mixture: wrapping the adjustment screw to lean out the mixture and twisting is to enrich. The number of incoming combustible mixture adjust stop screw throttle. When screwing screw the throttle is opened, increasing the number of post- vary the mixture, which in turn increases the frequency of rotation. with regard to the crankshaft of the engine. Conversely, if you are vertuani screw the throttle closes, the number of post- out of the mixture decreases, causing decrease- the determination of the number of revolutions of the crankshaft of the engine the tell. The economizer serves to enrich the fuel mixture when full loads and during acceleration when the throttle is is not fully opened. Since the main metering system of the carburetor adjust- holyroman to ensure mixture formation depleted composition, to obtain maximum power ness of the engine requires a richer mixture. This is achieved by using the economizer, when the fuel is supplied the spray not only through the main nozzle, but also through the valve of economizer. The combined effect of the main dosiro- the host system and the economizer provides enriched the mixture required to obtain maximum capacity engine. The economizer consists of a valve, which is pushed against the seat spring, nozzle and components of the drive. The drive lever cluster Mr. economizer is fixedly mounted on the axis of the choke Noah damper. The valve is triggered when the throttle p- is more than 3/4 full, and provides extra hearth- Chu fuel to the nozzle. Accelerator pump serves to enrich the combustible mixture during sudden throttle opening, that is important but to ensure the responsiveness of the engine, that is who possibilities sharp transition from small loads to large. With a sharp throttle increase the amount of incoming air into the mixing chamber is much faster than the flow of fuel through putt- Lera and sprays, which leads to a drastic depletion the fuel mixture and may cause engine stop. In order to avoid this, it is necessary to provide forced the injection of gasoline into the mixing chamber for short temporary enrichment of the combustible mixture. Accelerator pump is out of the well, I- ka, plank, pull, lever, discharge check cluster- Panov. With a sharp opening of the throttle spring is compressed, and the piston rapidly moving down, the pressure on the fuel. About- razuysya the hydraulic impact of fuel closes the appli- tion and opens discharge valves. Fuel through the spray enters the mixing chamber. Spring, rasimas, continues to move the piston down in 1-2 s, which provides a longer time bedrooms injection of an additional portion of fuel. |
