Starting device
The launcher is intended for enrichment mixture when starting and warming up a cold engine. The device is designed as a valve with switching from the driver's cabin. To prevent an extremely tion of enrichment of a mix air damper can be there is a valve that opens under pressure- eat atmosphere if you experience a significant neg- tion in the mixing chamber of the carburetor after a start of the engine the tell. The driver adjusts the position of the flap with cable, output cab. Simultaneously with the closing choke opens the throttle and gives DWI- Gately to stop. The axis of the air valve installed in the intake Pat- the bridge of the carburettor asymmetrically, so that under the action of pressure difference of air flow on both sides of the damper it tried to open. In this design, the damper the mixture is protected from pereobogaschenie when you start the engine La. At the same time it does not allow the engine to stop, so as the mixture is automatically enriched by reducing the number revolutions of the crankshaft. Balancing of the carburettor prevents the enrichment the combustible mixture in case of clogging of the air filter. With for this purpose the float chamber of the carburetor communicates with the atmosphere through the channel opening to the space above the who- stuffy flap. In this case, the dilution due to clogging of the air filter in equal measure is passed and in the float chamber, eliminating the flow of unwanted top Liwa in a spray bottle. On the engines of domestic cars set Ute-balanced the carburettors float chamber and the incident flow, when the air-fuel mixture moves from the top down. To improve filling and uniform distribution- dividing the combustible mixture in the combustion chambers of the cylinders at change two-chamber carburettors. The main metering the device provides a pneumatic braking top Liva, which compensates the air-fuel mixture. In the case the carburetor has two mixing chambers, each Daya of which nourishes your group of cylinders. Poplavko- Wai's camera, suction socket with air valve, economizer and accelerator pump are common to both cameras and carburetor. A limitation on the maximum frequency of rotation of the knee catego motor shaft domestic cars consists of centrifugal sensor and pneumatic dia- Rahmanova actuating mechanism. The sensor is attached to the lid of the electrical pole- Ren and the rotor is driven in rotation from the dispenser is tion of the motor shaft. The Executive mechanism of the impact- em on the throttle. The mechanism is mounted on the car muratore. The sensor is connected by ducts with the contractor- tion mechanism and the suction port of the carburetor. While the engine speed does not exceed the maximum value, the gauge valve is open and the upper and the lower cavity of the actuating mechanism are reported with a suction nozzle and mixing chamber Kar- buretor. At this time, the mechanism has no effect on Dros- celinie damper. If the engine speed exceeds the value the radiation to which the sensor is adjusted, the valve rotor under centrifugal forces will override the channel access who- spirit in the cavity above the diaphragm. The vacuum transmitted from the mixing chamber, creates power that moves the the diaphragm upward. In this case, through the lever and the rod prikryvat- are the throttle, causing the frequency of rotation. the illumination of the crankshaft exceeds a specified value. In the original position of the device is returned under the action- eat a stretched spring, and throttle p- are. Body parts of carbs are made of Alu- Minevich alloys. To seal the connectors between system Mami carburetor used cardboard or made- nye of benzokolonki rubber strip. Jets, float, strainer and some washers m- Ute of copper or its alloys. The levers, rods, sprayers, re- gulirovanie screws, springs and mounting screws complying with tween of steel, the diaphragm is made of rubber. Increasingly, modern automotive gasoline the power engines are replaced by fuel injection systems of injection of petrol. |
