The automatic mixture control can be removed and cleaned if the lead seal at the point of adjustment is not disturbed. Figure 3. The idle needle valve is connected by linkage to the throttle shaft so that it restricts the fuel flowing at low power settings idle range. Knock with a light hammer blows on the blunt edge of the knife, having the knife alternately putting on different sides of the dispenser. The throttle valves may be either rectangular or disk shaped, depending on the design of the carburetor. Unit - II Construction. Ignoring the effect of altitude or ambient air conditions, the use of a positive-displacement, engine-driven pump means that changes in engine nei and li 1979 pdf affect total pump flow proportionally.integral mixture control) and outlet fuel line into a clean, dry container while working the mixture control through its full range of operation. Inspect the flushed fuel. If free from contamination, connect to the throttle and control unit using the appropriate maintenance instructions. If contamination is found, correct the issue before proceeding. c. Flush the fuel transducer hose (where.

Applicability: Fuel control unit LUN all versions which are made / serviced (new made, overhauled, inspected, maintained) in Jihostroj a.s. Velešín between December 02, and September 30, This fuel control unit is installed on M engine see Appendix No.: 1 of Mandatory Bulletin No.: A . The purpose of the fuel control unit is to meter and control the fuel flow to the discharge nozzle. The basic unit consists of three jets and four valves arranged in series, parallel, and series-parallel hookups. [Figure 3] These jets and valves receive fuel under pressure from the regulator unit and then meter the fuel as it flows to the discharge nozzle. The manual mixture control valve. It is used to control the flow of air-fuel mixture to the engine. As the butterfly valve is turned into the accelerate position, the airflow over the jet increases and more fuel is drawn out into the air stream, keeping the mixture strength constant. A second butterfly valve called choke is used to provide a richer mixture for the engine to start in cold condition. The choke controls the. The fuel control unit consists of following major components: condition lever that selects the start, low idle and high idle functions, power lever that selects the gas generator speed between high idle and maximum through which three dimensional cam, cam follower lever, fuel valve, fly weight governor that controls the fuel flow to maintain selected speed, the pneumatic bellows that controls. [Figure 10] The system consists of a fuel injector pump, a control unit, a fuel manifold, and a fuel discharge nozzle. It is a continuous-flow type, which controls fuel flow to match engine airflow. The continuous-flow system permits the use of a rotary vane pump which does not require timing to the engine. Figure Continental/TCM Fuel-Injection System: Fuel-Injection Pump. The fuel pump is. Fuel Control Unit Packaging Procedure 4. Secure Fuel Control Unit to the proper shipping board & attach T1 Sensor to board being careful not to damage the housing or bellows. 5. Install (Pictured in Yellow) Sealing Plate or Governor to insure no extra leakage will happen during shipment. 6. Next insert Fuel Control into the Proper size.
