Quality adjustment screw (composition) carburetor mixtures 2E2
- 1 - quality adjustment screw (composition) mixtures;
- 2 - adjusting screw of the protrusion of the rod of the pneumatic actuator of the throttle valve of the first chamber
Adjustment is carried out on a warm engine (with fully open air damper) with the correct ignition timing and with the electrical consumers switched off.
Order of execution
1. Connect the control tachometer and gas analyzer in accordance with the manufacturer's instructions.
2. Screw rotation (see fig. Adjusting the engine start speed at the carburetor 2E2) adjust the engine speed within (750±50) min-1.
3. Disconnect the crankcase breather hose.
4. Use the screw to adjust the quality of the mixture to set the level of carbon monoxide (SO) in exhaust gases no more (1,0±0,5) % (when the screw is turned in, the combustible mixture is enriched, when it is turned away, it becomes leaner). Check and, if necessary, restore the idling speed, as well as the CO content in the exhaust gases.
