Emission Control Carburetor Choke Pull-Off
Item Name Code (INC) 36489
 |
An item designed to monitor engine vacuum to feather the choke opening in response to engine requirements, preventing stalls and hesitation from over-choking.
Additional Information for Emission Control Carburetor Choke Pull-Off
Emission Control Carburetor Choke Pull-Offs are components of the engine fuel system that are used in non-aircraft engines. They are part of the engine accessories supply group.
The purpose of the choke pull-off is to control the operation of the choke on a carburetor. The choke is responsible for regulating the air-fuel mixture during engine startup, ensuring proper fuel atomization and combustion.
The choke pull-off is typically connected to the choke linkage and vacuum source. When the engine is started, the vacuum from the engine creates a pull on the choke pull-off, which releases the choke plate, allowing more air to enter the carburetor and lean out the air-fuel mixture. This prevents the engine from running too rich during warm-up and helps reduce emissions.
Overall, the emission control carburetor choke pull-off plays a crucial role in optimizing engine performance and reducing harmful emissions in non-aircraft engines.
