Operating mode

PWK 28MM Carburetor is a carburetor that works based on the vacuum principle. Its working mode mainly involves the following steps:


Mixed gas entry: When the engine is working, the piston moves downward, forming a negative pressure in the cylinder. At this point, the throttle valve in the PWK 28MM Carburetor opens, allowing air to pass through the air filter and into the carburetor.


Fuel Injection: As air flows in, fuel is injected from the carburetor's fuel injector into the air flow to form a mixture.


The mixture enters the cylinder: The mixed air and fuel enter the engine cylinder, waiting for ignition and combustion.


Ignition combustion: The mixture is ignited and burned in the cylinder, generating energy that pushes the piston downward.


Exhaust gas emission: The burned exhaust gas is discharged from the cylinder through the exhaust valve and circulates for the next round of work.


Through these steps, the PWK 28MM Carburetor can ensure that the engine receives the proper amount of mixture to ensure normal engine operation and provide the required power output.
