What is the function of a motorcycle carbon canister?

The function of a motorcycle carbon canister is environmental protection. It recovers the fuel vapor evaporated from the fuel tank to prevent it from being released into the air and causing pollution. The recovered fuel vapor is then sent back to the engine for combustion, which helps save energy. The daily maintenance methods for motorcycles include: 1. During the break-in period, keep the motorcycle idle speed at 100 RPM; 2. Match the gear with the speed; 3. When braking is needed due to an obstacle ahead, release the throttle, step on the rear brake with the right foot, and gently apply the front brake with the right hand. A motorcycle is a nimble and fast means of transportation, powered by a gasoline engine and steered by handlebars to control the front wheel. It can be a two-wheeled or three-wheeled vehicle, known for its agility and speed, widely used for patrolling, passenger and cargo transport, and as sports equipment. A motorcycle consists of an engine, transmission system, running gear, braking system, and electrical instrumentation. The transmission system of a motorcycle is composed of primary reduction, clutch, gearbox, and secondary reduction.
The main function of a motorcycle's carbon canister is to capture the evaporating gasoline vapors from the fuel tank, preventing them from escaping into the air and polluting the environment. I learned while riding that when a bike is parked in hot weather or right after the engine is turned off, gasoline can easily evaporate and form harmful gases. The activated charcoal inside the carbon canister acts like a filter, absorbing these vapors. When the engine starts, the purge valve opens, drawing the vapors into the combustion chamber to be burned, reducing waste and preventing air pollution. If it fails, the fuel tank may expand, emit unpleasant odors, or even affect engine startup. Regular checks on the carbon canister are necessary to prevent aging or clogging, otherwise, it might fail emission tests. When replacing, always opt for original parts to ensure the system remains unobstructed. I've seen some older motorcycles without this component, and the pungent smell reminds me why modern designs are so crucial.
