摘要： An evaporative emissions control system for small internal combustion engines, including a charcoal canister which is in fluid communication with the air space above the liquid fuel within the carburetor of the engine and the air space above the liquid fuel within the fuel tank of the engine. The charcoal canister contains charcoal media, and when the engine is not running, fuel vapors from the carburetor and the fuel tank migrate to, and are trapped within, the charcoal media of the charcoal canister. The charcoal canister may comprise a separate component, or may be integrally formed with an engine component such as the air cleaner, the carburetor, or the body of the fuel tank, for example. During running of the engine, vacuum within the carburetor induces a flow of atmospheric air through the charcoal canister to purge the collected fuel vapors from the charcoal media, and the fuel vapors pass into the engine for consumption. In another embodiment, an evaporative emissions control system including a charcoal canister is provided for an engine which includes a fuel injection system.
摘要翻译：一种小型内燃机的蒸发排放控制系统，包括一个与发动机的化油器内的液体燃料上方的空气空间以及发动机燃油箱内的液体燃料上方的空气空间流体连通的木炭罐。木炭罐包含木炭介质，当发动机不运行时，来自化油器和燃料箱的燃料蒸汽迁移到炭罐的木炭介质中并被捕获。炭罐可以包括单独的部件，或者可以与例如空气滤清器，化油器或燃料箱的主体的发动机部件一体地形成。在发动机运行期间，化油器内的真空度通过木炭罐引起大气空气的流动，以从煤炭介质中吹扫所收集的燃料蒸汽，燃料蒸汽进入发动机以进行消耗。在另一个实施例中，为包括燃料喷射系统的发动机提供包括炭罐的蒸发排放控制系统。
