摘要： Flange assembly (56) for supporting a structure that provides scavenging air supply to an internal combustion engine (40) at the carburetor (42) to the engine. The assembly includes a thin-body flange (58) that is configured to be abuttingly installed upon an end surface (48) of the carburetor. The carburetor has its combustion air intake (50) or port exposed at an outer surface for intaking air for the combustion process. The thin construction of the flange enables advantageous positioning of the adaptive flange. The relative dimensioning of the thin-body flange (58) also contributes to its low-impact as a modification to air inlet arrangement. A combustion air aperture (60) is provided that extends through the thin-body flange. The combustion air aperture (60) is located in the flange for alignment with the combustion air intake. By this alignment, fluid communication is established across the flange and into the carburetor when the flange is abuttingly installed upon the carburetor. A scavenging air aperture (64) also extends through the thin-body flange and is spaced apart from the combustion air aperture. A valve assembly (76) is operatively coupled to the thin-body flange and has a valve element (78) positioned at the scavenging air aperture (64) for opening and closing the scavenging air aperture.

摘要： Method for adjusting the air-fuel ratio of an internal combustion engine (1), in a fuel supply section (8) thereof, such as a carburettor or a fuel-injection system, the fuel supply section (8) comprising means for adjusting the air-fuel ratio of the engine (1), the engine having an engine speed (N) and an engine throttle ranging from zero throttle to full throttle, the method comprising the steps of: a) measuring the engine speed (N) of the engine (1), b) comparing the engine speed (N) to a first engine speed value (NFS I; NiS1) c) if the engine speed (N) is lower than the first engine speed value; the air-fuel ratio is adjusted, d) repeating step a) to c) until the engine speed (N) is either larger than or equal to the first engine speed value (NFS I; N1Si).
摘要翻译：一种用于调节内燃机（1）的空燃比的方法，在燃料供给部（8），例如化油器或燃料喷射系统中，所述燃料供给部（8）包括用于调节发动机（1）的空燃比，发动机转速（N）和发动机节气门从零节气门到全节气门的发动机节气门，该方法包括以下步骤：a）测量发动机的发动机转速（N）发动机（1），b）如果发动机转速（N）低于第一发动机转速值，则将发动机转速（N）与第一发动机转速值（NFS I; NiS1）c）进行比较; 调整空燃比，d）重复步骤a）至c），直到发动机转速（N）大于或等于第一发动机转速值（NFS I; N1Si）为止。
