    • Method for controlling a fuel valve and/or an air valve supplying fuel or air respectively to a crank case scavenged internal combustion engine (1) comprising means for controlling said valve used for a supply system for combustible mixture to the engine, such as a carburettor (9) or a fuel injection system. The valve is controlled in consecutive periods of revolutions each having a period length (PL) of at least 10 revolutions. For each period a valve control sequence (N s /PL) is determined, providing a number (N s ) of valve shut-off positions (FCn) determining which particular revolutions in its corresponding period the valve is to be closed, where the number (N s ) of valve shut-off positions (FCn) corresponds to the amount of fuel or air respectively to be supplied to the engine (1) during the corresponding period.

    • The invention concerns a method for controlling at least one of a fuel supply and an air supply to an internal combustion engine (1), in a fuel supply section thereof, such that an A/F-ratio is adjusted automatically to a desired level. Moreover, the method is activated at a speed close to a cut-out speed threshold(52) where the engine speed will fluctuate around the threshold (52) and the method comprises the steps of : - receiving engine speed data on rotational speed from the engine (1), - briefly changing the A/F ratio, - comparing engine speed data that are essentially unaffected by the brief change to engine speed data that are affected by the brief change to evaluate the impact on the engine speed fluctuation resulting from the brief change, - adjusting the A/F ratio in the same direction as the brief change if the engine speed data affected by the brief change indicates an increase in acceleration after combustion/s, and - adjusting the A/F ratio in the opposite direction to the brief change if the engine speed data affected by the brief change indicates a decrease in acceleration after combustion/s.
    • 本发明涉及一种用于控制其燃料供应部分中的内燃机(1)的燃料供给和空气供应中的至少一种的方法,使得A / F比自动调节到期望水平。 此外,该方法以接近切断速度阈值(52)的速度被激活,其中发动机速度将围绕阈值波动(52),并且该方法包括以下步骤: - 从转速阈值(52)接收关于转速的发动机转速数据 发动机(1), - 简要地改变A / F比, - 将基本上不受短暂变化影响的发动机转速数据与受短暂变化影响的发动机转速数据进行比较,以评估对由 如果发生短时间变化影响的发动机转速数据表明燃烧后的加速度有所增加,则调整A / F比率与短时间相同的方向调整A / F比,并且相反方向调整A / F比 如果受短暂变化影响的发动机转速数据表明燃烧/ s后的加速度下降,则进行简要更改。
