    • 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 present invention concerns a device for fuel injection intended for an internal combustion engine with a wide range of speeds of revolution and with high requirements for rapid response such as, for example, the engine in a motor cycle, and a method of controlling fuel injection to such an engine. In the invention according to the present application the fuel injection to an internal combustion engine comprising an intake pipe (1) with at least one intake valve (2) and one or more injectors is controlled in such a manner that a first fuel injection in order to obtain a well prepared air/fuel mixture occurs early in the working cycle of the engine following the closure of the intake valve and a second fuel injection in order to obtain an optimal amount of fuel for the cycle, a process known as "transient compensation", occurs late in the working cycle before closure of the intake valve.
