Abstract
The invention relates to a device and a method which can be applied primarily to computer controlled fuel systems for Otto engines, with sequential injection of fuel in each cylinder to the inlet valves. In order to utilize the capacity of the hot inlet valves for evaporating the fuel, in normal operating cases, the invention is characterized in that the start of injection is continuously adapted to the prevailing fuel demand and the injection time consequently required, so that the injection is substantially completed before the inlet valve towards which the injector is directed will begin to open.
