<p>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 characterised in that the start of injection (60) is continuously adapted to the prevailing fuel demand and the injection time consequently required, so that the injection D is substantially completed before the inlet valve A towards which the injector is directed will begin to open (50). The control of the start of injection according to the invention provides, by simple means, improved evaporation of the fuel and more homogeneous fuel-air mixture, which in turn provides a more complete combustion and reduced emissions.</p> |
