Abstract
For the electronic control system of a Diesel injection system a smoke pulse limitation device is proposed, so that even during dynamic operational conditions the exhaust gas clouding does not exceed unwanted high values and without requiring sensors for the direct or indirect determination of the amount of air aspirated per cylinder stroke. For this purpose there are proposed a delay element for a signal giving the desired amount of fuel as well as a real differentiator in a rpm signal processing branch. Finally, by way of a performance characteristic data storage for the smoke pulse limiter, maximally permissible fuel amount values are determined.
