Abstract
A method and apparatus for improving the acceleration behavior of a self-igniting internal combustion engine driven with an exhaust turbocharger by displacing the onset of injection during the acceleration phase toward 'early', and a combustion chamber pressure is attained, which at least in part compensates for reduction in engine power caused by sluggishness of the turbocharger and a resultant smaller cylinder charge. Further increase in power is attained by means of an increase in the fuel component made possible by the adjustment of injection onset without exceeding the smoke limit of combustion. Apparatus are furthermore proposed for performing the method according to the invention, in which with the aid of an acceleration signal obtained by hydraulic or electric elements an adjustment toward 'early' is effected in a hydraulically functioning injection adjustment device.
