Description
Die Leistungsregelung bei Explosionskraftmaschinen, die mit leichtflüssigem Brennstoff arbeiten, geschieht im allgemeinen durch mehr oder weniger starkes Abdrosseln des Gasgemisches, so daß einer verringerten Leistung auch ejn kleinerer Füllungsgrad der Z)'linder entspricht. Hieraus ergibt sich jedoch, daß nur bei Volleistung die höchste zulässige Kompression und damit die höchsteThe power control in explosion engines that use low-viscosity fuel work, is generally done by more or less strong throttling of the Gas mixture, so that a reduced power also ejn smaller degree of filling of the Z) 'linder. From this it follows, however, that the highest only at full power permissible compression and thus the highest
ίο Brennstoff ausnutzung erreicht wird, und daß bei zunehmendem Drosseln des Gasgemisches der spezifische Brennstoffverbrauch ansteigt.ίο fuel utilization is achieved, and that with increasing throttling of the gas mixture, the specific fuel consumption increases.
Vereinzelt wurde auch schon eine RegelungOccasionally, a regulation has also been made

■ 5 fähigen Grenzen vorgenommen. Da diese Grenze jedoch sehr eng bemessen ist, so konnte eine genügend große Kraftverringerung ohne Abdrosseln der Maschine nicht erzielt werden.■ 5 capable limits made. This one However, if the limit is very narrow, a sufficiently large reduction in force could not be achieved without throttling the machine will.
Zweck vorliegender Erfindung ist, die Leistung der Maschine innerhalb der zündfähigen Grenzen zu verändern und diese Grenze möglichst weit auszudehnen, ohne das Gasgemisch abdrosseln zu müssen, so daß auch bei verringerter Leistung die höchste Kompression stattfindet und der spezifische Brennstoffverbrauch geringer wird. Dies wird err reicht durch Qualitätsregelung des Gasgemisches innerhalb seiner zündfähigen Grenzen bei offenem Vergaser (Drosselklappe) in Verbindung mit gleichzeitiger Zündzeitpunktverstellung, so daß bei zunehmendem Luftüberschuß entsprechend frühere Zündung erfolgt. ■Purpose of the present invention is the performance of the machine within the ignitable To change limits and to expand this limit as far as possible without the gas mixture To have to throttle, so that the highest compression even with reduced power takes place and the specific fuel consumption is lower. This will err is sufficient by regulating the quality of the gas mixture within its ignitable limits with open carburettor (throttle valve) in connection with simultaneous ignition timing adjustment, so that with an increasing excess of air, ignition takes place earlier. ■
