Opto-Elektronische Steuerung der Auslass-Kanal-Querschnitt-Verstellungseinheit für Zweitakt-VerbrennungsmotorenOpto-electronic control of the exhaust port cross-section adjustment unit for two-stroke internal combustion engines

1. Die Frischgase werden durch Steuerung der am Zylinderkopf befindlichen Einlassventile in den Verbrennungsraum gepumpt, dadurch werden die Altgase nach unten Richtung Auslass-Kanal gedrückt (Spülung).1. The fresh gases are pumped into the combustion chamber by controlling the intake valves on the cylinder head, which pushes the old gases downwards towards the exhaust port (flushing).

2. Der Infrarot-Detektor erkennt ständig die Temperatur im Verbrennungsraum und leitet diese Informationen fortwährend zur Steuereinheit.2. The infrared detector constantly detects the temperature in the combustion chamber and continuously transmits this information to the control unit.

Die Steuereinheit überwacht die Temperaturen und bemerkt sofort, wenn die kalten Frischgase die heißen Altgase ablösen. Diese Informationen werden mit dem Stand des Kolbens verglichen und wenn nicht der optimale Rückstau vorhanden ist, wird der Auslass-Kanal-Querschnitt verändert, sodaß immer die optimale Menge an Altgasen entweichen können aber keine unverbrannten Frischgase.The control unit monitors the temperatures and immediately notices when the cold fresh gases replace the hot old gases. This information is compared with the position of the piston and if the optimal back pressure is not present, the exhaust channel cross-section is changed so that the optimal amount of old gases can always escape but no unburned fresh gases.

3. Eine optimale Energieausnutzung ist damit gewährleistet.3. This ensures optimal energy utilization.

Das ein Sensor die Temperatur im Verbrennungsraum erfaßt und zu einer Steuereinheit leitet, die die verstellung des Auslass-Kanal-Querschnitts steuert.2. A sensor measures the temperature in the combustion chamber and sends it to a control unit which controls the adjustment of the exhaust channel cross-section. 3. Die Altgas-Entsorgung wird durch den Kolben und eine variationsfähige Auslass-Kanal-Querschnitt-Verstellung gesteuert, die immer tür den optimalen Rückstau sorgt.3. The waste gas disposal is controlled by the piston and a variable outlet channel cross-section adjustment, which always ensures the optimal back pressure. Mönchengladbach, den 16.
