Abstract

To avoid troublesome vibrations, as for instance those which occur in standard Otto engines, the new internal combustion engine operates on the opposed-piston principle. The opposed pistons produce complete mass balancing, giving absolutely smooth running of the engine. Moreover, the pre-compression piston and the two-stroke timing eliminate the need for unnecessary and fault-prone timing mechanisms such as valves and cam shafts. As a result, higher reliability and efficiency of the internal combustion engine is achieved. By virtue of the spherical combustion chambers and the controlled diaphragm in the fresh-air duct, combustion can be optimised in all engine-speed and load ranges, thereby reducing pollutant emissions to the minimum. The main application will be to use the engine to drive passenger vehicles and lorries or commercial vehicles.

Description

Die Kolben 1 und 1′ haben Luft verdichtet. Die Einspritzdüse spritzt Kraftstoff ein, welcher sich entzündet. Durch die Verbrennung werden die beiden Kolben in Richtung UT getrieben.The pistons 1 and 1 'have compressed air. The injector injects fuel, which ignites. The combustion drives the two pistons towards the bottom of the barrel.

Gleichzeitig bewegt sich der Vorverdichterkolben 3 in Richtung OT und verdichtet die angesaugte Luft. Der Kolben 4 bewegt sich in Richtung UT und saugt über den Einlaßkanal neue Luft an.At the same time, the pre-compressor piston 3 moves in the TDC direction and compresses the intake air. The piston 4 moves in the direction of UT and sucks in new air via the inlet duct.

Die beiden Arbeitskolben 2 und 2′ bewegen sich in Richtung OT und verdichten die über den Vorverdichterkolben 4 ein geströmte Luft in einen kugelförmigen Brennraum. Kurz bevor die Kolben 2, 2′ den oberen Totpunkt erreicht haben, öffnen sich die Überströmkanäle im Zylinder 1, und die über dem Kolben 3 vorverdichtete Luft strömt in den Zylinder und treibt das verbrannte Gemisch in die Auslaß kanäle.The two working pistons 2 and 2 'move towards TDC and compress the flow of air through the pre-compression piston 4 into a spherical combustion chamber. Shortly before the pistons 2 , 2 'have reached top dead center, the overflow channels in cylinder 1 open, and the air compressed above piston 3 flows into the cylinder and drives the burned mixture into the outlet channels.

Wenn die Kolben 2 und 2′ den OT erreicht haben und Kraft stoff eingespritzt wird, entsteht eine Verbrennung und treibt diese auseinander.When the pistons 2 and 2 'have reached TDC and fuel is injected, combustion occurs and drives them apart.

Folglich bewegen sich die Kolben 1 und 1′ zusammen, schließen die Kanäle, verdichten die unverbrauchte Luft, und der Vorgang wiederholt sich.Consequently, the pistons 1 and 1 'move together, close the channels, compress the unused air, and the process is repeated.

Claims

Counter-piston internal combustion engine with pre-compression piston and 2-cycle flushing to drive automobiles and Commercial vehicles.

The counter-piston design makes it one hundred percent Mass balance achieved, which runs a smoother Motors results.

Furthermore, the pre-compressor piston can be sufficiently large dimensioned to with the membrane controlled Flushing to achieve optimal combustion what in turn keeps fuel consumption low. In addition, the engine "processes" through the spherical Combustion chamber high combustion temperatures, so that with the controlled fresh air addition of pollutant emissions can be regulated precisely in each work area.
