Abstract

Each unit consists of two cylinders (2) which are slotted out at their bottom dead centre and are each linked by channel (3) to an exhaust turbine (5) driven by the respective cylinder now at the end of its combustion stroke. The turbine (5) is fitted out with two wheels (9) for each channel and fixed in parallel on an output shaft. Each unit piston (1) is driven in the same position by a crankpin and are thus in the same setting in each respective cylinder. The two cylinders per unit work out of phase, thus the piston of one unit cylinder is at the end of its intake stroke as the other unit cylinder piston is at the end of its combustion stroke.

Description

Die Anmeldung bezieht sich auf Viertaktdieselbrennkraftmaschinen, mit oder ohne Aufladung und ist eine Zusatzanmeldung zu der Patentanmeldung Aktenzeichen 196-10-144.1-13.The application relates to four-stroke diesel engines, with or without supercharging an additional application to the patent application file number 196-10-144.1-13.

Dieser Zusatzanmeldung zu der obengenannten Patentanmeldung liegt die Überlegung zugrunde, daß man jeden Zylinder einer Funktionseinheit mit einem eigenen Kanal (3) (Abb. 2) und einem zugeordneten Turbinenrad (9) (Abb. 2) ausstattet.This additional application to the above-mentioned patent application is based on the consideration that each cylinder of a functional unit is equipped with its own channel ( 3 ) ( Fig. 2) and an associated turbine wheel ( 9 ) ( Fig. 2).

Als Ergebnis würde sich eine optimale Ausnutzung der Energie, welche in den Abgasen am Ende des Verbrennungstaktes noch vorhanden ist, ergeben. Bei aufgeladenen Motoren würde je nach Ladedruck von dem Zylinder welcher sich am Ende des Ansaugtaktes befindet, Frischluft in den Abgaskanal übertreten und sich nach dem Passieren der Abgasturbine mit den dort vorhandenen Abgasen des jeweils anderen Zylinders einer Funktionseinheit vermischen und durch die Zufuhr der Frischluft eine Verbrennung der dort noch vorhandenen Treibstoffreste ermöglichen, dadurch würde sich der Schadstoffanteil in den Abgasen verringern.As a result, there would be optimal use of the energy in the exhaust gases at the end of the day Combustion cycle is still present. With turbocharged engines, depending on the boost pressure fresh air from the cylinder located at the end of the intake stroke into the exhaust duct violate and after passing the exhaust turbine with the exhaust gases present there mix each other cylinder of a functional unit and add one by supplying fresh air Allow combustion of the remaining fuel there, which would Reduce the amount of pollutants in the exhaust gases.

Claims (1)

Viertaktdieselbrennkraftmaschine mit oder ohne Aufladung deren Zylinderzahl durch 2 teilbar ist, dadurch gekennzeichnet, daß immer zwei nebeneinanderliegende Zylinder einer Funktionseinheit angehören. Diese Funktionseinheit hat die weiteren Merkmale, daß die beiden Zylinder im unteren Totpunkt durch Schlitze durchbrochen sind und jeder Zylinder über einen Kanal (3) (Abb. 2 und 3) mit einer Abgasturbine (5) (Abb. 3) verbunden ist, welche von den Abgasen des sich am Ende des Verbrennungstaktes befindenden Zylinders angetrieben wird. Diese Abgasturbine muß mit zwei getrennten Turbinenrädern eines für jeden Kanal, welche gleichlaufend auf einer Abtriebswelle befestigt sind ausgestattet sein (9) (Abb. 2). Ein weiteres Merkmal einer Funktionseinheit besteht darin, daß jeder Kolben einer Funktionseinheit von je einem Kurbelzapfen in gleicher Stellung angetrieben wird und sie sich deshalb in beiden Zylindern immer in der gleichen Stellung befinden. Die beiden Zylinder einer Funktionseinheit müssen im Takt versetzt arbeiten. Das heißt der eine Kolben im Zylinder einer Funktionseinheit befindet sich am Ende des Ansaugtaktes und der andere am Ende des Verbrennungstaktes (Abb. 1). Bei der nächsten Umdrehung ist die Situation umgekehrt.Four-stroke diesel engine with or without supercharging whose number of cylinders is divisible by 2, characterized in that two cylinders lying side by side always belong to one functional unit. This functional unit has the further features that the two cylinders are broken through at the bottom dead center by slots and each cylinder is connected via a channel ( 3 ) ( Fig. 2 and 3) to an exhaust gas turbine ( 5 ) ( Fig. 3), which of the exhaust gases of the cylinder located at the end of the combustion cycle is driven. This exhaust gas turbine must be equipped with two separate turbine wheels, one for each channel, which are fixed in unison on an output shaft ( 9 ) ( Fig. 2). Another feature of a functional unit is that each piston of a functional unit is driven by a crank pin in the same position and therefore they are always in the same position in both cylinders. The two cylinders of a functional unit must work in a clocked manner. This means that one piston in the cylinder of a functional unit is at the end of the intake stroke and the other at the end of the combustion stroke ( Fig. 1). The situation is reversed at the next turn.
