Abstract

A pre heater chest (2) is fitted below the inlet manifold (3) and extends beyond the two centre inlet pipes (4, 5). The pre heater chest is connected by two pipes (6, 7) to two channels (8, 9) formed across the cylinder head to joim the exhaust manifold on the opposite side whereby the one channel is a flow channel (8) and the second channel (9) acts as a return. The flow exhaust manifold pipe is provided with a restrictor section (12) to retard or act as a counter pressure to the exhaust gas flow passing through the pre heater chest. A gas temperature dependent valve (13) progressively closes the exhaust gas flow channel as the engine approaches working temperature.

Description

Hubkalben-Brennkraftmaschine mit Saugrohrvorwärmung Die Erfindung betrifft eine Hubkolben-Brennkraftiaschine mit Saugrohrvorwärmung, bei der Abgase aus einem Auslaßstutzen durch einen Kanal im Zylinderkopf in einen Vorwärmkasten am Sammelsaugrohr und von dort durch einen zweiten Kanal zur Auspuffseite zurUckgeleitet werden Bei derartigen Saugrohrvorwärmungen befindet sich im Aus laßstutzen eine verstellbare Stauklappe, mit der ein Gegendruck erzeugt wird, der einen Teil der heißen Abgase in den Kanal im Zylinderkopf umlenkt. Die Anordnung dieser Stauklappen im Auslaßstutzen wird jedoch mit zunehmender Betriebszeit störanfälliger, da die Stauklappenlagerung dem vollen heißen Abgasstrom ausgesetzt ist. Durch Verzundern oder Verbrennen ist ein Festfressen bzw. Ausschlagen der Lagerteile nach einer gewissen Betriebsdauer kaum zu vermeiden.Reciprocating internal combustion engine with intake manifold preheating The invention relates to a reciprocating internal combustion engine with intake manifold preheating in which exhaust gases from an outlet port through a duct in the cylinder head into a preheating box at the manifold and from there back through a second duct to the exhaust side With such intake manifold preheaters there is a lasspipe in the off adjustable baffle flap with which a counter pressure is generated, which is part of the redirects hot exhaust gases into the duct in the cylinder head. The arrangement of these storage flaps in the outlet connection is more prone to failure with increasing operating time, since the Storage flap storage is exposed to the full hot exhaust gas flow. By scaling or burning is a seizure or knocking out of the bearing parts after a certain amount of time Operating time can hardly be avoided.

Aufgabe der vorliegenden Erfindung ist es somit, Mängel dieser Art an bekannten Ausfilhrungen zu beseitigen und Maßnahmen zu treffen, die eine Beeinträchtigung der Funktionsfähigkeit der steuerbaren Vorwärmung auch bei Vollbeaufschlagung ausschließen.The object of the present invention is therefore to remedy shortcomings of this type to eliminate known Ausfilhrungen and to take measures that an impairment exclude the functionality of the controllable preheating even with full admission.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, daß im Auslaßstutzen eine unveränderbare Querschnittsverengung und vor dem oder im Vorwärikasten ein temperaturgesteuertes Ventil angeordnet sind.The object is achieved according to the invention in that in the outlet nozzle an unchangeable cross-sectional constriction and in front of or in the preheating box temperature-controlled valve are arranged.

In vorteilhafter Ausgestaltung kann das Ventil von der Kühlwassertemperatur beeinflußbar sein.In an advantageous embodiment, the valve can depend on the cooling water temperature be influenced.

In der Zeichnung ist der Erfindungagegenstand anhand eines Ausführungsbeispieles schematisch dargestellt und im folgenden näher beschrieben.In the drawing, the subject of the invention is based on an exemplary embodiment shown schematically and described in more detail below.

Eine Hubkolben-Brennkraftmaschine 1 mit in Reihe angeordneten Zylindern ist auf der Saugrohrseite mit einem Vorwärmkasten 2 versehen, der auf der Unterseite des Sammelsaugrohres 3 angegossen ist und sich über zwei Saugrohrstutzen 4 und 5 erstreckt.A reciprocating internal combustion engine 1 with cylinders arranged in series is provided with a preheating box 2 on the suction pipe side and the one on the underside of the collecting suction pipe 3 is cast on and extends over two suction pipe sockets 4 and 5 extends.

Dieser Vorwärikasten 2 ist über Verbindungsleitungen 6, 7 mit im Zylinderkopf angeordneten Kanälen 8, 9 verbunden, von denen der als Vorlauf dienende Kanal 8 von einem gegenüber der Saugrohrseite liegenden Auslaßstutzen 10 abzweigt, während der als Rücklauf dienende Kanal 9 in einen Auslaßstutzen ii mündet.This preheating box 2 is in the cylinder head via connecting lines 6, 7 arranged channels 8, 9, of which the channel 8, which is used as a flow branches off from an outlet connection 10 located opposite the intake pipe side, while serving as a return channel 9 opens into an outlet connection ii.

In dem Auslaßstutzen 10 befindet sich eine Querschnittsverengung 12, die auf die aus dem Einlaßkanal ausströmenden heißen Abgase einen Gegendruck ausübt, durch den ein Teil der Abgase durch den Kanal 8 über ein in der Verbindungsleitung 6 angeordnetes temperaturgesteuertes Ventil 13 in den Vorwärmkasten gelangt und von dort aus über die zweite Verbindungsleitung 7 und den Kanal 9 in den Auslaßstutzen 11 zurückgeleitet wird.In the outlet connection 10 there is a cross-sectional constriction 12, which exerts a counter pressure on the hot exhaust gases flowing out of the inlet duct, through which a part of the exhaust gases through the channel 8 via one in the connecting line 6 arranged temperature-controlled valve 13 arrives in the preheating box and from there via the second connecting line 7 and the channel 9 into the outlet nozzle 11 is returned.

Das Ventil 13 wird von der Kühlwassertemperatur derart beeinflußt, daß mit zunehmender Temperatur sich das Ventil 13 weiter schließt. Bei Erreichen einer bestimmten Temperatur wird schließlici der Abgasdurchlaß vollständig unterbrochen.The valve 13 is influenced by the cooling water temperature in such a way that that with increasing temperature the valve 13 closes further. Upon reaching a certain temperature is finally the exhaust gas passage completely interrupted.

Mit dieser einfachen und wirkungsvollen Saugrohrvorwäruung ist ein völlig geräusch- und störungsfreier Betriebsablauf trotz höchster Beanspruchungen durch auftretende Druckschwankungen sowie durch heiße Abgasströme gewährleistet.With this simple and effective Saugrohrvorwäruung is a Completely noise-free and trouble-free operation despite the highest demands guaranteed by pressure fluctuations and hot exhaust gas flows.
