Description
wälzpumpe 23 vorgesehen, dessen Wasserkreislauf über die Leitung 21 in die Rohrleitung 17 einmündet und gleichfalls über den Abgaswärmetauscher 18 geführt wird und den Wärmetauscher 19 des Verdampfers 4 durchströmt. Durch eine von der Leitung 20 abgehende Abzweigleitung 24 ist die Verbindung zur Umwälzpumpe 23 hergestellt und somit der Wasserkreislauf 21 geschlossen. circulating pump 23 is provided, the water circuit over the line 21 opens into the pipe 17 and is also passed through the exhaust gas heat exchanger 18 is and the heat exchanger 19 of the evaporator 4 flows through. By an outgoing line 20 Branch line 24 is the connection to the circulation pump 23 and thus the water circuit 21 is closed.
Für den Kaltstart der Brennkraftmaschine 11 ist ein Behälter 25 mit Startkraftstoff, wie z. B. Methan (Eidgas), Propan u a. vorgesehen, welcher bei vorherrschenden normalen Druck- und Temperaturverhältnissen gasförmig ist Dieser Kraftstoffbehälter 25 ist über ein zwischengeschaltetes Reduzier- und Schaltventil 26 in einer Leitung 27 unmittelbar mit dem oberen Teil des Verdampfers 4 verbunden. Die kalte Brennkraftmaschine 11 kann durch Steuerung eines strömungsseitig am Ausgang des Verdampfers 4 angeordneten Thermostaten 29 die Leitung 27 öffnen, so daß der Startkraftstoff dem oberen Teil des Verdampfers 4 zugeführt und die Brennkraftmaschine sofort, also ohne Vorwärmzeit, gestartet werden kann.For the cold start of the internal combustion engine 11 is a container 25 with starting fuel, such as. B. Methane (Eidgas), Propane et al. provided, which under prevailing normal pressure and temperature conditions is gaseous This fuel tank 25 is via an interposed reducing and switching valve 26 in a line 27 is connected directly to the upper part of the evaporator 4. The cold internal combustion engine 11 can be controlled on the flow side on Output of the evaporator 4 arranged thermostat 29 open the line 27, so that the starting fuel the upper part of the evaporator 4 is supplied and the internal combustion engine is started immediately, that is, without a preheating time can be.

Claims (1)
Durch die Erfindung wird erreicht, daß einerseits der Verdampfer für den Betriebskraftstoff und andererseits der Motor rasch aufgeheizt werden. Denn Verdampfer und Motor werden in der Startphase der Brennkraftmaschine mit kurzgeschlossenen Kühlwasserkreisläufen betrieben, wobei dem Kreislauf für den Verdampfer Wärme aus Motorabgaser zugeführt und im Kühlwasserkreislauf möglichst wenig Wärme abgeführt wird.The object is achieved according to the invention by the characterizing features in claim 1.
The invention achieves that, on the one hand, the evaporator for the operating fuel and, on the other hand, the engine are heated up quickly. This is because the evaporator and motor are operated with short-circuited cooling water circuits in the starting phase of the internal combustion engine, with heat from the engine exhaust gas being supplied to the circuit for the evaporator and as little heat as possible being dissipated in the cooling water circuit.
