Abstract

The device has a tube section (1) and a hollow body (2), where a annular gap is provided between the section and the body. The gap is large in size in order to let necessary amount of fuel to flow thorough the gap, where low fuel volume is present between the section and the body and the fuel is heated by an e-heater. The device is wired with a connector (3) for a cigarette lighter and is thermally insulated and packed.

Description

Die Umrüstung von Dieselmotoren auf Bio-Kraftstoffe ist aufwendig und kosteninten siv. Ein zusätzlicher Kraftstoffbehälter für übliche Mineral-Kraftstoffe ist erforderlich, um den Motor zu starten und die Warmlaufphase zu ermöglichen. Nach ca. 5 bis 6 Minuten ist die Betriebstemperatur des Motors erreicht und es kann nun, manuell oder auch automatich, auf Bio-Kraftstoff umgeschaltet werden. Ein Wärmetauscher ist noch erforderlich um den Bio-Kraftstoff auf die erforderliche Temperatur vorzuwärmen.The conversion from diesel engines to biofuels is costly and expensive intensive. An additional one Fuel tank for common mineral fuels is required to start the engine and the warm-up phase to enable. After approx. 5 to 6 minutes, the operating temperature of the engine is reached and it can now, manually or automatically, on bio-fuel be switched. A heat exchanger is still required to bio-fuel to the required Preheat temperature.

Im Folgenden ist ein Gerät beschrieben, bei welchem Zusatztank, Wärmetauscher und kostenaufwendige Installation entfallen.in the Following is a device described in which additional tank, heat exchanger and costly Installation omitted.

An einem Rohrstück aus Kupfer (1) sind an beiden offenen Seiten jeweils eine Schlauchtülle (3) zum Anschluss an die Kraftstoffleitung zwischen Kraftstofffilter und Einspritzpumpe angebracht. Im Inneren des Rohrstücks befindet sich ein Hohlkörper (2) aus dünnem Blech, dessen Aussendurchmesser ca. 1,5 mm kleiner ist als der Innendurchmesser des Rohrstücks. Zwischen Hohlkörper und Rohrstück entsteht nun ein kleiner Ringspalt. Einer grossen Wärmeübertragungs-Fläche steht ein minimales Kraftstoff-Volumen gegenüber, das in wenigen Sekunden durch eine E-Heizung (4) auf die erforderliche Temperatur erhitzt werden kann.On a piece of copper pipe ( 1 ) are on both open sides each a hose nozzle ( 3 ) for connection to the fuel line between the fuel filter and the injection pump. Inside the pipe section is a hollow body ( 2 ) made of thin sheet metal whose outer diameter is about 1.5 mm smaller than the inner diameter of the pipe section. Between hollow body and pipe piece now creates a small annular gap. A large heat transfer surface is confronted with a minimal volume of fuel, which can be replaced in seconds by an electric heater ( 4 ) can be heated to the required temperature.

Die E-Heizung wird mittels Bi-Metallelement (5) reguliert. Mit einer Justierschraube (6) kann die gewünschte Temperatur eingestellt werden.The electric heating is by means of bi-metal element ( 5 ). With an adjusting screw ( 6 ) the desired temperature can be set.

Das Ganze ist wärmeisoliert verpackt.The Whole is thermally insulated packed up.

Das Gerät ist mit einem Stecker zum Anschluss an den „Zigarettenanzünder" und einer Kontrollleuchte in diesem fest fest verdrahtet und kann so jederzeit, falls erwünscht, ausser Betrieb gesetzt werden.The Device is with a plug for connection to the "cigarette lighter" and a warning light Hardwired in this case and can be used at any time, if desired, except Operation are set.
