Abstract

In the procedure for reducing the toxic emissions from a car, the car is fitted with two time switches and a temperature controller with advanced time, connected to the internal wiring. The first switch is mounted on a part of the car which does not move when the car is stationary and the second switch is by the gear lever at the 1st-gear position. The temperature controller is on a heat-carrying part of the car and joined to both switches and the ignition switch. When the car is stationary, the first switch switches off the engine 30 seconds after normal operating temperature is reached and it is re-started by the second switch when first gear is engaged.

Description

Einleitungintroduction

Ein derartiges Verfahren ist von großem prak­ tischem Interesse, denn es ermöglicht, die Schadstoffwerte durch die Zwangsabschaltung des betriebswarmen Verbrennungs­ motors zu verringern. Neben den positiven Auswirkungen auf die Umwelt, kann die Kraftstoff-Ersparnis beim Stop-and-go beträchtlich sein.Such a method is very practical tical interest because it enables the pollutant values due to the forced shutdown of the warm combustion to reduce motors. In addition to the positive effects on the Environment, fuel savings can be made at stop-and-go be considerable.

Stand der TechnikState of the art

Es sind zwar Verfahren bekannt, stehende Landfahrzeuge durch das Fahrpedal aus- bzw. anzuschalten diese haben sich aber in der Praxis nicht durchsetzen können. Die Mängel liegen in der Art der Handhabung und der Auslösung des Vorganges auch beim noch nicht betriebswarmen Motor.Methods are known, standing Turn off or on land vehicles by the accelerator pedal have not been able to prevail in practice. The shortcomings lie in the way it is handled and triggered of the process even with the engine not yet at operating temperature.

Aufgabetask

Die Erfindung hat sich die Aufgabe gesetzt, diese Nachteile zu vermeiden und auch bei älteren Fahrzeugen durch Nachrüstung eine Reduzierung des Kraftstoffverbrauches sowie der Schadstoffwerte im Abgas zu erreichen.The invention has set itself the task of this Avoid disadvantages and also with older vehicles Retrofitting a reduction in fuel consumption as well to achieve the pollutant values in the exhaust gas.

Lösungsolution

Das Verfahren nach der Erfindung beruht darauf, daß an einem, bei Stillstand des Fahrzeuges sich nicht mehr bewe­ genden Teilen, (Antriebe, Räder, Tachometer) ein Kontaktgeber befestigt wird.The method according to the invention is based on the fact that on one, when the vehicle is stationary, no longer move parts, (drives, wheels, speedometer) a contactor is attached.

Der mit dem Bordnetz des Fahrzeuges verbundene Kontaktgeber leitet den Impuls an den Temperaturregler. Dieser an einem wärmeführenden Teil (Motor, Abgasanlage, Katalysator, Kühl­ system, bzw. als Kombinationsgerät mit Kühlmitteltemperatur­ anzeiger) angebrachte Temperaturregler ist mit dem Zündanlaß­ schalter verbunden und schaltet den Verbrennungsmotor nach erreichen der Betriebstemperatur sowie einer Vorlaufzeit von 30 Sekunden automatisch ab.The contactor connected to the vehicle's electrical system passes the impulse to the temperature controller. This one heat-conducting part (engine, exhaust system, catalytic converter, cooling system, or as a combination device with coolant temperature indicator) attached temperature controller is with the ignition switch connected and switches the internal combustion engine reach the operating temperature and a lead time of 30 seconds automatically.

Die Vorlaufzeit wurde gewählt:The lead time was chosen:

  • - Damit der Fahrzeuglenker sich auf die Situation einstellt.- So that the driver adjusts to the situation.
  • - Rangieren und parken nicht zu behindern.- Do not hinder maneuvering and parking.
  • - Nach längerer hoher Motorbelastung einen Wärmestau zu ver­ meiden. - To build up heat after a long period of high engine load avoid.  
  • - Schadstoffausstoß und Energieverbrauch sind nach dieser Zeit bei Neustart des Motors niedriger.- Pollutant emissions and energy consumption are after this time lower when the engine is restarted.

Der am Schalthebel (Schaltgabel) - 1. Gang angebrachte zweite Kontaktgeber ist über den Temperaturregler mit dem Zündanlaß­ schalter verbunden. Mit dem Einlegen des 1. Gang bei noch aus­ reichender Betriebstemperatur springt der Motor wieder an und das Fahrzeug setzt sich gleichzeitig in Bewegung.The second gear attached to the shift lever (shift fork) - 1st gear The contactor is via the temperature controller with the ignition starter switch connected. By engaging 1st gear at still off sufficient operating temperature, the engine starts again and the vehicle starts moving at the same time.

Die Anlaß-Wiederholsperre im Lenkanlaßschloß verhindert, daß der Anlasser bei laufendem Motor einspurt und dadurch beschädigt werden kann.The anti-repeat lock in the steering starter lock prevents the starter meshes while the engine is running and damaged as a result can be.

Bei Fahrzeugen die älter als fünf Jahre sind und nicht über den erforderlichen Stand der Technik verfügen, wird der Vorgang mechanisch durch einen Knopf am Schalthebel ausgelöst.For vehicles that are older than five years and not over the process will have the required state of the art mechanically triggered by a button on the gear lever.

Der Knopf ist am Kopf des Schalthebels integriert und abhängig von dessen Ausführung. (Knüppel-, Revolver-, Lenkradschaltung) Kontaktgeber und Vorlaufzeit sind dafür nicht erforderlich, da die Auslösung des Vorganges mechanisch erfolgt.The button is integrated and dependent on the head of the gear lever of its execution. (Stick, revolver, steering wheel control) Contactor and lead time are not necessary for this, because the process is triggered mechanically.

Der Knopf am Schalthebel ist über den Temperaturregler mit dem Zündanlaßschalter verbunden.The button on the gear lever is over the temperature controller with the Ignition switch connected.

Mit dem Eindrücken des Knopfes der durch eine Feder wieder in seine Ausgangsstellung zurückgeht wird der Verbrennungsmotor bei erreichter Betriebstemperatur aus- bzw. eingeschalten.By pushing the button back in by a spring the internal combustion engine will return to its initial position switch on or off when the operating temperature is reached.

Die einzustellende Schwankungsbreite des Temperaturreglers richtet sich nach Fahrzeugart, -typ, -modell, Einsatzbedin­ gungen und Ausstattungsgrad (Dieselmotor, Vergasermotor, Ein­ spritzmotor mit und ohne geregeltem Katalysator) und kann nicht generell bestimmt werden.The fluctuation range of the temperature controller to be set depends on vehicle type, type, model, application conditions conditions and equipment level (diesel engine, carburettor engine, on injection engine with and without regulated catalyst) and can cannot be generally determined.

Wird die vorgegebene Schwankungsbreite des Temperaturreglers nach längerer Stehzeit des Fahrzeuges unterschritten, erfolgt der Start in gewohnter weise.The specified fluctuation range of the temperature controller after the vehicle has been idle for a longer period of time the start in the usual way.

Vom Hersteller festgelegte Funktionen des Lenkanlaß-Schloß bleiben voll erhalten und sind von dem Verfahren unabhängig funktionstüchtig.Functions of the steering starter lock specified by the manufacturer remain fully intact and are independent of the procedure working.
