Description

Beschreibung mit Patentansprüchen. Sperrung der Benzinzufuhr während der Schiebephase bei Vergasermotoren, gekennzeichnet durch einen drehzahlabhängigen, elektronischen Schalter, in Verbindung mit einem parallel geschalteten, mechanischen Mikroschalter,. der mit dem Gasgestänge verbunden ist, über die serienmässig eingebauten Leerlaufdüsen beim VW 1500 - 1600. Der Grundgedanke meiner Erfindung ist die Abschaltung der bereits im VW 1500 - 1600 serienmässig eingebauten elektromagnetischen Leerlaufdüsen während der Schiebephase des Motors. ( Die elektromagnetischen Leerlaufdüsen sind nur eingebaut, um beim heissen Motor nach Abstellen der Zündung ein Nachdieseln zu verhindern.) Unter Schiebephase verstehe ich den Zustand nach Zurück-nehmen des Gaspedals während der Fahrt, wenn also der Wagen den Motor antreibt.Description with claims. Blocking of the fuel supply during the shift phase in carburettor engines, characterized by a speed-dependent, electronic switch, in connection with a mechanical microswitch connected in parallel. which is connected to the throttle linkage, via the standard built-in idle jets on the VW 1500 - 1600. The basic idea of my invention is to switch off the electromagnetic idle jets built in as standard in the VW 1500 - 1600 during the engine's shift phase. (The electromagnetic idle nozzles are installed to prevent Dieseling at the hot engine by turning off the ignition.) Trundle Phase I understand the state after rewind take the accelerator pedal while driving, so if the car drives the motor.

Durch eine einfache elektronische--Schaltung in Verbindung mit einem parallel geschalteten, mechanischen Schalter (Mikroschalter), der mit dem Gasgestänge verbunden ist, habe ich das Problem gelöst. Der drehzahlabhängige, elektronische Schalter arbeitet folgendermassen: die sehr komplexen Impulse der Zündspule werden von der Zenerdiode ZZ zu Rechteckimpulsen umgeformt. Ihre Amplitude ist dann gleich der Zenerspannung. Der Kondensator 01 bildet zusammen mit den beiden Pumpdioden D2, .D3 eine Integrierschaltung und gibt bei jedem Impuls eine definierte Ladungsmenge auf die Speicherkapazität C1. Gleichzeitig wird dieser Kondensator von R2 entladen. Je nach Impulsfrequenz = Motordrehzahl stellt sich ein Gleichgewichtszustand ein. Im Leerlauf des Motors ist der Transistor T1 des Triggers gesperrt, Transistor T2 offen und das Relais Rel. angezogen. Dadurch werden die Leerlaufdüsen geöffnet. Der parallel zu den Relaiskontakten liegende Mikroschalter ist offen. Sobald man Gas gibt, schliesst der Mikroschalter und öffnet die elektromagnetischen IreerlaufdUsen unabhängig von der Motordrehzahl. Hat der Wagen nun z.B. eine Geschwindigkeit von 80 km/h erreicht, und man nimmt das Gaspedal ganz zurück, dann wird die negative Ladung an 01 so groß, daß der Trigger umkippt und die leerlaufdijsen abgeschaltet werden. Der Wagen läuft dann ohne Benzinzufuhr weiter. Der Einschaltpunkt kann an den Regelwiderständen R1 und R2 beliebig eingestellt werden, z.B. im vierten-Gang bei 60 km/h, im dritten Gang bei 40 km/h und im zweiten Gang bei 25 km/h. Der Heissleiter H macht die Schaltung thermisch stabil. 02 verhindert ein Flattern des Relais bei niedrigen Drehzahlen. Ich habe diese Schaltung in meinem Wagen VW 1500 S seit einem halben Jahr eingebaut und erprobt. Sie funk-. tioniert einwandfrei. Die Vorzizge: 1. Benzinersparnis, besonders im Stadtverkehr und im Gebirge, weil der Motor in der Schiebephase kein Benzin mehr braucht.By means of a simple electronic circuit in conjunction with a mechanical switch (microswitch) connected in parallel with the throttle linkage connected, I solved the problem. The speed-dependent, electronic The switch works as follows: the very complex impulses of the ignition coil become transformed by the Zener diode ZZ into square pulses. Their amplitude is then the same the Zener tension. The capacitor 01 forms together with the two pump diodes D2, .D3 an integrating circuit and emits a defined amount of charge with each pulse to the storage capacity C1. At the same time this capacitor is discharged by R2. Depending on the pulse frequency = engine speed, a state of equilibrium is established. When the engine is idling, transistor T1 of the trigger is blocked, transistor T2 open and the relay Rel. picked up. This will open the idle nozzles. The microswitch parallel to the relay contacts is open. As soon as one Accelerates, the microswitch closes and opens the electromagnetic nozzles regardless of the engine speed. If the car now has a speed of, for example 80 km / h reached, and you take the gas pedal all the way back, then the negative Charge on 01 so large that the trigger tips over and the idle jets are switched off will. The car then continues to run without fuel. The switch-on point can be on the variable resistors R1 and R2 can be set as desired, e.g. in fourth gear at 60 km / h, in third gear at 40 km / h and in second gear at 25 km / h. The hot conductor H makes the circuit thermally stable. 02 prevents the relay from fluttering at low speeds. I have this circuit in my VW car 1500 S installed and tested for six months. You radio. works perfectly. The advantages: 1. Fuel savings, especially in city traffic and in the mountains, because the engine no longer needs petrol in the shift phase.

z. Bessere Bremswirkung des Motors beim Zurücknehmen des Gaspedals. Schonung der Bremsen,.besonders bei Talfahrten im Gebirge.z. Better braking effect of the engine when releasing the accelerator pedal. Protection of the brakes, especially when driving downhill in the mountains.

3. Auspuffgase werden ungiftiger.3. Exhaust gases become less toxic.

In der Schiebephase ist das-Gemisch besonders fett, weil die Drosselklappen des Vergasers geschlossen sind und die Verbrennung durch Sauerstoff-°.angel unvollkommen ist.In the shift phase, the mixture is particularly rich because the throttle valves of the carburetor are closed and combustion is imperfect due to a lack of oxygen is.

4. Das Ö1 des Motors bleibt länger frisch.4. The engine oil stays fresh longer.

Durch die unvollkommene Verbrennung des Gasgemisches in der herkömmlichen Schiebephase kondensiert Benzin an den _ Zylinderwänden und verdünnt das Öl. Besonders hervorzuheben ist, daß. beim Starten des kalten Motors, wenn die Startautomatik d.en.Motor mit erhöhter Drehzahl laufen lässt, keine Schwierigkeiten entstehen, weil die Kurvenscheibe der Startautomatik das Gasgestänge so weit anhebt, dass der Mikroschalter dauernd eingeschaltet ist und somit auch die elektromagnetischen Leerlaufdiesen. Hat die Startautomatik das Gasgestänge vollständig freigegeben und läuft der Motor mit normalen Leerlaufdrehzahlen, dann wird meine Schaltung voll wirksam. (Schalterstellungen in der Zeichnung wie bei normalen Leerlaufdrehzahlen - Zeerlaufdizsen geöffnet -.)Due to the imperfect combustion of the gas mixture in the conventional shift phase, gasoline condenses on the cylinder walls and dilutes the oil. It is particularly noteworthy that. When starting the cold engine, if the automatic starter allows the engine to run at increased speed, no difficulties arise because the cam of the automatic starter lifts the throttle linkage so far that the microswitch is continuously switched on and thus also the electromagnetic idling. Once the automatic starter has fully released the throttle linkage and the engine is running at normal idling speeds, my gearshift is fully effective. (Switch positions in the drawing as for normal idling speeds - Zeerlaufdizsen open -.)
