Abstract

A simple valve system for an IC engine has a single rotating shaft (2) set across the top of each cylinder and provided with shaped recesses which connect the inlet and outlet ducts to the cylinder. The shaft can be made of metal or ceramic and can be driven from the crankshaft or by a servo motor, e.g. stepping motor. The timing can be controlled electronically or mechanically. No other moving parts are required.

Description

Konzept einer Motorensteuerung mit VentilwelleConcept of an engine control with valve shaft

Dieses Konzept beschreibt die Steuerung eines Viertakt-Verbrennungsmotors, Benzin oder Diesel, ohne Ventile herkömmlicher Weise und Bauart, sowie ohne Nockenwelle, mittels einer Ventil-Welle.This concept describes the control a four-stroke internal combustion engine, gasoline or diesel, without valves conventional Way and design, as well as without camshaft, by means of a valve shaft.

Funktion und Arbeitsweise.Function and mode of operation.

– Konzept zur Steuerung eines Viertakt-Motors mittels Ventilwelle, welche die Ein- und Auslasssteuerung und die Verschlussposition während der Verdichtung und der Verbrennungsphase übernimmt. In der Zeichnung dargestellt als Ventilwelle (2), die im Zylinderkopf (1) oberhalb des Zylinderraumes (5) angeordnet ist, in welchem der Kolben sich bewegt.- Concept for controlling a four-stroke engine by means of a valve shaft, which takes over the intake and exhaust control and the closed position during compression and the combustion phase. Shown in the drawing as a valve shaft ( 2 ) in the cylinder head ( 1 ) above the cylinder space ( 5 ) is arranged, in which the piston moves.

– Skizze 1 – kennzeichnet die Stellung der Ventilwelle (2), welche in Position 1.oo Uhr zum Ansaugen des Brenngemisches den Kanal (4) zum Zylinderraum öffnet.- Sketch 1 - indicates the position of the valve shaft ( 2 ), which in position 1 o'clock to suck the fuel mixture up the channel ( 4 ) to the cylinder room.

– Skizze 2 – kennzeichnet die Stellung der Ventilwelle in Position 3.oo Uhr zum Verschließen des Zylinderraums (5), in welchem der Kolben (6) in der Aufwärtsbewegung die Verdichtung des Gasgemisches vornimmt und nach dem Zünden die frei werdende Energie in bekannter Weise auf die Kurbelwelle überträgt.- Sketch 2 - indicates the position of the valve shaft in position 3.00 o'clock to close the cylinder chamber ( 5 ) in which the piston ( 6 ) compresses the gas mixture in the upward movement and transfers the released energy to the crankshaft in a known manner after ignition.

– Skizze 3 – zeigt die Stellung der Ventilwelle (2) in Position 5.oo Uhr, nämlich das Öffnen des Zylinderraums (5) zum Abluftkanal (3) zwecks Ausstoßen der verbrannten Abgase mit dem Kolben (6) – Beiliegende Zeichnungen zeigen die Grundidee und die genauere Funktionsweise.- Sketch 3 - shows the position of the valve shaft ( 2 ) in position 5 o'clock, namely opening the cylinder space ( 5 ) to the exhaust air duct ( 3 ) to eject the burned exhaust gas with the piston ( 6 ) - The enclosed drawings show the basic idea and the more precise functioning.

– Der Antrieb der Ventilwelle kann konventionell über die Kopplung zur Kurbelwelle erfolgen, oder über eine intelligente Steuerung mittels electronisch geregeltem Schrittmotor, um auch die Steuerzeiten einem zu erwartenden variablen Drehzahlbereich anpassen zu können.- The The valve shaft can be driven conventionally via the coupling to the crankshaft done, or about intelligent control using an electronically controlled stepper motor, around the control times of an expected variable speed range to be able to adapt.

Ein und Auslasssteuerung eines Viertakt-Otto oder Dieselmotors ohne Tellerventile, sondern mittels einer angetriebenen Ventilwelle. Bei einem Kolbenmotor wird statt bei herkömmlichen Tellerventilen das zur Verbrennung benötigte Gasgemisch, sowie das Abgas, über eine mit zentralen, oder seitlich angeformten Durchlassöffnungen versehene Ventilwelle zu oder abgeführt. Die Welle besteht aus Metall, oder auch Keramik, ist in dem Zylinder Kopf gelagert und zum Durchlass des Frisch oder Abgases, mit Bohrungen oder seitlichen Ausformungen versehen. der Antrieb kann entweder vom Motor direkt, oder über entsprechende mechanische, bzw, elektronische Steuerungen erfolgen.Intake and exhaust control of a four-stroke Otto or diesel engine without poppet valves, but by means of a driven valve shaft. With a piston engine instead of with conventional poppet valves this becomes Combustion needed Gas mixture, as well as the exhaust gas, about one with central or side openings provided or discharged valve shaft. The wave exists made of metal, or ceramic, is stored in the cylinder head and for the passage of the fresh or exhaust gas, with bores or lateral formations Mistake. the drive can either be directly from the motor or via appropriate mechanical or electronic controls.
