Lavine ABSTRACT: A rotary piston engine is provided with a chamber in which is a glow plug: a pair of passages, controlled by a rotary valve, communicate that chamber with the piston chamber or hollow, the passages entering the piston chamber or hollow substantially at the median plane of rotation of the rotary piston and at circumferentially spaced points.

l HIIHIIWIIIHH GLOW IGNITION DEVICE FOR ROTARY PISTON ENGINES Hitherto there were used in rotary piston engines conventional spark ignition systems with high-tension coils and makebrake devices.
The drawback of such devices when applied to rotary piston engines is rapid wear of the spark plugs and the difficulty of obtaining a correct spark at high speeds, as usually in engines of such type a single spark plug operates all chambers and sparking must occur at a frequency equal to the number of chambers, i.e. several times higher than that occuring in conventional engines.
Therefore, a primary object of this invention is to provide an effective ignition system for trochoidal rotary piston engines, ensuring the correct ignition of the mixture at high engine speeds by means of a simple and inexpensive device.
This object has been achieved by providing a glow-type ignition device constructed so that the operating space of the engine is connected through one or more channels in the engine body with a rotary gate that uncovers or screens a glowing glow plug and enables igniting of the mixture by the glow plug. The glow plug is heated electrically from a low-tension installation. The rotary gate is drivenfrom the engine shaft through suitable gearing.
The ignition device according to the invention does not have the disadvantages of the spark plug-type ignition as the life of the glow plug does not depend on the frequency of igniting, since the intensity of igniting of the glow plug is constant and independent of the engine speed.
The ignition control is etfected mechanically, forcedly.
The gate is a simple fail-safe element. Providing of several channels connecting the glow plug with the combustion space permits the achieving of ignition at several points of the combustion chamber simultaneously. Further, the location of the channels inlets, being approximately in the median plane of rotation of the rotary piston, and circumferentially spaced, causes the flow of the combustible mixture in these channels at the moment they are connected by the rotary valve gear and there is thereby effected scavenging of the remaining combustion gases in the proximity of the glow plug.
IN THE DRAWINGS HO. 1 is a cross-sectional view taken along the axis of a rotary piston engine provided with the glow ignition apparatus of the present invention.
HO. 2 is a cross section taken on the line A--A of FIG. 1.
The device shown in F105. 1 and 2 comprises two channels I and 2 in the engine body 3 and conducted to the rotary gate valve 4 driven from the engine shaft by suitable gearing. In the said gate valve controlling the channels 1 and 2 to the electrode 6 of the glow plug 7 a cutout 5 is provided connecting in a first position thereof channels 1 and 2 with the electrode 6 of the glow plug 7: glow plug 7 is mounted in a chamber in the engine body 3. In a second position, the connection is closed. The channels 1 and 2, as shown in FIG. 1, enter the engine hollow 8, defining the combustion chamber, substantially at v the median plane of rotation of the rotary piston as shown in FIG. 2; these points are circumferentially spaced, thereby enabling scavenging of changer .in which is located the electrode 6.
Operation of the ignition device according to this invention enables the rotary gate valve 4 to connect through the cutout 5 the channels 1 and 2 with the glowing electrode of the glow plug 7 at the predetermined moment for ignition. At the said ignition moment a part of the compressed combustible mixture rushes into the chamber and is ignited by the electrode of the glow plug. The combustible mixture also scavenges the chamber as a result of the pressure difference at both sides of the contraction of the trochoid. An increase is pressure follows the ignition and part of the burning mixture is blown through the channels 1 and 2 into the operating chamber of the engine and causes ignition of the mixture compressed therein.

l. A rotary piston internal combustion engine of the trochoidal type comprising a hollow body and a rotary piston therein,
