INTERNAL-COMBUSTION ENGINE.

Application filed August 20, 1917.

To all whom it may concern:

Be it known that I, Ennnsr R. OLSEN, a citizen of the United States, residing at the city and county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines.

The objects of this invention are:

First, to provide in an internal combos tion engine an improved cylinder structure.

Second, to provide an internal combustion engine having an internal rotary cylinder sleeve member constituting a valve and which may be removed and inserted from the outer end of the cylinder without removing the piston.

bird, to provide an engine of the rotary valve sleeve type which is simple in structure, economical to manufacture and efficient in operation.

Fourth, to provide an internal combustion engine of the type described in which the crank shaft makes a plurality of revolutions to a single revolution of the sleeve valve.

Fifth, to provide an internal combustion engine of the type described, with means for admitting steam to the cylinders thereof during each intake stroke of the pistons.

Sixth, to provide novel means utilizing the heat of the exhaust for supplying steam to said cylinders.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of m invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompan ing drawing forming a part of this speci cation, in which:

Fig. XIV is a partial end elevation of the base of my improved engine showing the connections between the crank shaft and the worm shaft for actuating the sleeve valves, a portion of the gearing housing being broken away.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, my improved engine comprises the base 1, which may have any suitable contour and is provided with a manhole having the closure 2 therefor.

The cylinders 3 are, in the embodiment illustrated, formed integral with the upper portion of the base and are surrounded by a water jacket 4, which is also formed integral therewith. The cylinders 3 are formed in pairs connected by the webs 5.

The internal cylinder sleeves or valve members 6 are rotatably mounted within the cylinders o. 'lhecylinders and valve menibcrs are provided with coacting shoulders. as indicated at 7 in Fig. IV, whereby the valve members are rotatably supported in the cylinders. The lower ends of the valve members project from the lower ends of the cylinders and are provided with gear teeth 8, which are ei'igaged by the threads of the worms 9 on the worm shaft 10. The worms for each pair of cylinders are pitched in opposite directions, as indicated in Figs. IX and X, so as to drive the sleeve valves of each pair of cylinders in opposite directions.

The worm shaft 10 is provided with a pinion 11 which meshes with an idler 12 driven by a gear 13 on the crank shaft 14, so that the cylinder sleeve members are driven in synchronism with the movements of the crank shaft.

The pistons 15 reciprocate in the sleeve members 6 and are connected by means of pit-men 16 with the crank shaft. Each of the members (i is provided with three inlet ports 17. which lie in the same plane and are uniformly spaced. Each cylinder is provided with a pair of inlet ports 18 and 18 respectively. The inlet ports 18 and 18' are connected by means of passages, formed integral with the cylinders and water jacket. with the intake manifold 19, the intake ports 18 being connected with the manifold by means of a comn'ion passage, as shown in Fig. II. The inlet ports 18 and 13' are spaced apart an angular distance equal to the spacing of the ports 17 in the sleeve valves, whereby two of the ports 17 may register with the ports 18 and 18 simultaneously.

Each cylinder 3 is also provided with a pair of exhaust ports 20, which are spaced apart an angular distance equal to the angu lar spacing of the ports 17 of the valve member.

Ihe ratio of the gearing between the crank shaft 14 and valve members 6 is such that the former makes six revolutions to a single revolution of the latter. This means that the engine will perform three complete cycles during each revolution of the valve member. The intake ports 18 and 18 are, therefore, spaced from the adjacent port 20 substantially thirty degrees.

I also provide means for admittin steam to the cylinder during the latter part of each intake stroke. This means comprises the ports 21. which are so located that they register with one of the sleeve valve ports 17 during the latter part of each intake stroke. These ports are connected by means of passages, cast integral with the water jacket, with the steam manifold 22.

For supplying steam to the man fold 22 I provide a steam boiler 23, which is separate from, but supported upon, the exhaust manifold. the bottom wall of the boiler being conformed to the contour of the exhaust manifold in order to insure ellicient heat transmission.

In order to provide for more etlicicnt heating of the water in the boiler 23 I provide a circulation tube 24-. one end of which is connected with the lower side of the boiler and the other end of which is connected to the up ier side of the boiler. an intermediate portion of the circulation tube passing through the exhaust manifold, as shown in dotted lines in Fig. VI, and in dotted lines in Fig. I.

To provide for a greater evaporative power, the surface of that portion of the circulation tube which passes through the exhaust manifold may be increased in any desirable manner. A steam dome 25 com municates with the boiler 23 and receives the steam therefrom. A pipe 26 leads from the steam dome 25 to the steam manifold 22, a ortion of the pipe passing through the cylinder head 27. as shown in Figs. HI and VI.

The cylinder heads are formed of a single hollow integral body member having the depressions 28 therein for receiving the spark plugs. Depending annular flanges 25) at the lower side of the cylinder head coact with corresponding grooves in the top of the cylinder walls to form a tight joint between the cylinder and the cylinder head. The bottom of the cylinder head is also provided with apertures opening into the water jacket.

The outer peripheries of the sleeve valves are provided with crossed spiral. grooves '30 for receiving lubricating oil under pressure. The oil is supplied through the passage ways 31 and the lubrication manifold 32. The oil is supplied under pressure and there fore works along the spiral grooves 30-.

The lower end of the intake conduit 33 is formed with branches 34 and 35 which lead to the carbureters 36 and 37, respectively. One carbureter is designed for the use of the heavier distillates, such as kerosene, and the other is intended to be used. with the lighter or more volatile distilla'tes. Butterfly valves 38 are mounted in each of the branches 34 and 35 and are operated by means of the cranks 39 and the rods 40 connected thereto.

.It is believed that the operation of my improved engine will be apparent from the above description.

Referring to Fig. II. the valve nieinlyiers. starting with. the left hand cylinder and continuing toward the right. are shown in firing. compression. exhaust and intake positions, respectively. Referring to the right hand cylinder, it will be seen that before the completion of the intake stroke of the piston in this cylinder the valve port 17 will register with the steam port 21, there by admitting steam to the cylinder during the latter part of the intake stroke.

By providing a )lurality of intake and exhaust ports in l e cylinder and vlalve members, the explosive charges are readily drawn into the cylinder and the exhaust gases encounter little resistance to their expulsion. therefrom, and, by providing means for applying a suitable quantity of steam to the cylinder during the intake stroke the vaporization and combustion of the fuel is rendered more efficient and deposition of carbon upon the cylinder walls largely prevented.

By providing the two carbureters and the butterfly valve 38 the more volatile fuels inay'be used for starting the engine, and then. by properly manipulating the butter fly valve 38 the engine may be run upon the heavier fuels.

By providing shoulders upon the sleeve valves which coact with the shoulders 4 of the cylinders, and by cutting the gear teeth 8 in the lower edge of the sleeve valves, I provide means whereby they may be quickly and easily removed through the top of the cylinder without disturbing the pistons and their connections with, the crank shaft.

In the modified embodin'ient of my invention disclosed in Figs. XI to XIV inclusive, I have illustrated a construction in which the crank shaft is designed to make four revolutions to each revolution of the sleeve valve. In order to secure this result I have provided the valve members 6 with oppositely disposed ports 17 which simultaneously register with the inlet ports 18 and 18, or the exhaust ports 20 and 20 twice during each revolution of the valve member. The arrangement of the inlet ports and the exhaust ports in this embodiment of my invention is the same as that in the embodiment previously described, except that the inlet ports are spaced slightly from the exhaust ports. In this modification of my invention the inlet and exhaust manifolds are formed integrally, as in the embodiment first described, and this combined manifold is provided with additional passages 211 which are connected with the steam manifold 22 by means of branched conduits 22", the opposite ends of the steam passages 21 discharging into steam conduits 2.1 that are formed integral with the cylinder casting, and discharge adjacent the intake ports 18, these steam ports being spaced relative to the intake ports 18 in such a manner that they disel-iargc into the cylinders during the latter portions of the intake strokes of the pistons. The steam manifold 22 may receive its steam supply from a steam boiler similar to that described above or from any other suitable source.

The gears 11, 12 l3 and the Worm wheel 8' and worm 9' should be so designed that the sleeve valve (3 will make lour revolutions to each revolution of the crank shaft 1 l.

While I have ilh'lslrated and described two embodiments of my invention, 1 desire it to be understood that my invention is capable of other :ulaplations and modilicw lions falling within the scope of the Ill) pended claims.
