Definitions
- the invention relates to an internal combustion engine according to the preamble of patent claim 1.
- a power piston engine is known, for example, from US 3200797
- Such Brer-cd-raft-piston machines offer the possibility to achieve previously unachieved efficiencies by using very high pressure ratios, above 1:25, and relaxing the exhaust gases down to 1 bar while simultaneously charging the cylinders.
- GB 469,883 has a construction that uses conventional connecting rods and crankshafts in a rotating cylinder.
- Another GB 126,109 shows a construction that uses a rotating cylinder as the drive element.
- GB 114,667 describes a conventional radial engine in a rotating cylinder.
- Another GB 565,652 describes a similar construction with conventional cranks.
- GB 1734 from 1915 presents a construction with pistons controlled by cranks, whereby the force is drawn from the rotating cylinder.
- the FR 935.520 shows a design using pistons controlled by a crankshaft in a rotating cylinder when using valve controls.
- the FR 1262597 pointing t a construction in which the rotating cylinder is used as control member and the piston oscillating back and forth.
- the US 2,273,025 shows the Konstruküon a herk ö mmlichen S t ernmotors, wherein the circumferential cylinder is used only as a control.
- High pressure ratios are mch t apply in these engines due to high side forces on the cylinder wall, since the rotary cylinder is not mounted force-free. Forces decreases in the rotary cylinder are inadmissible f o r high pressure conditions, because the action of lateral forces have been eliminated on the cylinder walls by such constructions and high pressure ratios can also be applied CHT ö k.
- the übngen, proposed with crankshafts constructions ban from the above-ext similar agreements referred to reasons of bending and jamming. Conventional valve controls prohibit a high degree of delivery.
- ERSATZBLAH (RULE 26) sealed by fins, rotates, and the housing is also calculated in a known manner between 180 ° and 270 ° from the injection nozzle in the direction of rotation of the cylinder carrier, is provided with two flushing holes, one of which is connected to a blower, and the other through which relaxed exhaust gases are discharged.
- Cylinder carrier and drive shaft are mounted on both sides independently of each other in the housing. The construction is explained in more detail using drawings. 1 shows a longitudinal section through the construction. 2 shows a cross section, and the
- Fig. 3 - 6 different working phases of the engine in cross section in a schematic representation.
- a cylindrical housing 9 the ends of which are each closed by a closure cap 91, 92, is, in a known manner, rotatable about the central axis of the housing 9 and at its cylinder bore by sealing rings 101, 102 (Fig.l) and straight sealing strips 103, 104 (FIG. 2) on the housing 9 sealed cylinder carrier 10 in the bearings 11 and 12.
- cylinder carrier 10 there is, in a known manner, a cylindrical bore 105 - the cylinder of the motor - which runs at right angles to the center axis of the housing and diametrically extending, in the drive shaft 13 which is rigidly connected to the drive shaft 13 on an cranked, straight line, offset to the center of the housing Connecting rod arm 131, piston 15 rotatably mounted in connecting rod pin 14.
- the piston stroke is the measure of twice the distance of the drive shaft from the housing axis. Cylinder carrier and drive axis rotate in a ratio of 1: 1 and with one revolution of the cylinder carrier 10 and the drive axis 13, two working strokes are carried out.
- openings 93, 94 for the injection nozzles 16, 17 are arranged in a known manner.
- the housing has, in a known manner, two further openings 18, 19 (Fig.2), of which the opening 18 as an outlet for Combustion gases from the work space and the opening 19 serves as an inlet for the fresh air supplied by a fan.
- Fig.2 two further openings 18, 19
- the cylinder carrier 10 and the piston 15 have cavities for cooling 151, 152.
- the housing 9 has two bores 95, 96, whereby cooling oil is pumped through the cylinder carrier 10 and piston 15 by means of an oil pump.
- the plain bearings are lubricated with pressure oil. All of the cooling and lubrication can also be done by the fuel itself if the engine is operated with heavy oil or vegetable oils.
- the cylindrical outer wall of the cylinder carrier 10 is with sealing rings
- Conventional piston rings 155, 156 are provided to seal the piston in the cylinder bore.
- the mode of operation of the engine according to the invention is described in more detail below, essentially using FIGS. 3-6. It is emphasized that the engine should be operated as an internal combustion engine with injection.
- the flushing slots 18, 19 are arranged offset by about 230 ° to the top dead center of the piston 15, whereby the compression path is shortened in a known manner compared to the expansion path, so that the compression volume is smaller than the expansion volume. This allows complete relaxation of the exhaust gases. With one revolution of the drive shaft 13 and thus also of the cylinder carrier 40, two work cycles are generated.
- the piston Due to the lack of the crankshaft bearing in the piston, as described in CH 418725, the piston can be made largely hollow, so that proper cooling by oil or the fuel itself can take place, even with the much lower spec. Heat of the oil or fuel over water. In this way it can be guaranteed that the sliding surface temperatures do not exceed 250 ° C.
- Flushing slots can be overloaded to an air pressure of the desired height depending on the arrangement of the flushing slots.
