Definitions
- the invention relates to an internal combustion engine according to the preamble of patent claim 1.
- Such an internal combustion piston machine is known, for example, from US 3200797.
- the GB 469,883 has a design that combines conventional connecting rods and crankshafts in one Rotary cylinder used.
- Another GB 126,109 has a construction that has a circumferential Cylinder used as the drive element.
- GB 114,667 describes a conventional radial engine in one revolving cylinder.
- Another GB describes a similar construction with conventional cranks 565,652.
- GB 1734 from 1915 presents a construction with pistons controlled by cranks, the force is taken from the rotating cylinder.
- the FR 935520 shows a construction using Crankshaft controlled pistons in a revolving cylinder when using valve controls.
- the FR 1.262.597 shows a construction in which the rotating cylinder is used as a control element and the pistons oscillate back and forth.
- the US 2,273,025 shows the construction of a conventional radial engine. the revolving cylinder is used only as a control.
- CH 418725 and US 3,200,797 show a construction by means of a crankshaft controlled pistons, the speed of the rotating cylinder to the drive shaft in a ratio runs from 1: 2. High pressure ratios are due to high side forces on these engines Do not use the cylinder wall as the rotating cylinder is not supported without force.
- Fig. 1 shows a longitudinal section through the construction.
- Fig. 2 shows a cross section
- Fig. 3- 6 different working phases of the engine in cross section in a schematic representation.
- a cylindrical housing 9 the ends of which each have a sealing cap 91, 92 are closed, is, in a known manner, rotatable about the central axis of the housing 9 and at the latter Cylinder bore through sealing rings 101, 102 (Fig.1) and straight sealing strips 103, 104 (Fig.2) on the housing 9 sealed cylinder carrier 10 stored in the bearings 11 and 12.
- cylinder carrier 10 In the cylinder carrier 10 is located in known way, a perpendicular to the housing center axis and diametrically extending, cylindrical bore 105 - the cylinder of the engine - in which on a cranked, straight line, to Drive center 13 offset housing center on the connecting rod arm rigidly connected to the drive shaft 13 131, in the connecting rod pin 14 rotatably mounted piston 15 is guided.
- the piston stroke is the measure of the twice the distance of the drive shaft from the housing axis.
- the cylinder carrier and drive axle rotate in a ratio of 1: 1 and with one revolution of the cylinder carrier 10 and the drive shaft 13 two Working strokes carried out.
- openings 93, 94 arranged for the injection nozzles 16, 17.
- the housing has, in a known manner, two further openings 18, 19 (Fig.2), from which the opening 18 as an outlet for the combustion gases the work space and the opening 19 serves as an inlet for the fresh air supplied by a blower.
- cylinder carrier 10 and piston 15 have cavities for cooling 151.152.
- the housing 9 has two bores 95, 96, which means that an oil pump is used Cooling oil is pumped through cylinder carrier 10 and piston 15. The plain bearings are covered by pressure oil lubricated. 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 101, 102 provided (Fig. 1) and intersecting in the longitudinal direction with the sealing rings 101, 102 Sealing strips 103, 104 (Fig. 2).
- the piston 15 has reached the top dead center, with which simultaneously in the compression spaces 161, 162 (FIG. 1) between the piston end wall 153 and the Housing 9 (Fig. 1) the highest possible compression of the air has occurred.
- fuel is injected into the compression space, causes the expansion force Stroke of the piston 15 in the direction of the arrow drawn in the piston and a rotation counter to that Clockwise, since the drive shaft 13 was turned in this direction by the starter.
- the working space 172 between the piston end wall 154 of the piston 15 and the housing 9 takes place the outlet of the burned gases through the slot 18th escape.
- the piston Due to the lack of the crankshaft bearing in the piston, as described in CH 418725, the piston can largely hollow, which ensures perfect cooling by oil or fuel itself, can be done, even with the much lower spec. Heat of the oil or fuel Water. In this way it can be guaranteed that the sliding surface temperatures do not reach 250 ° C exceed.
