DE2850760A1 - Rotary piston IC engine - has outer ends of pistons and valves controlled by elliptical track inside combustion chamber - Google Patents

Abstract

The rotary piston engine (10) has an oval shaped chamber. It has four pistons carried inside a rotating circular block with the outer ends of the pistons guided by a sleeve following the oval contour of the inside of the chamber. The pistons operate in holes in the block, with their axes at right angles to each other. As the block rotates, the pistons reciprocate against the oval chamber. The combustion gases circulate through channels bored through the block, controlled by valves at the inner ends of the pistons, also operated by the oval track.

Title:

Support disc reciprocating internal combustion engine

.Field of use:

The invention relates to a support disks reciprocating internal combustion engine, and is intended as a prime mover for land, sea and air vehicles as well as for stationary devices.

Purpose:

The pressure energy released during the "combustion of a compressed, combustible mixture acts on a piston in such a way that it generates a torque via a mechanism on a shaft which can be used to drive vehicles and equipment.

Suand der It is known that in today's internal combustion engines, the pressure energy released during combustion is diverted from the linear movement determined by the cylinder and piston into a rotary movement with the help of a crank mechanism.

Technology:

Due to the type of construction, the effective lever - cranking of the crankshaft - at the beginning of the work cycle, when the connecting rod and the cranking almost form a line, is very small. The greatest effective lever length is only achieved when the crank and connecting rod are at an angle of 90 degrees to each other. The force therefore acts exactly in the direction of rotation. At this point, however, the piston has already covered almost half of its working stroke and the expansion pressure is above the The piston has sunk by about 80 per cent.

According to the law of mechanics, torque = ■ force times lever arm Achieving a large torque the greatest force act on the longest lever. A state that cannot be reached with the crank drive Here is becoming more expensive and increasingly scarce energy being used incorrectly and dadurcri wasted.

Task of
Invention:-

The invention is based on the object of a To create internal combustion engine, in which dia effective lever arms at the beginning of the work cycle30 already have an optimal length, and the eel ' the expansion pressure acting on the piston can be used significantly better.

The economy as well as the liter output and the mass-performance ratio must be egg-cutting be improved.

Solution of the
Task:

The object is achieved according to the invention in such a way that within a fixed containment body with an inner guide rail of oval contour, a centrally mounted support plate with cylindrical bores - which in the direction of rotation the support disk should be arranged - the reciprocating piston leads gas-tight. When the support disc rotates around its own axis, each reciprocating piston becomes - with movable bearing points suspended and supported in the oval guide rail and inevitably following this twice from its top to bottom dead center emotional.

Achievable As the expansion force of the cylinder compressing advantages: th and ignited mixture from the time of greatest pressure generation on via the reciprocating piston on a long lever - here formed by the support disc - directly in the direction of rotation of the shaft works, meet the greatest strength and long leverage here This results in:

The combustion chamber volume can be used to achieve the same performance compared to the conventional crank drive can be significantly reduced.

The reduction in the volume of the combustion chamber saves fuel.

With the long lever arm, a large torque is achieved, which is already a good pulling power can be expected.

The mass-performance ratio as well as the Litsr power are improved without increasing the compression.

Carrying disc-reciprocating internal combustion engine, in which within a stationary surrounding body with an inner guide rail of oval contour, a centrally mounted carrying disc with cylindrical bores - which should be arranged in the direction of rotation of the carrying disc - guides the reciprocating piston in a gas-tight manner. When the support disc rotates around its own axis, each piston becomes - with movable bearing points in the oval guide rail suspended and supported - inevitably moved twice from its bottom to top dead center. The gas exchange in the cylinder bores, which are sealed gas-tight by the reciprocating pistons, is regulated with valves. which above the cylindrical bores in the support disc are arranged, and are operated by control tracks in the bearing sides of the enclosure body.
