DE102006012814A1 - Internal combustion engine e.g. diesel internal combustion engine, has pairs of upper and lower rotatable disks, which come into contact with each other periodically during operation such that compression and working cycles are induced - Google Patents

Abstract

The engine has four cylinders (5) with pistons (6) and piston rods (7), and fuel pipelines, which are provided with rotatable seals and plunger pumps. The cylinders are attached between two pairs of upper and lower rotatable disks (2, 3) in a circular manner. The disks are separated from each other and come into contact with each other periodically during the operation of the engine, in such way that compression and working cycles are induced in the engine.

Description

Concerns piston engines.

Known and widespread are conventional ones Internal combustion engines. With them are the thrust crank and the charge control mechanism the most important elements.

The basic disadvantages of these engines are in a large mass, a low efficiency of the crank mechanism and a complicated construction of the charge control mechanism.

Known are engines with different mechanisms of power conversion from Piston, which performs a rectilinear motion, in the rotational movement of Wave.

In CA 2330591 A1, the motion conversion takes place by means of the energy the combustion products as well as additional chambers.

In CA 2186548 C will use the motion transformation with additional ensured small chambers with pistons. The cyclic sequence of operations of the piston is through realized a kinematic belt transmission.

In DE 4228639 A1 the motion conversion is achieved by moving, opposed cylinders. Such a solution allows a compact construction. However, with power units, the use of such a model involves problems of effective cylinder cooling and other operational difficulties.

aim The present invention is the development of an internal combustion engine without crank and without gas distributor mechanism.

This goal is achieved by the construction of a fundamentally new engine. 1 shows the construction scheme of such a four-cylinder engine. By design, the number of cylinders can be arbitrarily large.

On a frame 1 are two upper ones 2 and two lower ones 3 rotatable discs installed. These are kinetic with the cylinders 5 and the piston sticks 7 connected, which are arranged in a circle. The upper and lower discs are connected to the cylinders and at the same time act as rotors of the air turbines.

The axes of the upper and lower disc pair are offset from each other to a height e, and all four axes lie on one level. There are two pins on each cylinder and piston rod 4 which are offset with their axes to the height e and are mounted on the bearings of the upper and lower discs.

A such kinematic connection allows a permanent spatial orientation of Cylinder axes and piston rods independently of rotation angle of the discs.

The piston rods and cylinders are always facing each other in a circular motion and are in line. The synchronous rotation of the discs and the transmission of the torque from the lower discs 3 on the output shaft 14 done using gears 13 , The pistons 6 are separated from the piston rods and are located in the cylinders. During engine operation, the pistons and piston rods only periodically contact each other, causing the clocks of compression and operation.

The fuel gets over the fuel line 10 and a rotatable seal plunger pumps 9 fed, which are mounted on each cylinder.

The rotatable upper discs 2 act as an air turbine. Through it is fed via channels in the pin necessary for the operation of the engine and the cooling of the cylinder air. The fuel combustion products are discharged by means of the lower disks, which also act as a turbine 3 ,

The Operation of the engine is as follows: During the operation of the acts Piston on the piston rod, bringing him to a linear Shift. This shift is inseparable from a rotation connected to the discs and the output shaft. This way will the reciprocation of the piston in a directed rotational movement converted to the Abtrebswelle.

A complete work cycle consists of three cycles: compression, operation and cylinder drainage. The compression stroke begins with the contact of the piston rod with the piston. At the end of the compression stroke, the ram works 11 the piston rod at a certain, precisely predetermined position of the piston on the plunger pump and thus causes the introduction of the fuel into the combustion chamber.

This is followed by the operation, at the end of which the piston first opens the outflow and then the scavenging slots of the cylinder. The combustion products are in the negative pressure range of the turbines of the lower discs 3 ejected, where they mix with the outside air and then removed from the engine.

To Completion of the operation is followed by the third clock, the cylinder drainage. The piston loses contact with its piston rod and is located while this time after execution of a Circular motion in relative calm. At that moment, the compressed Turbine over the channels in the cones and the rinsing slots in the cylinders the air blowing and cooling the cylinders until Piston and piston rod come into contact again.

After this the first cylinder is processed, the piston of the second occurs Cylinder in contact with his piston rod and thereby passes the Duty cycle of the second, then the third and all subsequent Cylinder on. The lead out the piston from the dead points is made by the rotating mass the discs, which act as flywheels. Therefore must the rotational movement of the output shaft to be very stable.
