DE19700869A1 - Double internal combustion engine - Google Patents

Abstract

Combustion takes place on both sides of the piston. The piston rod passes through the cylinder head in such a way that expansion of the combustion gases can be used almost without losses. There is a device to deflect the to-and-fro movement of the piston rod, before it is converted into a rotary movement.

Description

The invention relates to an internal combustion engine according to the preamble of Claim 1.

In order to achieve a high degree of efficiency in internal combustion engines, one should keep the frictional resistance and the weight as low as possible.

Internal combustion engines (petrol and diesel engines) are generally known. As well is known the principle of the steam engine, by the internal combustion engine was pushed out further and further.

The disadvantage of the internal combustion engine compared to the steam engine is that that the piston does work only when moving in one direction. The Steam engine, on the other hand, needs one in addition to the fuel one Water supply.

The current energy discussion makes it necessary to use more economical engines develop. This is achieved by building lighter and lower-friction engines. It is necessary that they are easy to maintain and therefore economical stay.

In order to meet these requirements, the advantages of the double engine were of steam engine and internal combustion engine combined. The above were mentioned disadvantages of conventional thermal energy machines avoided. Of the Double engine is an internal combustion engine, on both sides of the piston combustion takes place.

From the principle outlined above it follows that in the case of the double engine with the same Dimensions of the cubic capacity almost double compared to a conventional engine  is so big.

The associated weight reduction does not result in energy savings stationary engines.

The lower mass of the moving parts and the reduced friction have an effect continue to have a positive impact on energy consumption.

Explanation of how it works

In the double engine, the fuel-air mixture is burned on both sides of the piston. Depending on the design, it can run on all fuels with which you can also operate other internal combustion engines.

In a petrol engine, the connecting rod rotatably mounted on the piston transmits the Force directly on the crankshaft. In the case of the double engine, the second must also be used Combustion chamber on the other side of the piston to be sealed. This will also closed this side with a cylinder head. Through this second The cylinder head becomes the piston rod rigidly connected to the piston passed through. Like a steam engine, the force is generated by the piston rod Transfer to the connecting rod to the crankshaft via the crosshead. The piston must be flat on both sides.

With the double engine, two out of four work steps can be used:

To avoid the geometry of the double engine compared to the current engines change, it is advisable to close the piston rod with a deflection device Mistake.

Claims (3)

1. Piston engine for performing work, characterized in that combustion takes place on both sides of a piston in a cylinder. 2. Cylinder head for closing the combustion chamber 2 (see drawing), characterized in that a piston rod can be passed through so that the expansion of the combustion gases can (almost) be used without loss. 3. device for deflecting the movement of the piston rod, characterized in that the back and forth movement is deflected, before it is converted into a rotary motion by the crankshaft.
