Abstract

In order to produce a piston for an internal combustion engine as well as such an internal combustion engine with a piston according to the invention, which achieves an increase in performance with little economic outlay and enables refined control, the present invention proposes a piston for an internal combustion engine which is characterized in that it has a second piston movable relative to the first piston.

Description

The The present invention relates to an internal combustion engine and a Piston for an internal combustion engine.

in the Range of internal combustion engines there is extensive state of the art Technology and combustion engines for any kind of fuel, Gasolines, diesel, bio-oils, Gas and the like are sufficient known.

One or more pistons are with a connecting rod to a crankshaft hinged and guided in a cylinder. In the cylinder is a Introduced air / fuel mixture and depending ignited by the piston position. The longitudinal movement the piston is over the connecting rod to the crankshaft converted into a rotary motion.

Other Motor types such as Wankel engines, aircraft engines or piston engines The like use pistons rotating in a room.

The Power of combustion engines depends on different Dimensioning parameters and performance increases are through Exhaust treatment, optimization of air / fuel mixtures as well as Optimizations in the exhaust system, the combustion process, the control and the like.

Of the present invention is based on the object, a piston for one Combustion engine and such an internal combustion engine with a piston according to the invention to propose, which with little economic effort an increase in performance achieved and a refined control allows.

to technical solution This task is a piston for an internal combustion engine with the features of claim 1 proposed. An internal combustion engine with a piston according to the invention results from the features of claim 2. Further advantages and features are characterized in the subclaims.

According to the invention is intended to lead into the piston another piston. By This measure Is it possible, additionally to the movement of the main piston and the opposite of the smaller To move the piston. This results in an improved use in the Frame of energy conversion by the explosion of an air / fuel mixture.

tries and calculations have shown that performance increases to about 40% can result. A preferably realized power increase range provides additionally 25% compared a conventional known piston.

One provided with a piston according to the invention Internal combustion engine offers either the advantage that it clearly smaller and lighter can be built without loss of power in purchase have to be taken or he can provide a performance increase with the same size become.

Furthermore There are additional possibilities the fine control, for example, have a very favorable effect on consumption can.

With The invention proposes a novel piston which with little economic effort a significant performance increase without volume change across from conventional piston causes and above offers an improved control option.

Further Advantages and features of the invention will become apparent from the following Description based on the figures. Showing:

1 a perspective schematic representation of an embodiment of the invention.

A piston drive element 1 according to the embodiment shown comprises a piston 2 , The longitudinal movement in a cylinder, not shown, on a crankshaft 3 is transmitted in a conventional manner. For this purpose, the piston 2 with a connecting rod 4 along a hinge axis 5 connected.

In the embodiment shown is in the piston 2 a cylinder area 6 formed, in which another piston 7 running. This piston in turn is also on the connecting rod 8th with the crankshaft 3 connected.

The described embodiment is for explanation only and is not limiting.
