Abstract

The energy of one or more gas jets (2) is directly converted to drive force (R) by one or more curved and non-rotating surfaces (1). The energy of the exhaust gas of the internal combustion engine is used to produce the drive force in that it flows at high speed over one or more of the curved surfaces and acts on them with a lower static pressure than appertains on the opposite side. The total pressure difference, related to the projection of opposite surfaces, produces the useful drive force. For flow technique purposes the curved surfaces are highly polished. The curved surfaces have longitudinal grooves in the gas jet direction. The surfaces are held elastically, in order to level out exhaust gas pressure peaks and pressure impulses.

Description

The task is to provide an opportunity find to the residual energy of the exhaust gases (exhaust gases) Internal combustion engines much easier and more effective in Convert driving force. As is known, at Today's internal combustion engines generate over 30% of the energy that caused by the combustion of the fuel, rule pretty exhausted. A very common furniture nowadays Opportunity to use this (rest) energy are the Turbocharger.

Turbochargers use the (rest) of energy by making one Drive the impeller compressor, the air or Mixture in the cylinder comes under pressure and thereby higher specific performance, based on displacement, he can be aimed. There is also the so-called Compound engines, some or all of which Force the turbine wheel via mechanical reduction gear driven - possibly with the help of a fluid coupling - as pure net power on the main motor shaft or the like can be used. When trying with compound motors became a higher efficiency or a lower achieved lower fuel consumption; in practice, however proved the mechanical problems with sub settlement gears, axles etc. costs as very cumbersome.

This is where the process begins. The goal Settlement consists in the residual energy of the exhaust gases (Exhaust gases) with no moving parts directly in useful convert driving force. Because the recoil effect  at lower powers and speeds is not particularly suitable, is furthermore from the Assumed the possibility of (static and kinetic) Energy of the gas jet using fixed, d. H. Not rotating curved surfaces created by the Pressure difference on opposite sides in useful convert driving force.

As is known, it is more atmospheric Air pressure approx. 1 bar. On a body that is not in Is movement, he exercises from all sides on the whole Area even pressure, with the resultant is zero. Through air movement (e.g. sailing ships) or Movement of a certain body shape in the air (e.g. Wing of an airplane or propeller) different pressure on the opposite one Pages are generated, with a driving force (drive or buoyancy) arises. The disadvantage in both cases is that you have to rely on air wind or movement is, although larger areas are required or the body has a higher speed in the air must achieve.

This is where the process (the engine) comes in. Laminar gas jets flow out of one or more nozzles over a curved surface of a body at a higher speed. Due to the speed or higher dynamic pressure, a lower static pressure (according to Bernoulli, Euller and the Navier-Stokes equations) acts on this surface, which is referred to here as negative pressure, while on the opposite side a normal (e.g. atmospheric) or higher static pressure acts, the resultant acting in the direction of the negative pressure ( Fig. 1).

The method (the engine) is particularly suitable to the considerable residual energy of the exhaust gases when burning  engines - especially vehicle engines - directly convert into driving power, with none at all additional moving parts (such as turbine wheels, Reduction gears etc.) are required. Here could be part of a very large turbine rads or a kind of turbine wheel deployment with one or more wings, but their movement doesn’t- like a turbine wheel - circular, but is linear (directed straight ahead).

The process (the engine) can be used both as a main drive instead of other drive means (such as when driving on land testify the drive wheels, in watercraft the Water screw, in aircraft propellers etc.) as also act as an additional auxiliary drive to the Reduce fuel consumption (as it were an "active exhaust").

The optimization or fuel reduction potential for vehicles, this is very high. The production an average pressure difference of only 0.009 bar a total area of 0.333 sqm would result Force of 297 N. The performance in one driving tool speed of 30 m / s (108 k / h) would 8991 W. or 8.99 kw (P = F × V). With a speci The consumption of approx. 230 g / kwh is 2.07 kg and at 0.75 density (e.g. petrol) 2.75 liters per 108 km or 2.55 l / 100 km. With a double pressure difference (0.018 bar) it would be 5.1 l / 100 km.

For strong acceleration or deceleration purposes (i.e. for braking purposes) or even as an "emergency brake" gas generators can also be used, such as this is the case with airbags today.

Further features result from the remaining claims Chen and the following description of not  Examples to be understood as restrictive. These will be like referring to the drawing explained as follows:
