2. Applications in motorization

The numerous advantages and parameterizations offered by the PRBC concept
 demonstrate its particular relevance in all motorized applications...

2.1. Cars

luxurious topless car4x4 / SUV full hybride
hybrid city-car

The following assets of the PRBC concept will be especially interesting in the motorization of a car :


- its variable output power

- its possibilities of variable wedging to manage valves

- its favorable 
kinematics for non conventional combustions like auto-ignition and detonation(HCCI, CAI, ATAC, Diesotto concept...),

All type of car can welcome the PRBC engine, from the city-car to the big 4x4, and these vehicles, thanks to the gains of space offered by the PRBC's compactness, will be able to be equipped with batteries and more powerful electric motors, that is to say to become the FULL Hybrid, propelled by two ways of which one is not dominant as regard to the other.

The ultra-compactness of the PRBC engines lets consider completely new architectures like one motor by axle, and even by wheel (4x4 without transmission therefore less consuming), without talking about all new possible organization of the space allocated to the passengers (and not to the motor...) inside the vehicle, that can be increased practically from 50% to equal measurements of the vehicles


2.2. Motorcycles / "2 wheels"

ScooterTrail motorcyclehypersportive motorcycle

The following assets of the PRBC concept will be especially interesting in the motorization of the "2 wheels" :


- its high volumic power

- the absence of vibration procuring a comfort and a better roadholding

- the torque at low RPM which lead to a good reactivity of the motorcycle at the starting or re-launch

All type of motorcycles can welcome the PRBC engine, from the moped / scooter until the hypersportive while passing by the "road motocycle". Thanks to the gains of space offered by the PRBC's compactness, the tanks / ranging will be able to be a lot bigger. The motorcycles will be also lighter and will be able to equal weight, to take more of passengers and/or luggage and fuel.

The ultra-compactness of the PRBC concept lets consider completely new architectures with one motor by wheel, opening the way thus by "all land" motorcycles with 2 driving wheels (2x2) of which the capacities of ascension will be better, as well as the safety in case of breakdown of one of the motors.


2.3. Light portable tooling

The following assets of the PRBC concept will be especially interesting in the motorization of the light portable tools :

- its big volumic power

- the absence of vibration procuring a comfort to the user and the preservation of his/her muscles and joints.

It can constitute a small revolution for the workers who are victims at short-term of tingles, stiffness because of the vibrations of their tools, and at longer-term, they endure engrave musculo skeletal stroubles.

One will try here to keep an equal power with a smaller motor, therefore lighter, thus relieving the arms and the backbone of the operators.


2.4. Light motorized rolling tools

The following assets of the PRBC concept will be especially interesting in the motorization of the light motorized rolling tools:

- its high volumic power

- the absence of vibration procuring a comfort to the user and the preservation of his/her muscles and joints.

One will try here to multiply the power to equal volume to make the tool more efficient.



2.5. Trucks

middle / heavy transportation trucksuper heavy transportation truck

The following assets of the PRBC concept will be especially interesting in the motorization of the trucks :

- the very strong torque at low RPM allowing an optimal traction of the load


- the abscence of vibration procuring a comfort for the dwellings and the residents


All type of truck can welcome the PRBC engine. A truck of 20 Tons wastes at every braking an energy equivalent to the one of 20 cars achieving the same braking. Thanks to the gains of space offered, the trucks will be able to be equipped with efficient systems of energy recovery when braking ; the gains of consumption are capable to pass the easily 30% on a non higway course .To equal power, the lowering of the mass of the motor, the reduction of /its volume and the kinetic energy recuperation when braking are vital to better extract the Diesel  fuel's energy, especially nowadays where the road transportation, boosted by the globalized economy, develops itself in an exponential way.


2.6. Light and middle aviation

motopropelled airplane private bimotor airplane Hélicopter
motorisable glider ultralight helicopter Ultralight airplane

The following assets of the PRBC concept will be especially interesting in the motorization of the light and middle planes :

- the absence of vibration procuring a better stability to the device, especially for motors bound of the wings

- the PRBC's lightness encouraging the takeoff and limiting the bending of the wings when they must carry them

- the PRBC's power, in particular at high RPM because they are perfectly well balanced.

- the reduced size of the engine, encouraging 
the wing's lift by the combination of :
- a reduction of the turbulences generated by the contounement of the fluid around the motor
- an increase of the wing bearer surface


The PRBC's ultra-compactness  lets consider completely new architectures of airships even :

- with a light central motor but very powerful sending its power:
        -   via driveshafts: the wings, whose rigidity would be assured in part by the structure of the driveshafts,      
            would be equipped thus only with helixes and would maximize their lift while lowering their trail.

        -   via an electric network with the help of a generating electricity station and with electric motors in tip of wing, adjustable.
  
- or the addition of one or several rotors of helicopter to a structure standard of plane

And even the most original projects like of the "double thermal / electric hybrid" AND car / plane ! !

Let's mention the very interesting works of the society Milner http://www.milnermotors.com/aircar.htm

Therefore, the way is opened to airships of vanguard, potentially with vertical takeoffs and landings (VTOL) well more efficient and sure thanks to the multiplication of the motors and to the total independence between the horizontal and vertical propulsions.


2.7. Middle and heavy military contraptions

The following assets of the PRBC concept will be especially interesting in the motorization of the middle / heavy military contraptions

- the particularly aim of vibrations' absence in submarines and in all applications requiring the discretion.

- the lightness of the motor encouraging quick mobilities , notably on heavy armored contraption where 1 second of delay can be fatal

- the high power very useful to propel the chariots of assault, or the cargo airplanes' helixes.


2.8. Vehicles of leisure

2.9. Hydraulic motors



The PRBC concepts can be nourished by pressurized fluid and turn themselves into into perfectly balanced and compact hydraulic or pneumatic motors with high torque at low RPM. To avoid all neutral point during the motion, it is sufficient to join 2 PRBC engine where their the 2 shafts are wedged with a precise angle.

The applications are extremely vast, from the actuating of an excavator's caterpillars until the hydrolelectric powerplants, especially bass, middle and even high fall (to see as small hydraulics)

3. Applications in pump / compressor


The PRBC engines are reversible and under the condition to have a source of rotary mechanical energy ; they turn themselves into extremely compact and perfectly well balanced pumps / compressors, resistant to pressures going until several score of Bar.

It is even possible with a same motor block to have rooms of combustion and other pneumatic rooms of air. By a simple game of floodgates "all or nothing", it is possibleduring the braking to store compressed air in a tank, and during the next acceleration, reinject the compressed air in the pneumatic room to re-launch the vehicle.

Instead of being lost in the brakes as heat, the kinetic energy of braking is recycled thus with an excellent output and a very reasonable clutter. It is a simple and efficient means to decrease considerably the consumption and the pollution, especially in urban environment.
