The Hüttlin Spherical Engine

   
     
Even during the developmental phases of the Hüttlin swivel piston engine, Herbert Hüttlin already wanted to develop a diesel-capable drive principle, as the trend in the automobile industry was moving increasingly in this direction.

Therefore during the design and build of the current prototypes, optimizations were carried out with this objective in mind. New ideas were born, which then led to further patent applica-tions.

However, Herbert Hüttlin was still not satisfied with the results.

The non-reversible physical facts and realizations of the kinematics of the "Hüttlin swivel pis-ton engine" only permit a maximum theoretical compression ratio of 10:1 (The measured val-ues were much lower in practice).

An increase of the resultant compression values could only be achieved by connecting a suit-able pressure booster facility (supercharger, compressor), which, however, would contradict the intended simplicity of the system.

Herein also lie the main motives behind the intensive and continuing development work of Herbert Hüttlin that finally led to the concept of the "Hüttlin Spherical Engine".

The "Hüttlin swivel piston engine" was not designed as a diesel engine. For Hüttlin, optimizing the engine in this direction did not seem feasible in principle due to the flat combustion cham-bers and the complex gasket system.

Hüttlin asked himself the question again and again, whether three-dimensionality might pro-vide the answer for balanced, kinematic action, whereby the moving masses could even be supported by two central axes. If this was a success, he thought, then he would achieve not only dimensionally symmetrical movement, but also the effect of all centrifugal forces would be countered. The counterbalancing, the non-efficiency of centrifugal forces would then automatically prevent any incidence of centrifugal friction and drag co-efficient.

Hüttlin also dreamt of creating kinematic interaction between moving engine parts. As a by-product of form and function, so to speak, this interaction would then create additional pre-compression chambers alongside the 4 otto-typical working volumes, providing the relevant intake chamber with a corresponding pre-pressure.

If this was a success, then the need to build pressure booster systems of any kind, such as air compressors, turbo loaders etc. could be eliminated. If these pressurized chambers could then also carry out the functions of internal motor cooling, a further step along the path of technological progress would be made.

To summarize, the Hüttlin spherical engine could turn the following dreams into reality:
1. Creation and maintenance of symmetrical dimensions over the entire speed range.
2. Reduction of centrifugal forces by centrally positioning the mobile masses at two sepa-rate spherical axes, 90° from each other.
3. Creation of pre-compression chambers to increase the load air pressure of the air intake chamber.
4. Cooling of all internal engine surfaces exposed to heat using fresh air.
5. Generation of high compression necessary for the burning of diesel and bio-fuels.
6. Further simplification of the system: Small spheres have a low capacity, large spheres have a high capacity.
   
7. Even the so-called multiple arrangement of Hüttlin spherical engines are possible (in-line, opposed-cylinder, radial or vee engines).
