Hello! Here is in some pages the presentation of ET-MOTOR—first rotary modular revolving cylinder engine with tangential combustion. This concept was born in my spirit more than one decade ago, by imagining that a thermal engine could function differently than with the antiquated "crank connecting-rod" system. This simple idea gave birth to ET-MOTOR.
After manufacturing a wooden model which reproduced "mechanically" the new system, I set up a couple of plans to develop the prototype, which was made by a small French workshop. The precision of the parts is 1/50th. That is to say that it corresponds to mechanics of 100 years ago. Hence quite far away from the great precision of today’s engines.
However, as one can read on this site, ET-MOTOR runs very well. The ignition was developed by a specialist of electronics named Daniel CARALLI who rules a small tuning workshop in la Seyne sur Mer, close to TOULON - Var Department - Southern France. He is henceforth a team partner.
Most difficult was the development of vaporization. Because, when still believing in the adjustment of the traditional piston engine which functions with a mixture of gas and air in proportion of 1 per 15—that is to say 1 gram of gas for 15 grams of air—, ET-MOTEUR never functioned with this tuning. And the mixture only exploded first after an incredible impoverishment of the internal combustion engine.
Today the intake is done by two pipes. One 12MM diameter air pipe and a propane pipe with its 4/10 MMS jet indeed . The ratio of these two sections corresponds to 1/900. It is very far from the 1/15 ratio of the piston engine.
And if this realization is applied in the future on engines built according to the ET-MOTOR concept, with a higher degree of accuracy, we should expect a phenomenal and incredible fuel-saving capacity!
Moreover as an engineer a mechanic or a motor mechanic, you cannot miss the opportunities that this new revolving thermal engine can bring. Besides these advantages are described in more details on opposite page. As incredible it may appear incredible, it is reality.
ET-MOTOR can be developed in any country. For this purpose, exclusive or not-exclusive licences including the participation of the team and their make-of, are ready to be delt. Contact us!

40 to 50 times fuel-saving capacity!?!?
Fore sure, this means saving energy, diminishing pollution and increasing range. ET-MOTOR turns experimentally with a 5 bars pressure out of a mixture of propane and air, with a proportion of 1/900! and not of 1/15 as in a traditional internal combustion engine!!
No vibrations
as there is any alternative movement from parts
little heating, little lubrication
because push rods contact occurs only on one 30° sector, per one 360° turn, that is to say 1/12th by turn.
Light and very easy to build
Few moving components: 2 wheels by module and their push rods.
evolutionary:
possibility of multiplying modules
For what uses is it intented?
According to ET-MOTOR team, it would be perfect to do run economically and with a great autonomy, new economic power generating units...... What is already well. But it can be surely exploited for many other uses....
