The CLENERGY rotary diesel engine, ready to make the second prototype.

I personally am very much involved both in ultralight/L.S.A. aviation design and prototyping and in internal combustion engines design and prototyping. For my rotary engine I totally eliminated the pistons and went for a 6 cycles (the cycles are 6 also in the 4 strokes and 2 strokes engines, but they overlap, I managed to separate them for better results) rotary burning chamber that spins circular like a "brush less electric" engine (unlike the Wankel engine that "bumps" 3 times in a rotation) eliminating thus the need to convert linear movement into circular movement with gain of power, less parts, less vibrations, no need for valves, thus the valves phasing mechanisms, that makes the engine lighter, and not only, but in theory there is no RPM limit given by the return spring of the valves capacity (in practice there are limits due to air density, mechanics and so on, I limited it to 20.000,00 RPM for safety)
Due to it's conceptual particularity my engineer managed to differentiate the size of the intake and compression sector from the explosion and burning sector, giving the last one a 30% extra room, this leads to a nearly complete burning of the mix, more forced applied to the piston, less heat in the exhaust (about half of it) and also leads to acceptance 0f many different fuels in the design stage (obviously once build for a certain range of fuels, so it remains)
First prototype I made in cast iron was a 100 CC Otto engine on carburetor that weighted without starter and dynamo some 5 Kg (about the size of your both fists together) and although we hoped for 50 HP it gave only 25 HP due to a design error that induces some mechanical drag in the rotary pistons. Now I keep it with a plexiglass wall for didactic purposes.
We now have designed a 1000 CC diesel 40 to 1 compression ratio, (and we eliminated all the errors we found in the first prototype), and we calculated a power output of 200 HP pessimistically. It should probably weight with starter and dynamo and all around 50 Kg.
The beauty of this engine is the simplicity, continuous absorption of air, continuous injection/spark, continuous explosion, runs nearly like a turbine, but with an internal combustion cycle, that leads to turbine like sizes and powers with a piston like consumption and 5% of a "piston like" pollution. The number of components is one quarter than a piston engine, and requires no electronics to manage it, and the way is conceived allows even for 25 CC engines to use small car diesel injectors and fuel pump. Looking to partner with people to finalize prototyping and bring it to the markets

The sustainable economic downsizing

The thing to do that is proposed here is an old new way of living that can be expressed in the sentence "Let the machines work, while we enjoy life"

To do that we basically need to rethink as a whole and in detail the human living dominated by the absurd imperative of money accumulation, merchandise production end purchase against money, tax and profit existence.


But us, with our small possibilities, how can we take such an approach when who governs us nowadays is sabotaging such options systematically when is not straight forward forbidding them, simply because such form of society is not using banking credits nor creating taxes that for the time being are the vital blood of the economy of destruction that we practice?

Any opinion?
