70% of the energy you put in your cars Reciprocating Piston Engine is wasted. The Wankel engine is not much different if not worse; Jet engines are 50% efficient if I am not mistaken.
The two major inhibitors of efficiency for internal combustion engines are.
A – The Mechanical Conversion Mechanism efficiency.
Examples if which
Jet engine.
Reciprocating piston +connecting rod + Crank shaft.
Wankel Eccentric Rotary.
B –Second problem IS the Pressure port problem.
There is one type of engine , “DR.Paul” engine that HAS reversed the efficiency number to 80% thermal efficiency by addressing and solving both problems.
And is producing 900 horse power out of one liter displacement, see the page calle 80% thermally effecient.
While Another type of engine the “Circular engines” only addresses the problem of mechanical conversion.
1-Both engine families increase mechanical CONVERTING efficiency to 100%,
2-Reduce emissions to a fraction “Circular engines”, and to ZERO emersions “DR.Paul engine.”
3-reduce oil demand world wide by 75% see Hekal ,
4-have a higher power to weight ratio, (only Circular. and relatively DR.Paul engine.)
5-Produce 9 to 10 times more power, both engines types (“DR.Paul engine” one liter displacement engine IS producing 900 HP see page (80% thermally efficiency)
6-reach RPMs of 15 to 20 thousand RPMs, only Circular.
7-Simplicity to manufacture and Maintain,
8-low if no Vibration, use normal cheap alloys since this engine runs cooler .
9-have a high compression ratio of up to 30:1 , hence Hydrogen and diesel version would be extremely powerful and possible.
