70% of the energy (heat) you put in your cars Reciprocating Piston Engine is wasted as the engine throws it out into ambient air (atmosphere).
The Wankel engine is not much different if not worse; Jet engines are 50% efficient if I am not mistaken.

There are two inhibitors of efficiency or limiting factors for this deficiency of internal combustion.

The mechanical conversion mechanism factor or problem……

and …

the pressure (vessel) port factor or problem

In this weblog i will try to explain the solution for both problems.

A – The Mechanical Conversion Mechanism efficiency.

The Conversion mechanism is the Means or method or mechanical utility or device used to convert Pressure/Heat into useful work – torque

Examples if which
Jet engine.
Reciprocating piston +connecting rod + Crank shaft.
Wankel Eccentric Rotary.

B –The Pressure port (vessel) problem. What is the meant by Pressure port.

In order to make use of the pressure we have from combustion we need a chamber (vessel) to contain the pressure of burned gasses, in order for pressure to do its work on the converting part (piston or wankel rotor or blade in jet engine) .

For example in the Reciprocating Piston engine the pressure would ACT on the piston crown and push it and move it to twist teh crank.

The solution for both problems is discussed in this blog separately .

1-Both solution or engine families increase mechanical CONVERTING efficiency.
Cicular engines + Opposing pistons engine two stroke
2-Both solutions Reduce emissions to a fraction for “Circular engines”, and to ZERO emesions “DR.Paul” opposing piston engine .

In the Opposing pistons engine they had so much excess POWER that they cooled the exhaust till they eliminated heat signature . so no one can send an IR tracking missile up its exhaust pips.

3-reduce oil demand world wide by 75% (see Hekal ).

4-have a higher power to weight ratio. both engine types.

5-Theoretically produce from 4 to 9 to 10 times more power.
still no final real life figures just mathematical predictions depending on preliminary designs, While a real life figure for the “DR.Paul engine” a one liter displacement engine IS producing 900 HP see page (80% thermally efficiency)

6-reach very high RPMs . (theoretical in C.E engines).

7-Simplicity to manufacture and Maintain, both.

8-low if no Vibration, symmetry in design so auto balanced .

9-have a high compression ratio of up to 30:1 , hence Hydrogen and diesel version would
be extremely powerful and possible.

10-use normal cheap alloys since this engine runs cooler.
