1) A two-stroke fuel-air injection IC engine.

2) An air motor with a built in fuel combustor.

3) A cyclic rocket engine with piston and

    crankshaft as the output.

4) A clean engine with digitally metered

​    fuel and air injections.

Innovations

1) ECE is an external combustion thermal

    engine with no moving parts.

2) Through thermal cycles of free-electrons

    in metal, ECE converts thermal energy

    directly into electricity in high efficiency.

​​Electronic Carnot Engine

1) A rotary engine with Fuel-Air

    injections apply to a modified

    Wankel engine.

​2) A cyclic rocket engine with rotor

    and eccentric shaft as the output.
