Dual Pressure Intake Engine

Using the Double Acting 'Uniport Valve'

(Patent #5,782,215)

Increasing thermal efficiency by ~1 % and hp by ~8 %

Importance of Uniport Valve
For the
Dual Pressure Intake Engine

A dual intake engine is possible without using the Uniport Valve. But the extra port area it provides (~39% more intake area) is what allows an engine to keep its volumetric efficiency while increasing the thermal efficiency.
