V-Twin Compound Engine

The idea consists in modifying a "90º V-Twin" engine for a compounded operation, with one of the cylinders (Low Pressure Cylinders) receiving the exhaust gases from the other cylinder (High Pressure Cylinders) through a common central manifold. With this design, when a HP cylinder exhaust opens its corresponding LP cylinder is at 90º from TDC, maximizing efficiency at collecting the energy of the high pressure wave generated at the beginning of the exhaust stroke and reducing the pressure and temperature of the exhaust gases.

I already have submitted the idea to some engine manufacturers, but I have not obtained interest yet, that´s why I am trying to find other designers interested in developing further the idea to increase its attractive to potential investors. The idea would be to use existing V engines to produce low cost-high efficiency versions of their existing engines with low development and investment costs.
