Combustion control system adding a liquid, exhaust gases, and PCV gases

A combustion control system for adding a fluid to the air-fuel mixture of the induction system of an internal combustion engine in response to engine need for the added fluid to improve the combustion of the fuel in the engine, said system comprising

• variable impedance flow control means for producing an impedance to flow through the control means, which impedance varies in a non-linear relationship to the pressure differential across the control means and an acceleration of flow through the control means, said flow control means having inlet means and an outlet,
• outlet means connecting the outlet of the variable impedance flow control means to the induction system of the engine, and
• input means for supplying a liquid and engine exhaust gas to the inlet means of the variable impedance flow control means,
• the variable impedance flow control means, outlet means, and input means providing a fluidic computer which combines the inputs of exhaust gas from the manifold near one cylinder, PCV outlet gases, liquid from the reservoir, and atmospheric air in proper amounts and proportions with no moving parts.
