The dual injection airlift pump has a hollow tubular body through which the liquid being pumped passes upward from the lower intake end to the upper outlet end. Air or other gas is injected into the liquid in the pump body, the less dense gas adding buoyancy to the liquid and entraining the liquid to rise toward the outlet end. The dual injection airlift …Web

Both methods of injection accomplish the ultimate goal of vaporization, but in vastly different ways. "Port injection operates at a much lower pressure of the two. It's injected into the runner at basically atmospheric pressure, unless the engine has forced induction," says Fenske of the 40-45 psi of fuel pressure standard fuel injection ...Web

So VW in all their wisdom designed a new engine to replace the old, thus the EA888 was born with dual injectors! One set would be mounted in the port (where they would clean the valves off during normal driving) and another set inside the combustion chamber (thus the name direct injection) for that extra efficient power when needed.Web
