ABSTRACT:
A valve body and injector nozzle support that can be utilized with a multi-port internal combustion engine cylinder head so that the induction passage can be tuned to provide a relatively small effective area to generate turbulence at low speeds and low loads and provide a substantially unrestricted passage under high speed high load conditions. A number of embodiments of such arrangements are disclosed and each is effective in improving the engine torque throughout the entire engine speed and load ranges.
