Patent ID: 7093589

Claim:
An air induction system for inducing airflow into the intake of an internal combustion engine having a turbocharger, said system comprising: an air filter operable to clean air drawn from an air intake; and a clean air channel in fluid communication with an outlet of said air filter so that an airflow is formed therein, said clean air channel having one end directly coupled or connected to an outlet of said air filter and the other end of said clean air channel being directly coupled or connected to an inlet of said turbocharger, said clean air channel having a structure located in front of an inlet to said turbocharger operable to restore pressure head and subsequently increase the velocity of said airflow, wherein the structure comprises means for both restoring pressure head after said airflow has traveled at least a portion of said clean air channel and redirecting said airflow at least approximately 90 degrees from a direction of said airflow exiting said outlet of said air filter to a direction of said airflow entering said inlet of said; and a bell-mouth transition positioned between said structure and said inlet of the turbocharger, said bell-mouth transition having a bell-mouth outlet connected to said inlet of the turbocharger and defining a cross-sectional area at said bell-mouth outlet that is less than said cross-sectional area of said structure.
