Abstract
A Calibrated Air Intake Tract for Internal Combustion Engine is disclosed. The intake includes a Mass Airflow Sensor section that defines an inner diameter that differs from the diameter of the overall intake air tract piping. The Mass Airflow Sensor length and diameter are precision-tuned in order to provide the best engine performance without the typical “check engine” light being lit due to faulty mass airflow sensor readings. In those vehicles where necessary, an insert of the appropriate size and in the proper location is added to the interior wall of the MAFS section in order to correct final fuel trim level inadequacies.
Claims13
An intake air system for an internal combustion engine, comprising:
- a distal intake pipe portion;
- a MAFS pipe portion adjacent to said distal intake pipe portion;
- an air infusion insert comprising an elongate member located within said MAFS pipe portion;
- and
- a proximal intake pipe portion between said MAPS pipe portion and the internal combustion engine, and external to said internal combustion engine;
- wherein said distal intake pipe portion defines a first inner diameter at its proximal end and said MAFS pipe portion defines a second inner diameter, said second inner diameter being less than said first inner diameter, the diameter of the distal end of said MAPS pipe portion being substantially the same as said first inner diameter.
An air intake system for an internal combustion engine, comprising:
- a distal intake pipe portion defined by an intake air filter at a first end;
- a MAFS pipe portion adjacent to a second end of said distal intake pipe portion, said MAPS pipe portion sized to mate with said second end, said MAFS pipe portion having rigid walls;
- an air infusion insert pipe disposed within said MAPS pipe portion and in longitudinal alignment therewith;
- and
- a proximal intake pipe portion adjacent to an opposing end of said MAFS pipe portion, said proximal intake pipe portion adapted to attach to the internal combustion engine.
