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.
Claims7
A method for creating an intake air system for an internal combustion engine, comprising the steps of:
- running the engine;
- testing the exhaust gas composition of the engine during said running;
- replacing the intake air system of the engine with a proposed intake air system defined by a mass airflow sensor diameter;
- rerunning the engine;
- retesting the exhaust gas composition of the engine during said rerunning;
- and
- constructing a replacement intake air system comprising a distal intake pipe section and a mass airflow sensor tract selected from a group of mass airflow sensor tracts and further having an air infusion insert located within said mass airflow sensor tract, said air infusion insert comprising an elongate tubular member, said constructing responsive to said retesting.
