THROTTLE LOSS RECOVERY AND SUPERCHARGING SYSTEM FOR INTERNAL COMBUSTION ENGINES

摘要

A system and method of creating sub-atmospheric and super-atmospheric pressure in an intake manifold (20) of an internal combustion engine (10) that has cylinders (14) within which fuel combusts with air that has entered the cylinders via the intake manifold. A positive displacement airflow control device (26) is disposed upstream of the intake manifold. Sub-atmospheric pressure in the intake manifold is created by applying negative external torque to a shaft (28) of the positive displacement airflow control device and super-atmospheric pressure is created by applying positive external torque to the shaft (28).
