METHOD OF MANUFACTURING AND CONTROLLING A BUTTERFLY VALVE FOR AN INTERNAL COMBUSTION ENGINE |
摘要 |
A method of manufacturing and controlling a butterfly valve for an internal combustion engine; the manufacturing and control method includes the steps of: establishing a maximum gaseous flow rate value which may flow through the feeding pipe when the butterfly plate is in the closing position; determining a conventional closing position at which the gaseous flow rate which flows through the feeding pipe is essentially equal to the maximum gaseous flow rate value; driving an actuator device so as not to normally pass the conventional closing position; and dimensioning the position of a catch element, so that when a rotational shaft abuts against the catch element the gaseous flow rate which flows through the feeding pipe is essentially lower than the maximum gaseous flow rate value.
