Title: (EN) Natural gas vehicle tank life sensor and control
Abstract: front page image
(EN)

A natural gas vehicle fuel system includes a composite pressure vessel for storing natural gas. The vessel includes an internal storage space accessible via a port opening. A solenoid valve is operatively coupled to the port opening for selectively connecting the storage space to a natural gas supply for filling or to a vehicle engine, in use. A sensor is integrally mounted with the vessel for sensing a select event of vessel operation indicative of the vessel exceeding a useful life expectancy. A control is operatively associated with the sensor for controlling the valve operation, the control preventing further operation of the solenoid valve after the vessel has exceeded the useful life expectancy.
