A method of detecting a malfunctioning high-pressure gas tank 4 comprised within a vehicle 1, which method comprises retrieving first and second system gas pressure values (p1, p2, figure 3) at first and second points of time (t1, t2, figure 3); retrieving data related to temperature and pressure of gas supplied to an engine 12 between the first and second points of time; determining an expected gas pressure drop within the system 2 based on the data; determining an actual system gas pressure drop by comparing the first and second pressure values determining a pressure drop delta by comparing the actual pressure drop and the expected pressure drop and triggering an indication if the delta exceeds a predetermined threshold thereby providing a warning of occurrence of at least one malfunctioning tank 4. Said warning may comprise an acoustical alert, or a visual warning such as a lamp or warning message 18. The gas in said system may optionally be hydrogen, methane, or compressed natural gas (CNG). A solenoid valve 6 may be disposed in the system to enable or restrict the flow of gas to the engine 12. |
