摘要
In a gas-supply system for supplying a generic engine of a vehicle type, comprising electronic control means for controlling delivery devices associated to various engines, said electronic control means are programmed for processing the data regarding the low-pressure part of the system according to a predetermined algorithm, at predefined instants, in order to enable timely detection of incorrect functioning of a solenoid valve set in a position corresponding to a pressure-reducing device set between the gas tank and a manifold for distribution of the gas to the delivery devices. The system is moreover able to detect possible gas leaks from the low-pressure part of the system. The electronic control means are moreover able to process the data regarding the high-pressure part of the system, according to a predetermined algorithm, during operation of the system in order to enable timely detection of incorrect functioning of the valve set immediately at the outlet of the tank or to detect a possible gas leak from the high-pressure part of the system.
