The EVO injector rail combines the technical characteristics of a high-end injector rail with excellent resistance to impurities in the gas, so that the use of a gas filter is not absolutely necessary. The gas exiting the filter exits from inlet “A” and fills the common chamber of the injector group. With appropriate dosage, the gas exits the injectors via nozzles “B” and reaches the intake manifold and thus the engine via a specific connection. The injectors are driven by the gas control unit and connected to it via the “D” connectors.

The injectors are of one size, the different flow rate is determined by the installed nozzles. The increasing figure of numbers written on the metal nozzles and the colouring of plastic nozzles shows the large size of the injectors.
