AC injector rails are designed for autogas sequential injection systems in cars with internal combustion engines. They ensure the precise dosages of vaporized gas to the engine inlet and each cylinder.
The high durability of all the AC rails off has been confirmed in long-distance road tests for various makes of cars and various road and weather conditions.
The advanced materials used for the construction of AC injector rails provide higher durability and a faster response.
Additionally, the AC rails are provided with 2Ω coils to avoid the overloading of control systems. The coils have been equipped with IP67 rated connections.
The main component is a body made of anodized aluminum. The connections are made of brass and sealing is based on rubber compounds compatible with other elements. All materials comply with the strict requirements of Regulations 67 and 110.
AC W01 – designed for most engines available on the market.
