LPG and CNG conversion system for sequential injection vehicles
GP20 injectors, allowing to meet the latest generation engines requirements, are included into Alba 32, the kit intended for LPG and CNG conversion of automotive spark-ignition engines. Available for 3- and 4-cylinder vehicles, it was created with a view to preserve main characteristics of BRC gaseous injection systems, such as the significant gas ECU diagnostics feature.
