Description

Detail about CNG kits for injection systems) UNITE GAS Multipoint Sequential Injection System represents a mew generation of fuel (gasoline/CNG) conversion system. The principle is used by the CNG ECU to calculate the injection timing applied to the CNG control unit translates gasoline actuations into an appropriate control for CNG injectors. In order to maintain the coherence with the gasoline system, the CNG ECU drives CNG injectors in the same sequence as gasoline injectors . CNG ECU through model based software strategies is able to transform gasoline injection into CNG injection timing reconstructing an appropriate calculation chain optimized for CNG. UNITEGAS can use different types of injectors according to the specifications of the specifications of the application. UNITEGAS is minimally invasive with respect to the original gasoline engine management system. UNITEGAS can be easily integrated with the main engine management function as mixture control, cut off , EGR, purge canister, etc and auxiliaries engine management functions as air-conditioning , power-steering, electric loads, etc. The CNG ECU is able to calculate CNG injection timing by using specific information such as CNG injector rail pressure, CNG temperature, engine coolant temperature, engine RPM and battery voltage, in addition to the inputs of the gasoline ECU.
