- High performance Up To 500hp
- Single stage
- Pressure regulation software Adjustable:
- Pressure setting: 50-380kPa absolute
- No derive or pressure peaks
Working principle
When LPG mode is selected, the tank Multivalve will be supplied with 12 V. By activating the tank Multivalve, the liquid LPG flows to the eVP-500 reducer.
The engine coolant warms up the liquid LPG inside the eVP-500 reducer. The LPG will become vapour. The vaporized LPG will flow through a filter unit is placed between reducer and injectors. It filters the vaporous LPG
to prevent contamination of the gas injectors. A combined PT-sensor is installed in the filter unit. This sensor measures the gas temperature and system pressure. These signals are processed by the AFC-3.0 DI to obtain the proper mixture.
Function
➢ Vaporizing liquid LPG
➢ Absorbing sufficient heat to vaporize the required amount of LPG
➢ Create a Flow and Pressure regulation
➢ Providing the engine with sufficient vaporous LPG across its entire load range
