GAS INJECTION SYSTEM
The model AT09 LPG reducer is a single stage reducer for LPG sequential injection systems, homologated ECE 67R-01, originated from the previous model AT07. The AT09 reducer is equipped with an integrated filter unit and an inlet solenoid valve. The pressure at the outlet is adjustable from 0,9 to 1,8 bar (pressures referred to the reducer not connected to the engine).
Available in 3 different versions:
BASIC: without additional heating
with additional post-heating of the LPG at the outlet, that allows higher gas flow and higher gas temperature at the exit.
with additional pre-heating of the liquid LPG at the inlet, that allows extra higher gas flow and higher gas temperature at the exit.
Model OMVL Dream XXI(Italia)
DREAM XXI is the latest gas injection system designed and developed by OMVL.
It can be installed on all fuel injected vehicles powered by LPG or CNG. The system is fully homologated in
compliance with the latest safety standards for gas fuel system (67R01 and R110) and keeps emissions well
within the limits established by the strictest standards (EURO4).
DREAM XXI is extremely reliable under all vehicle operating conditions, and guarantees excellent performance in
terms of comfort and driveability.
Great efforts were made by OMVL to integrate the mechanical and electronic subsystems, to allow an easy and
quick installation, and to guarantee efficient and reliable operation.
The regulator completely vaporises LPG reducing its pressure to 0.9 or 1.2 or 1.7 bar, depending on engine size and power. It is a two stage membrane unit with pilot circuit and water-gas heat exchange. This heating is particularly efficient due to the specific heat exchanger configuration. A pressure compensation system maintains a constant pressure difference upstream and downstream of the injection unit at every engine power and load, ensuring a stable and precise carburation. The solenoid shut off valve cuts gas flow when the engine is switched off or petrol fuel is selected.
