1.6.2 Pressure regulator Landi IG1
The IG1 pressure regulator is a two-stage type. It is heated with engine heat by the engine coolant. The integrated
valve (1 to 3) also filters incoming gas. The pressure regulator adjusts the output pressure to just 1.0 bar (100 kPa)
above the pressure at the compensation port (6) (MAP). The first stage has an operating pressure of 1.6 bar above
atmposperic pressure. The second stage ensures further pressure reduction and is adjustable.
Specifications:
First stage operating pressure:1.6 bar (160 kPa) relative
Second stage operating pressure:.1.0 bar (100 kPa) rel.
