If the engine idles roughly on LPG, the injectors might require cleaning to remove oily deposits. 5. Obtaining the Manual
The final chapters cover the physical placement of the LPG tank (often an under-floor ring tank) and the meticulous routing of the wiring harness and fuel lines to avoid heat, abrasion, and other damage.
LPI requires consistent high pressure to prevent evaporation. The manual covers electrical specifications and pressure regulation (typically 3 to 5 bar above manifold pressure). Working on these components requires strict adherence to fuel safety standards to prevent leaks or ignition. B. The LPI ECU and Injectors lpi vialle technical manual top
Apply a neutral soap solution or leak-detecting fluid to identify bubbles. Check "Doughty" washers at the coupling block. Faulty injectors or water damage to electrical pins

If the engine idles roughly on LPG, the
Designed to meet modern environmental standards for CO2 and NOx reduction.
Because the gas is injected in liquid form, it behaves closely to petrol, resulting in similar power output. LPI requires consistent high pressure to prevent evaporation
By injecting fuel directly at the inlet valves, the system prevents the accumulation of gas in the intake manifold, which eliminates the risk of consequential damage from backfires. Vialle LPi Technical Manual
Leaking LPi injectors. When the engine is turned off, residual pressure remains in the fuel rail. If an injector seal is compromised, liquid LPG leaks into the combustion chamber, creating an overly rich mixture.
