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

Each injector triggers independently, aligning perfectly with its respective cylinder's intake stroke to optimize emissions and fuel economy. The Starting Phase

Traditional LPG systems rely on an engine-heated reducer-vaporizer to convert liquid propane into a gas before induction. The Vialle LPi system bypasses this step entirely. By injecting LPG in its liquid state, the system takes advantage of the physical properties of evaporating propane to optimize engine efficiency. The Evaporative Cooling Effect

Standard LPG systems rely on an engine-bay regulator to vaporize fuel using engine coolant. The Vialle LPi system eliminates the regulator entirely. Instead, an integrated fuel pump submerged within the LPG tank maintains the fuel under high pressure throughout the entire fuel loop. lpi vialle technical manual top

: A specific black steel tank equipped with an internal diaphragm pump. This pump circulates liquid LPG and maintains a system pressure of 5 bar above the tank pressure to prevent vapor bubbles. LPE (LPG Control Unit)

The LPE performs a sequential transition. It shuts off petrol injectors one by one while simultaneously activating the corresponding LPG injectors. This seamless handoff eliminates engine stumbling or hesitations during transition. 5.
