: The phase change from liquid to vapor absorbs heat, increasing intake charge density.
The core innovation of the Vialle LPi system is that it does not convert the LPG into vapor before injection. Instead, it maintains the propane in a liquid state, which increases the density of the fuel, improves volumetric efficiency, and results in improved power output and torque, closely matching petrol performance.
Leaking LPi injectors dripping liquid fuel into cylinders post-shutdown. To further optimize or troubleshoot your specific vehicle
Ensuring the LPG used is of high quality, as the fuel itself lubricates the internal pump. 5. Where to Find the Manual
The system utilizes a continuous loop. Liquid LPG flows from the tank to the fuel rail, and excess fuel returns to the tank.
Most LPG systems are vapor injection — they turn liquid propane into gas before feeding it into the intake. That’s fine, but it robs some density and response. Instead, it maintains the propane in a liquid
Engineered injectors that handle liquid fuel, rather than vaporized gas.
The LPI Vialle technical manual highlights several advantages of the system:
The LPi system works in harmony with the engine’s original Gasoline Electronic Control Unit (ECU). The Vialle manual details that the injector driver intercepts the gasoline injection signals and translates them into signals appropriate for the LPi injectors.
