Because vaporization happens inside the manifold, the system does not require a traditional reducer/vaporizer tied into the engine's cooling system. 2. Core Hardware Components

I will cite the relevant sources. Vialle LPi Technical Manual: The Definitive Guide to Liquid Propane Injection Systems
The represents a major shift in alternative fuel technology by injecting Liquefied Petroleum Gas (LPG) into an engine as a liquid rather than a vapor. According to the Vialle LPi Technical Manual , this approach eliminates the power loss typical of older vapor-phase systems, leverages the cooling effect of expanding liquid for better cylinder volumetric efficiency, and integrates cleanly with modern automotive Engine Control Units (ECUs). lpi+vialle+technical+manual

A standout feature of the Lpi Vialle Technical Manual task-oriented practical cases
Before delving into the manual itself, it is essential to understand what makes the Vialle LPi system unique. Unlike traditional autogas systems that rely on vaporizers to convert liquid propane into a gaseous state before injection, Vialle’s LPi system injects LPG in its liquid form directly into the inlet manifold. This approach represents a that delivers substantial performance advantages. If you need help diagnosing a specific error
Sourced from the crankshaft position sensor or camshaft sensor to determine engine speed and timing sync.
A dedicated serial/USB interface connector used to interface with Vialle diagnostic software. 4. Operational Phases
The Vialle system relies on the vehicle’s original Engine Control Unit (ECU) for primary calculations. The Vialle LPi computer acts as a "coupler" or slave unit. It intercepts the gasoline injection signals, modifies the pulse duration to compensate for the different energy density of LPG, and drives the LPi injectors. 2.

: Infobulletin LSI210005 (dated June 10, 2021) details firmware version 2.28 for the LiquidSi ECU, introducing six improved features including lower minimum RPM (from 600 to 500 RPM), increased maximum pressure drop detection for empty tank detection (up to 6 bar), enhanced nozzle delay handling for start-stop systems, and a new injector offset correction table for more stable fuel supply at load changes.
Features a pressure transmitter (0-30 bar range) that converts fuel pressure into a 0-5V signal for the ECU.
The control unit performs several essential functions:
One of the system’s most elegant features is that it requires only the petrol injection times to regulate the LPi system. Pump speed, gas injection pressure, and injection timing are all calculated from the petrol injection signals, maintaining all original OBD diagnostic functions. The factory programming for each specific vehicle means extensive calibration after conversion is unnecessary.
