technical manual

It sounds like you're looking for a related to the LPI Vialle system—likely for LPG (autogas) or alternative fuel conversions—specifically the "Top" model or series.

7. Maintenance Intervals (TOP schedule)

Symptom: LPG runs but lacks power → Check liquid pressure drop under WOT (should stay >4.5 bar) → Inspect top cover diaphragm (no visible crack = no guarantee) → Perform injector leak test (liquid LPG drip = bad injector)

According to the official technical documentation , the manual is structured into several core technical areas:

LPI Vialle controller: The controller is the brain of the system, regulating propane injection and monitoring system performance.
Liquid propane tank: The tank stores liquid propane, which is supplied to the system.
Propane injection valve: The valve controls the flow of liquid propane into the air intake system.
Air/fuel mixer: The mixer ensures a precise air/fuel mixture for efficient combustion.

Full hydraulic circuit diagrams (Tank to Pump to Injectors).
Oscilloscope waveforms for injector current ramping.
Stepper motor logic for the fuel pump control valve.
Fault tree analysis (FTA) for every Diagnostic Trouble Code (DTC).
ECU pin-out data for the Vialle LPI ECU vs. the vehicle's OEM ECU.

Visual inspection: Check for leaks, damaged hoses, and secure mounting of tanks and components.
Leak testing: Perform pressure and soap-bubble tests on fuel lines and fittings.
Electrical check: Verify battery voltage, ground connections, and ECU power supply.
Injector test: Measure resistance and perform an activation test using the diagnostic tool.
Sensor verification: Confirm correct readings from pressure, temperature, and lambda sensors.
Software: Connect to ECU, back up existing settings, then update or calibrate per manufacturer procedure.

Always follow proper installation and configuration procedures.
Ensure proper ventilation when working with propane.
Never attempt to service the system while it is in operation.

: The tank contains a high-pressure pump that circulates liquid LPG through the lines and maintains the necessary pressure to prevent vaporization before injection. Coupling Block
