Wire harnesses and fuse holders—typically situated in the engine compartment—must be moisture-sealed to prevent voltage drops or system dropouts. Common Faults and Solutions Probable Cause Manual Recommendation Rough running / Misfires Clogged liquid gas injectors or bad LPG fuel quality. Clean or replace injectors; check fuel rail pressure. No pump noise at start Blown fuse or faulty PTC pump motor.
Engineered injectors that handle liquid fuel, rather than vaporized gas.
The PTC pump is a wear item, often lasting between 100,000 and 150,000 kilometers.
At idle (0.8 mg/cycle), the intake air temperature drops by ( 15–20^\circ C ), mimicking intercooling. The technician must ensure the intake manifold gaskets are rated for -40°C, as local freezing can occur. lpi+vialle+technical+manual

Specifically designed to inject liquid propane directly into the engine’s intake ports.
This article explores the technical architecture of Vialle’s LPI systems, the components detailed in their technical manuals, and why this technology remains relevant today. No pump noise at start Blown fuse or faulty PTC pump motor
Attaches to a clean, unpainted factory grounding point. Poor grounding causes voltage drops, erratic pump speeds, and injector driver errors. Injector Interception Strategy
