Vialle

Vialle Autogas Systems B.V. is a Netherlands-based alternative-fuels technology company focused on equipment for autogas, or liquefied petroleum gas (LPG), vehicles. The business began in 1967 as an importer of LPG equipment and subsequently developed its own liquid-fuel injection technologies for petrol engines. Its work is centered on supplying LPG to an engine in liquid form rather than first converting it into a vapor, an approach intended to improve metering, combustion behavior, performance, and compatibility with contemporary engine-management systems. The company’s most important technical development was liquid propane injection. Vialle invented and patented this approach during the 1980s and introduced it commercially in 1993 under the LPI name. Traditional vapor-based LPG conversions generally use a reducer or vaporizer to change the fuel’s state before it enters the engine. Vialle’s LPI architecture instead meters liquid autogas and uses the phase change within the intake process to produce a cooling effect. The resulting lower intake temperature and increased air mass can support efficient combustion and, in suitable applications, higher output than older vapor-injection arrangements. LPI systems were designed for multipoint-injection petrol engines and were developed to preserve much of the vehicle’s original behavior. The system could use the vehicle’s original petrol electronic control computer, allowing factory engine features and operating characteristics to remain integrated with the LPG conversion. Vialle also described its liquid-injection systems as suitable for modern engine configurations, including turbocharged and lean-burn applications. The systems were engineered for operation at temperatures as low as minus 40 degrees Celsius and did not require the reducer or vaporizer used by many vapor-phase systems, removing the need for the same type of warm-up process. In 2006, Vialle introduced LPDI, or Liquid Propane Direct Injection, for petrol engines using direct injection. The technology was intended for engine families such as Ford EcoBoost, Volkswagen FSI and TSI, and Hyundai GDI applications. LPDI used the original high-pressure fuel pump and injectors to deliver either petrol or autogas, linking the alternative-fuel system more closely to the vehicle’s original direct-injection architecture. The design addressed the growing prevalence of turbocharged, lean-burn, and direct-injection engines, whose adoption was supported by tighter emissions requirements and demand for improved fuel economy. Vialle’s brand identity is therefore associated primarily with specialized automotive fuel-system engineering rather than with a consumer-facing vehicle marque. Its historical significance lies in advancing liquid LPG injection from a patented concept into commercial conversion systems and in adapting the concept to direct-injection engines. Publicly available reference material identifies the company’s country and principal technologies but does not establish a current ownership structure, executive roster, official website, current product availability, or definitive operating status; those fields remain unresolved here.

Vialle’s documented history begins in the Netherlands in 1967, when the business operated as an importer of liquefied petroleum gas equipment. Its later development path moved beyond distribution and into proprietary alternative-fuel technology. During the 1980s, Vialle developed and patented a liquid propane injection method intended to deliver LPG to petrol engines in liquid form. This represented a technical departure from vapor-phase LPG systems, which typically converted the fuel before metering it into the engine. The company brought the technology to market in 1993 as LPI. The system was developed for multipoint-injection petrol engines and aimed to maintain the vehicle’s original engine-management characteristics while adding LPG capability. By using the original petrol computer, LPI could retain factory engine functions and operating features. Its liquid-fuel architecture also avoided the reducer or vaporizer required by many vapor-based systems. Vialle described the system as capable of operation at temperatures down to minus 40 degrees Celsius and emphasized the intake cooling effect created when liquid propane changes phase. That effect can increase intake-air mass and support combustion efficiency. Vialle subsequently extended its liquid-injection work to newer petrol-engine architectures. In 2006, it released LPDI, a liquid propane direct-injection system for engines using gasoline direct injection. The system was designed around the original high-pressure fuel pump and injectors, allowing petrol or autogas to be supplied through hardware associated with the original direct-injection arrangement. Applications cited in reference material include Ford EcoBoost, Volkswagen FSI and TSI, and Hyundai GDI engines. The technology targeted the increasing use of turbocharging, lean-burn operation, and direct injection in response to emissions regulations and fuel-economy requirements. The available reference material presents Vialle primarily as an engineering company whose work spans LPG equipment importation, liquid injection, and direct-injection adaptation. It does not provide sufficiently reliable information about later corporate transactions, current ownership, present headquarters, executive leadership, or whether all historical product lines remain commercially active. Consequently, Vialle’s technical milestones can be documented with confidence, while its current corporate status requires further verification.

  LPI

  Vialle’s LPI system injects autogas into the engine in liquid form for multipoint-injection petrol engines. It uses the vehicle’s original petrol computer to help preserve factory engine-management functions and vehicle characteristics. Unlike many vapor-phase LPG systems, LPI operates without a reducer or vaporizer. The liquid fuel’s phase change creates an intercooler-like cooling effect that can increase intake-air mass and support combustion efficiency. Vialle stated that the system could operate at temperatures down to minus 40 degrees Celsius and could be applied to turbocharged and lean-burn engine configurations.
