They developed this especially for the 5.3 and 6.2 liters V8 EcoTec engines, including the GMC Sierra & Chevrolet Silverado pick-up trucks. GM (General Motors) has recently introduced a new technology: ‘Dynamic Fuel Management’, which is also called: Skip Fire. As much as we know Prins, though, we expect the new technology to be exclusively available on the brand's VSI conversion kits.We would like to inform you about one of our latest developments: a Prins LPG-system for the new GM Skip Fire Technology! The eVP-500 weighs in at just 800 g and is suitable for use in any vapour state sequential autogas injection system (for engines with direct and port petrol injection). Furthermore, there's a built-in pressure relief valve for enhanced safety of use and an integrated solenoid valve, cutting fuel flow into the combustion engine in case of engine failure or accident. The reducer includes a disposable liquid state LPG filter, easily accessible from the top.
Also, MAP connection is not required (actually, it's not even possible). The reducer is also installer-friendly – all the connectors (LPG and coolant inlets and outlets) are on the same side of the device, helping eliminate excessive hoses and cables. According to Prins, the eVP-500 retains autogas pressure determined by its software regardless of engine load, it doesn't suffer from pressure drift and is resistant to fuel cut-off pressure peaks (during engine braking). There are many other advantages of the design, though. © All connectors on one side, all fixing on the other - installers are bound to like the new product Incidentally, the choice of this material improves the reducer's heat efficiency. Apart from being very compact in size, it's also lightweight and that's thanks to its plastic-made housing. The vapouriser is membraneless, which makes it practically maintenance-free. This greatly enhances the component's capabilities, most importantly allowing for dynamic LPG output pressure regulation, depending on the engine's load at a given moment. Just like the eMV multivalve created by BRC (Prins' sister company inside the Westport Fuel Systems group), the eVP-500 (Electronic, Variable Pressure, up to 500 PS of supported engine power) reducer is electronically controlled.
It's small on the outside, but capable on the inside! The new eVP-500 reducer could be the answer to the needs of installers converting big and powerful vehicles, requiring ample and stable fuel supply. Ironically, modern cars' engines have fewer cylinders than their predecessors, yet their bays are increasingly cramped, leaving less and less space for autogas system components. © It may look like a CNG pressure regulator, but don't be fooled - it's a proper LPG reducer
