The ECU is calibrated to the specific LPG conversion vehicle and engine. LPG injection signal optimises the flow and LPG injection timing. The effect is similar to intercooling on turbocharged cars.Īn Electronic Control Unit (ECU) controls the various components of the liquid injection LPG conversion, including the injectors. This cooling effect increases the density of the air-fuel mixture, ensuring power and torque are maintained and fewer CO 2 emissions. This vapourisation process rapidly cools the surrounding air.

The LPG immediately vapourises after being injected. The injectors spray the liquid LPG into the intake manifold. The system pumps LPG at high pressure from the LPG tank to the engine inlet manifold via a set of liquid LPG injectors. Liquid Phase Injection (LPI) Systems – Liquid Injection LPG Conversion It truly is the best LPG conversion system (best LPG system). You get a substantial LPG fuel consumption savings (LPG average mileage) with an LPDI LPG conversion, combined with equal or better LPG engine conversion performance, LPG conversion MPG, great drive-ability and lower tailpipe emissions. The LPG conversion price for an LPDI LPG conversion would be at a premium, compared to other systems. LPDI systems are the latest generation in LPG conversion technology. The best LPG conversion system (best LPG system) is arguably the liquid phase direct injection (LPDI) system. Best LPG Conversion System – Best LPG System The LPG instantly vaporises, cooling the combustion chamber fuel-air mixture during the compression stroke, with further performance and emission improvements. Liquid phase direct injection (LPDI) is a direct injection LPG conversion (gas conversion) and are the most advanced LPG conversion, injecting liquid LPG directly into the combustion chamber.

The fuel vaporising in the intake manifold cools and increases the density of the intake air, substantially increases power output, improves fuel economy and has lower emission, when compared to VPI systems. Liquid phase injection (LPI) systems inject liquid directly into the intake manifold, where it vaporises, not using a converter.This has been the most popular type LPG conversion in recent years. Vapour phase injection (VPI) LPG conversion use a converter-and-mixer system, but the gas exits the converter under pressure and is injected into the intake manifold.Įlectrically controlled injectors improve the metering of fuel to the engine, fuel economy and power, as well as reducing emissions.The liquid fuel is converted into vapour and then mixed with air before going into the intake manifold. Converter-and-mixer systems are the oldest style of LPG conversion (gas conversion), dating back decades and still widely used.These additions enable the LPG conversion to run on both fuels. In simple terms, LPG conversion is the addition of a second fuel system including an LPG tank, intake manifold modifications, a new ECU and various fittings. It is the automotive Holy Grail of a high performing LPG conversion vehicle with low cost fuelling… LPG Conversion The LPG instantly vaporises, cooling the combustion chamber fuel-air mixture during the compression stroke, with further performance and emission improvements. MVDLE are single-stage automatic shutoff valve, slow-opening, fast-closing.Īsk us for engineering or product support.Liquid Direct Injection LPG Conversion – LPG Conversion – Gas Conversion Direct injection LPG conversion is injecting liquid LPG directly into the combustion chamber. MVD are single-stage automatic shutoff valve, fast-open, fast-closing. The Dungs MVD and MVDLE safety shutoff valves are suitable for natural gas, propane, butane, air and other inert gases. The Dungs MVD/6 and MVDLE/6 are recommended for industrial and commercial heating applications that require one or two automatic shutoff valves in series. The Dungs MVD/6 and MVDLE/6 – Pipe sizes are from 1/2″ to 3″ NPT, electrically operated, normally closed, automatic solenoid shutoff valves for gas burning equipment.
