Viewers look into the fourth generation LPDi vehicle unveiled for the first time in the world.
The fourth generation LPG Direct Injection (LPDi) vehicle, which attracts attention as the next generation LPG vehicle, made its debut.
At the International Exhibition on Environmental Technology & Green Energy (ENVEX), which opened on June 11, Hyundai Motor displayed the LPDi vehicle ‘Sonata Nu 2.0’ installed with the industry-first advanced LPDi engine that directly injects liquid LPG, attracting keen interest of the audience.
The development of the world’s first cutting-edge LPDi engine has been carried forward under a follow-up program of the Environment Ministry’s ECO-Star Project, and its commercial production system is expected to be established by the end of 2014.
The new LPDi engine, which was successfully developed by a research team in Korea for the first time in the world, adopted the mode of combusting fuel by directly injecting liquid LPG into the main combustion chamber. By applying the principle of standardized GDi engine to LPG, the new engine can sharply reduce emissions of hazardous substances, such as total hydrocarbon (THC) and NOx, compared to using gasoline, while performing output equal to gasoline. Thus, it realized eco-friendly technology and high performance simultaneously.
In particular, it satisfied both criteria of European Union’s EURO 6 that rigorously controls emission of micro particles and NOx from vehicle’s exhaust gases and those of the U.S. Super Ultra Low Emission Vehicle (SULEV), the most stringent regulations on gas emissions in North America.
The new engine is identified to be outstanding in eco-friendly property as it can reduce emission of nano particles, which are harmful micro particles with less than 1 micrometer in diameter, by over 90% compared to gasoline vehicle in the same class. It also reduced emission of poly aromatic hydrocarbon (PAH), a carcinogen, by over 90% compared to gasoline engine, while slashing emission of volatile organic compounds (VOC) that cause photochemical smog by a half.
