CNG (Compressed Natural Gas) Fueling system refers to the system that supplies natural gas to NGV(natural gas vehicles), that uses natural gas for its engine.In particular, NGV use natural gas for its fuel, contributing to conservation of petroleum and reducing pollution in metropolitan areas. Compared to gasoline, natural gas produces less no family gas and CO by 30~50%, CO2 by 20~30%,and produces no SO family gas. Also the Octane number is 130, which is higher that(96) of gasoline, reducing fuel consumption which improved engine compression ratio. Other benefits of natural gas include: Superior engine ignition at lower temperature; excellent anti-knocking capability; and lower fuel logistic cost with nation-wide pipe lines.
CNG Compressor
Performs the most important task to compress the low-pressure gas to high-pressure(250bar) gas from the fuel pipe and then deliver it to storage cylinder or dispenser.
Must have a device installed inside, which blow-down the high-pressure gas remaining at each pipe and heat exchanger, when the compressor is stoped.
It must be equipped with heat exchanger that decrease the temperature rise caused by the heat generated when gas is compressed to high-pressure, as well as filter that removes potential foreign materials
