What are the advantages of using gasoline, LPG and CNG for cars?
Oct 21, 2017

LPG is liquefied petroleum gas, CNG is compressed natural gas, LNG is liquefied natural gas. The main component of LPG is propane, natural gas is compressed to 20MPa to form high-pressure natural gas called compressed natural gas (CNG); natural gas through ultra-low temperature to -162 ℃ formation of liquid natural gas called liquefied natural gas (LNG). Natural gas is the main component of methane (CH4), only a small amount of CO 2, H2S, N 2, He and other gases, flammable and explosive, full combustion, no carbon black and impurities, known as "green fuel." The critical gas pressure is 161795; the critical temperature is - 74. 18 ℃; the critical pressure is 5.26 M Pa; the boiling temperature is - 161152 ℃; the gas density is 01716 7 kg / m 3 in the standard state; 01426 kg / L. Vehicle CN G is the raw material gas by dehydration, desulfurization after pressurized filling of the gas, the quality requirements should meet the national standard.As a result of strict control of the harmful substances H2S and total sulfur content, so with the traditional fuel gasoline , Compared to diesel, its combustion after the pollution greatly reduced. According to information, CO reduced by 98%, HC by 70%, NO x by 39%, CO 2 by 24%, SO 2 by 90%. At the same time, because the octane number of methane is above 120, the antiknock performance is improved and the engine noise is effectively reduced. LN G is a cryogenic liquid formed by deep freezing after dewatering and desulfurization (1011325 kPa, -161125 ℃ ). After purification and freezing, the harmful impurities have been cleaned, the purity of CN G has been further improved, and thus the combustion products are more clean, more effective environmental benefits.
