Why Do CNG Vehicles Consume Too Much Gas?
1 Answers
When using natural gas, excessive fuel consumption is related to improper installation and adjustment of the compressed natural gas pressure reducer. The advantages of natural gas vehicles include the following: 1. Higher economic benefits: For the same equivalent heat value, countries around the world generally control the price of 1 cubic meter of natural gas to be half that of 1 liter of gasoline or diesel. If the thermal efficiency of various engines is relatively similar, the fuel cost of natural gas vehicles is approximately half that of gasoline or diesel vehicles. This compensates for the shortage of liquid fuel supply caused by the increasing number of vehicles and significantly reduces operating costs. 2. Better social benefits: Compared to petroleum fuels, gaseous fuels have smaller energy losses during preparation and emit fewer harmful pollutants into the atmosphere. From the perspective of fuel sources, they are more environmentally friendly. 3. Relatively safer: The gas cylinders or tanks of CNG, LNG, and LPG vehicles are sturdy and reliable. Natural gas itself is lighter than air (except for LPG), so any slight leakage quickly disperses into the atmosphere. All components of the gaseous fuel system, especially the sealing parts, undergo rigorous inspection. Therefore, natural gas is relatively safer as an automotive fuel.
