CNG is compressed natural gas. This is natural gas of various pressures, located in the pipeline and compressed at high pressure using a CNG compressor (200 or 250 bar).
ADVANTAGES OF CNG VEHICLES
CNG is 70-80% more economical than petrol vehicles and 40-50% more economical than LPG vehicles.
When using CNG, which does not harm the engine, an oil change is carried out on average every 35-40 thousand k.
Engines running on natural gas are more durable and have a long service life than engines running on other fuels. Since natural gas is a clean fuel, the frequency of maintenance is reduced.
Given that natural gas is structurally different from liquid fuels, there is no risk of theft. This prevents the risk of fuel theft, especially in large fleets.
Transportation of natural gas by pipeline does not create additional costs that arise due to danger, environmental pollution, etc. as it happens when transporting gasoline, LPG and diesel fuel by land transport.
The autoignition temperature of gasoline is 300 °C, the ignition temperature of LPG is 400°C, Autoignition temperature of CNG is 650°C. Due to the physical characteristics of CNG, it is more difficult to ignite.
Natural gas, which is much lighter than air, mixes with air quickly in an accident compared to bottled gasoline or LPG, which are heavier than air.
Natural gas, which is much lighter than air in the event of an accident or leakage, quickly mixes with air and, compared to other combustibles (LPG, gasoline, etc.), do not accumulate on the ground and creates an explosive and flammable situation. Minimal risk of fire. Ignition is possible at a gas/air ratio in volume terms of 5~15%.
Minimum maintenance costs.
Today, in many pollution-sensitive countries, buses, taxis, and public transport use natural gas. They benefit from the safety, economy, and environmental friendliness of natural gas.
When mixed with other fuels, natural gas produces less than 90% nitrogen and less than 25% carbon monoxide.
Natural gas does not contain aldehydes and other airborne toxins like other alternative fuels.
Engines running on natural gas compared to engines running on other fuels, noise pollution is 30% less.
Natural gas creates a very low level of the greenhouse effect.
Natural gas is not poisonous and corrosive gas, therefore it does not pollute groundwater.
Extends the life of methane.
Natural gas is currently the most reliable, environmentally friendly, and economical type of fuel available. Compared to gasoline, LPG, and fuel oil, natural gas is the most economical. That is, natural gas provides savings compared to gasoline by 62%, fuel oil, and LPG by 40%.
