CNG; ” Compressed Natural Gas ” or “Compressed Natural Gas” so called natural gas at high pressure 200/250 bar, in particular with compressor and compressed form.
CNG Natural Gas uses :
1) CNG AUTOGAS is used in vehicles as an engine fuel.
2) CNG ENERGY is filled into special transport containers and transported to consumers who will use natural gas and consumed by reducing the pressure.
CNG can be used as autogas and engine fuel especially in automotive industry . CNG used in all kinds of vehicles in the automotive industry, trucks, vans, buses, minibuses, cars can be used in all kinds of transportation vehicles. Compressed natural gas is the most intensively used area in the world. Fuel prices are high, octane value is 120-125 octane, clean and full combustion, not to mix with oil as a result of prolonging the life of the engine, does not cause an increase in fuel consumption over time, the danger of explosion ( 5 % – 15% Air-Gas mixture ratio) to other fuels The fact that CNG is a low fuel compared to the fuel has been encouraged.
- Studies and research on the use of natural gas vehicles in many western countries on a fast pace is . 200 million of the 600 million cars and trucks available in the world are in the USA . It is known that in the US, where 50% of the air pollution occurs from the exhausts of these vehicles, CNG vehicles are produced and some of the existing vehicles are converted to CNG . In Turkey; In Istanbul, Ankara, Adana, Sakarya, Bursa, Afyon, Bolu , Konya , Diyarbakir, Kocaeli, Gaziantep and Eskisehir, a number of projects have been developed to reduce the air pollution caused by the exhaust gases of municipal buses , and the use of buses whose conversion to natural gas has been completed. NGV Global 201 companies in New Zealand of 7 according to the year of data; The number of natural gas vehicles in the world 20 million , the number of filling stations 20,000 around , naturally in Turkey , the number of gas-powered vehicles 4000 around , while the number of filling stations only one is around 6.
- In the US, California, student shuttle buses use CNG on a mandatory basis. In the Netherlands, the use of CNG on canal boats has been completed. In many countries, only CNG-driven vehicles can enter city centers. These examples CNG security and superior emission emphasizes ness.
- In terms of engine maintenance, the vehicle’s periodic maintenance time is prolonged, reduced vibration reduces wear, CNG does not contain pollutants, oil life is prolonged and performance is improved. When the monetary value of these positive values is added to the significant advantage in the CNG price, the saving rate increases compared to other fuels.

Advantages of Auto-CNG:
CNG is more economical and cleaner than other fuels . Natural gas is the cleanest fuel compared to other fossil fuels as it does not produce toxic and corrosive products that affect the environment . It burns easily even in cold weather as it enters the engine directly as gas. Ignition temperature of natural gas is 650 ºC; The gasolines of 350 ºC . Since it does not contain additives like gasoline, it leaves less waste in the engine after combustion. Due to this feature, we can say that it extends the life of the engine. Due to the high octane number, the combustion efficiency of the engine is higher and in this respect it is a useful fuel for the engine. Since natural gas is transported by pipelines, it does not create danger, extra costs and pollution in motorways according to the fuel and other fuel types carried by road . Safer and less risky than other fuels.
How Much does Auto-CNG create saving?
Per 100 km from 7 liters of gasoline a vehicle consuming;
Approximately 6.5 m³ CNG
Or it consumes approximately 9 liters of LPG .
Between 50-60% compared to gasoline and 30-35% more saving compared to LPG .
How much does Auto-CNG save ?
On average, a vehicle consuming 7 liters of gasoline per 100 km; It consumes approximately 6.5 m³ CNG or about 9 lt LPG. On the basis of fuel consumption ; Between 50-60% compared to gasoline and 30-35% more saving compared to LPG. In terms of price, savings amount can be calculated according to current prices.
Retrofitting of Diesel Engines to CNG ( AUTO-CNG)
- In single fuel systems, the operating principle of the engine is converted from the diesel cycle to the Otto cycle. Diesel engines CNG‘to conversion from the combustion to be controlled and regular gasoline engine principle ( Otto -cycle) is to be passed. Thus, the spark-ignition engine is switched on. For this purpose, the injectors are replaced with spark plugs, and the cylinder head of the engine is changed.
- First in Turkey as of the year 2010 115 IKARUS İETT of buses from MAN diesel and CNG to transform a single-fired successfully completed and the project has attracted attention all over Turkey.
