Target of ACNN National and Strategic Project

According to a number of infrastructural reasons such as high age-average of the vehicles in use, old fashioned production technologies in manufacturing excessively consuming engines, inadequate infrastructural facilities for more economic transportation systems and highly subsidized fuel price, consumption rate of the fossil fuels in Iran are pretty higher than the international standards. On the other hand, the existing production capacity limits of the country’s refineries have led to the procurement of a considerable portion of the vehicles’ fuel supply from overseas resources; the fact which imposes an excessively costly burden upon the country’s economy.

On the basis of the above status quo and in order to accomplish the national strategic policies in the energy section and have the common fossil fuel substituted by CNG (compressed natural gas), the Ministry of Oil assigned the Iranian Fuel Conservation Company right after its establishment to implement the National Plan of “CNG Management”.

The executives of the national plan of “CNG Management” are trying to introduce CNG as an efficient and logical alternative fuel to regulate the rampant rate of petrol and gasoline consumption by vehicles, place a reducing control upon the import of these products and take steps towards the localization of CNG industry. In order to achieve this goal, we need to consider a number of policies as listed below:

- Making use of more appropriate alternative fuels

- Reducing petrol imports and preventing outflow of currency

- Overcoming the international economic sanctions in order to make petrol sanctions ineffective

- Reducing environmental pollutants

- Reducing waist of the national fossil fuel resources

- Increasing families’ purchasing power by the implementation of “Targeted Subsidies Plan” and increasing the price of Forms of Energy.


As time goes by, machine-life issues and dependency on diverse technologies tend to prove more tangible and sometimes even intolerable in different dimensions of people’s life. Automotive industry has got an outstanding position on this ground: lots of facilitations have been made but a lot of difficulties have come across as well (e.g. air pollution majorly), so that in developed societies people welcome a certain day as the “Car Free Day”.

A few solutions to these problems have been figured out, one of which is substitution of fossil fuels by CNG, as effective as it’s assumed to be in the reduction of environmental pollution.

Some characteristics of compressed natural gas (CNG) in comparison to other fuels have given gas burning vehicles advantages upon other types. To name a few we may consider gas-burning engines’ less exhaust of suspended particulate matter (spm) in air, more controlled emission of poisonous and harmful pollutants, considerable reduction in the amount of emitted Sulfur Oxide and Sulfur Dioxide and also cheaper fuel price. Besides, CNG engines produce less noise and run with less vibration as compared to diesel ones.

CNG also has other advantages to be named as quality and efficient combustion, high Octane rate and less emission of Carbon Monoxide and unburned Hydrocarbons. CNG engines are also more secure in car accidents. As a relatively lighter matter, CNG leakage will ascend and disperse into the air, while other fuels will remain as flammable spots on the ground for some time. Besides, CNG has a spontaneous combustion degree of 650 C as compared to that of 350 C for petrol.

In spite of all these advantages, CNG engines have got some disadvantages in comparison to fossil fuel burning ones as well, such as relatively costly distribution and storage, more expensive station construction, more expensive vehicles, shorter distance coverage, extremely heavy mounted tanks and more complicated and problematic executive procedures.

Despite the above mentioned disadvantages, the abundance and low price of this fuel have made CNG a prevailing common car fuel in many countries.

Adequate resources, quality combustion and compliance of its exhaust rate with the environmental regulations have made CNG the main alternative fuel in the most parts of the world. Considering its low energy density, CNG needs to be capsulated in accordingly-designed metal or composite cylinders under 200 bar compression to be used as car fuel.
