Investigating the social benefits of substituting CNG for other fuels to reduce pollution in Sheberghan City

Abstract

One of the main factors contributing to increased pollution is the presence of old and smoky vehicles. The excessive increase of such vehicles in cities, pollutants have risen, leading to various diseases such as respiratory disorders, cardiovascular diseases, and even climate change. Additionally, the excessive use of fossil fuels, especially gasoline, incurs two drawbacks: it causes environmental pollution and increases prices, which in turn opens the door to the use of other fuel materials, including natural gas. The results of numerous studies indicated that the use of Compressed Natural Gas (CNG) in vehicles can be an effective solution for addressing environmental pollution problems in cities and can lead to savings in fuel costs. The aim of this research is to compare CNG gas with other fuels and to assess its effectiveness in engines. The method of this research is based on a promotional objective and, from the perspective of data nature, is analytical-descriptive, with data and information collection carried out through library methods. The results of this research indicate that compressed natural gas is a safe and clean fuel, causing less environmental damage compared to other fuels, and a greater number of vehicles also use it. Therefore, it can lead to the development of the compressed gas industry. Considering the rich natural gas resources of the city of Sheberghan and attracting government investment, the importance and position of compressed gas have become one of the best alternatives to fuel materials in internal combustion engines.
