Abstract
A significant proportion of our daily routine has always been spent traveling from one place to another place. Fossil fuel, particularly petroleum fuel, consumption is steadily rising as a result of population growth which in parallel raises the concerns over the possible environmental issues such as greenhouse gases (GHG) emissions released to the atmosphere that contribute to acid rains and global warming.In order to protect our planet from major environmental challenges that we are likely to face later in this century, some international coordinated efforts have been adopted in order to tackle climate changes. In Paris, on 12 December 2015, 196 Parties to the United Nations Framework Convention on Climate Change (UNFCCC) reached a landmark agreement so-called The Paris Agreement to combat climate change which describes the gravity of this issue.
Inevitably the growth of population causes a simultaneous increment in human mobility requirement that leads to the widespread presence of internal combustion (IC) engine which is the power source and mechanical heart sustaining the concept of contemporary mobility.To this issue, automotive sectors made a crucial effort and devoted to a strict de-carbonization process to push the European transport sector to the 2050 target and the use of Low Carbon Alternative Fuels, like Compressed Natural Gas, will play a fundamental role to quicken this process.Natural gas (CNG) is considered as an alternative vehicle fuel because of its economic and environmental advantages which is a clean fuel with CH4 as its major component which produces 20% less CO2 than the other conventional fuel such as gasoline, that is considered to be one of the most favorable fuels for engines
