Evaluation of Comparative Analysis in the Use of Petrol and Compressed Natural Gas (CNG) As Vehicular Fuel

Abstract

Petrol driven engines are the major contributor of environmental pollution. Environmental problems are well talked and written about but public and private sectors sensitivity remains very high. However, amidst the understanding that petrol driven engines contributes to about 15% green house gases, petrol shows no sign of quitting the energy scene. Therefore, one wonders if petrol engines offer better performance than CNG engines?. This paper is intended to answer this question by not just revealing the limitations delaying the full utilization of CNG but by carefully evaluating recent studies carried out on comparative studies of CNG engines and petrol engines. The evaluation is done based on; Performance, Storage and Safety, Maintenance, Emissions, Economy and Cost, Technology, Refueling, Refueling Station Cost, Engine Conditions, Legislation and Incentives, Adequacy of fuel supply, process efficiency, ease of transport and safety of storage, modifications needed in the distribution/refueling network in the vehicle, fuel compatibility with vehicle engine (power, emissions, ease of use, and durability of engine)and the Market place which is drawn from experimental results and conclusions made from recent studies.
