ET-86-3 A research study submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Environment, Resources and Development Research Studies Project Report (M. Eng.) - Asian Institute of Technology, 1986 In the face of heavily dependent for its commercial energy supply on imported petroleum, both crude oil and petroleum products. The study of using natural gasoline CNGL) as an alternative source of energy substituting gasoline was a prospect to increased domestic supply for petroleum product in the country. As an alternative fuel for spark ignition engines, performance tests were conducted on a 10 - HP Briggs & Stratton spark ignition engine coupled to a Zollner- dynamometer AC100 of Eddy-current type. The performance evaluation was focused on the feasibility of using natural gasoline and blending NGL with premium gasoline as a fuel. The results indicated that blending NGL with premium gasoline on the proportion of 50-to 50 C NPG55) was a border line of the highest percentage of NGL in the mixture that can be used as a fuel without any engine modification. The economic evaluation was focused on NPG55 price and the consequences of its adoption. The results indicated that NPG55 adoption was faced with a high NGL ex - refinery price, thus the NGL ex - refinery price was considered and proposed. Furthermore NPG55 can be substituted for regular gasoline with saves foreign exchange and supplement for natural gas (domestic resources) utilization, but have a reduction in tax revenue.
