The Comparison of Fuel Consumption for Small Gasoline Engine Fuelled by Commercial Gasoline Fuel in Thailand on Different Conditions
This research aimed to study the Comparison of Fuel Consumption for Small Gasoline Engine Fuelled by Commercial Gasoline Fuel in Thailand on Different Conditions, as produced by small gasoline engine performance testers. The researchers used Gasoline, Gasohol 95, E20 and E85 with Honda GX 200 engine. The test machine consisted of (1) a brake pump and brake calipers, (2) Drive Shafts and Levers Load pressure gauge, (3) Speed sensor of engine, and (4) Fuel cylinder of each type and oil shutoff valve. Digital display all these devices was installed on the same structure as the engine used in the test. The test was conducted at the constant engine speed 2,500 and 3,600 rpm, with a load at 2 Nm and 4 Nm.
The performance test results revealed that the workload 2 Nm with the brake specific fuel consumption of gasoline, gasohol 95, E20 and E85showed gasoline having the lowest fuel consumption. The used oil was most cost effective and cost saving with gasohol E85 and 4Nm workload. Specific fuel consumption of E20 and gasohol had the lowest fuel consumption. It was the most cost effective. Based on the tests at engine speed of 3,600 rpm constant load at 2Nm and 4Nm, the performance results of the engine performance were at 2Nm workload. Of the specific fuel consumption of gasoline, gasohol 95, E20 and E85. gasohol 95 had the lowest fuel consumption. It was the most cost effective. At 4Nm workload, the specific fuel consumption of gasoline had the lowest fuel consumption. It was found that the used oil gasohol E20 was the most cost effective.
