TESTING SPEED LIMITER INTEGRATED FATIGUE ANALYZER AND ITS EFFECT ON FUEL EFFICIENCY AND REDUCTION IN GREENHOUSE GAS EMISSSION ON TRUCK ENGINE WITH 17 TON

Mechanical Engineering

The Speed Limiter Integrated Fatigue Analyzer-SLIFA test on a 17-ton capacity truck engine was conducted to find out how much fuel efficiency can be saved after the SLIFA-installed on truck, fuel is the dominant factor in the transportation business and its cost is number 1 that should be efficient, the purpose of this test is to investigate whether the use of SLIFA can have a positive effect on fuel consumption when the truck operates. Another positive impact of fuel savings is to reduce greenhouse emissions. the methods for this test is dynamic testing which is done by pairing a flow meter device connected to the fuel supply to the fuel injection pump. The emission test using an exhaust emission opacity tester device to determine the level of smoke thickness which is found by the residue of combustion. The truck is run on Jakarta-Bekasi-Bandung route with full load of 17 tons. Total distance is 100 km and the average speed in the urban road is 60 km / h on the highway 70 to 100 km / h with maximum engine speed of 3200 rpm, the result of the test done when the truck is not in install the SLIFA tool get the value of fuel efficiency used fuel ratio A + B + C / Total ratio = 1: 3.43 km / l with the calculation rate of supply rate 20 Lph (53 gph) return rate 10 lph (2.2gph) total value rate based on digital fuel mater readings is 0.46 gph or 0.12 lph, then after installing SLIFA on the truck the fuel total ratio 1:4.02 km/l. For emission test result before installing SLIFA at 22 and after installing SLIFA at 16.6. This reducing of gas emission and fuel consumption are about 28.14 % and 32.53% respectively after SLIFA installation on truck engine. With this significant result, SLIFA could be valuable consideration to enhance performance of fuel consumption and reduce gas emission
