PENGARUH PENAMBAHAN ZAT ADITIF ALAMI PADA BENSIN TERHADAP PRESTASI SEPEDA MOTOR 4-LANGKAH
Abstract: The quality fuel
affects combustion because the fuel quality will get better combustion.
Therefore, it is necessary to improve the quality of the fuel to produce
combustion. Such an increase in the octane rating of the fuel can result in
increased good quality of the fuel. One method used is the addition of natural
additives in the fuel. Tests were performed using a motorcycle test engine 100
cc 4-stroke is running test (road test and acceleration), and stationary
testing. The test road test conducted by a distance of 10 km with an average
speed of 50 km / h test aims to get the value of fuel consumption. Furthermore,
using the acceleration test speed 0-80 km / h and 40-80 km / h which aims to
get the fastest acceleration time. Then the stationary testing done on rotation
1.000 rpm and 3.000 rpm with a 5-minute aims to get the value of fuel
consumption at rest. This test uses a natural variation in the dose of the
gasoline additive used is 1:4, 1:6, 1:8, and 1:10. On testing fuel consumption
with the distance 10 km can be seen that the concentration of 1:6 is the best
concentration that can reduce fuel consumption by 23,31% (136 ml), compared
with natural gasoline without additives (177,333 ml). Average time acceleration
0-80 km / h resulted in the concentration of the best natural additives 1:4
that is with an average acceleration of 10,847 seconds (20,69%). In testing
acceleration 40-80 km / h obtained for the concentration of 1:8 with an average
acceleration of 6,993 seconds (21,83%). Tests of stationary fuel consumption at
1,000 rpm for 5 minutes in to the best performance at a concentration of 1:8
that is 33,91% (12,667 ml) whereas at 3.000 rpm stationary best performance is
obtained at a concentration of 1:10 30,71% (14,334 ml).
