| Summary: | The development of motorcycle technology, such as the use of injection systems <br />
<br />
<br />
<br />
also increment of the compression ratio and octane numbers, followed by an increase in <br />
<br />
<br />
<br />
motor population which led to increased fuel consumption affecting various sectors. Sale <br />
<br />
<br />
<br />
of injection scooter in West Java 2014-2016 year was one of the biggest contributors with <br />
<br />
<br />
<br />
the amount of 2,260,470 motor. <br />
<br />
<br />
<br />
Performance test was performed on a four-stroke injection scooter motor with a <br />
<br />
<br />
<br />
compression ratio of 9.2:1(110cc); 9.5:1(125cc); 10.7:1(150cc); and 11:1(125cc) above <br />
<br />
<br />
<br />
the chassis dynamometer using RON90 (PL), RON92 (PM), and RON98 (PT) fuels from <br />
<br />
<br />
<br />
PT Pertamina. Testing based on ECE standard 15. Different driving modes were used to <br />
<br />
<br />
<br />
determine the effect of constant speed and torque, the entire cycle mode to simulate <br />
<br />
<br />
<br />
driving conditions on the road, and inertial sweep mode to determine motor power. <br />
<br />
<br />
<br />
The higher compression ratio and octane number increase power, efficiency, <br />
<br />
<br />
<br />
BMEP, and mileage. The test results were considered to represent each motor population <br />
<br />
<br />
<br />
to determine the effect of use with the assumption of use for 57 minutes / day and fuel <br />
<br />
<br />
<br />
type PM 59%, PL 36%, PT 5%. The increase in population in 2014-2016 resulted in an <br />
<br />
<br />
<br />
increase in fuel consumption of 1.05 million bbl of energy 138,147 TOE or 1.34 trillion <br />
<br />
<br />
<br />
rupiahs or 33.96 tons CO₂ emissions. However, the increasing use of high compression <br />
<br />
<br />
<br />
ratio motors in 2015-2016 resulted in fuel consumption savings of 1.74% compared to <br />
<br />
<br />
<br />
2014-2015. If 2,260,470 motors were used, the high compression ratio motor has saved <br />
<br />
<br />
<br />
4,616,227 liters of fuel or 159,354 GJ or 36.90 billion rupiah or 0.93 ton CO₂. |
