PENGARUH VARIASI ROLLER 8 GRAM, 9 GRAM, 10 GRAM, 11 GRAM DAN 12 GRAM MENGGUNAKAN PEGAS CVT 1000 RPM TERHADAP KINERJA MOTOR HONDA SCOOPY 108 CC
Abstract
Along with the rapid development of science and technology especially in the automotive industry, various technologies have been developed to improve the performance and efficiency of the motorcycle, them motorcycle with CVT automatic transmission (countinously variable transmission). The advantages of the CVT system (countinously variable transmission) can provide changes in speed and torque from the engine to the rear wheels automatically with a very precise ratio of ratios without having to move gears, such as on a conventional transmission motorcycle engine. Therefore motorcycle users are increasing, the need for transportation is very helpful for daily activities and routines.
This research was conducted to determine the impact of using standard rollers and rollers combined with torque, power, and acceleration on automatic motorcycles Honda Scoopy 108 cc. After replacing the CVT roller and spring it is expected to improve the automatic motorcycle performance of Honda Scoopy 108 cc. The research method used is the experimental method and carried out at the rotating speed (rpm) change, by turning on the engine and holding the gas at 3000 rpm engine speed after stabilizing at 3000 rpm engine speed then the gas is with drawn to 9000 rpm.
From this study it was found that the standard 12 gram roller with a standard CVT spring, the highest power produced by the Honda Scoopy automatic motorcycle after varying the roller (8 gr), (9 gr), (10 gr), (11 gr), and (12 gr) ) obtained on the condition of the 8 gram roller using a CVT spring 1000 rpm which is equal to 8.2 hp at a rotating speed of 4588 rpm. The highest torque is obtained by using an 8 gram roller and a CVT spring 1000 rpm which reaches 14.88 N.m at engine speed of 3701 rpm
