Pemodelan variasi weight roller CVT terhadap torsi mesin K20 menggunakan metode logika Fuzzy

This research was conducted to find the gray value of the Weight roller weight test against the engine RPM of a motorized vehicle, torque is the desired result. Large torque but still within reasonable limits of fuel use, namely 1:15. After testing using the Dyno test, the results are processed using fuzzy logic. The use of weight rollers is indeed proven to be able to increase the torque value of a machine, but the results can change depending on the processed value, therefore it is assisted by a fuzzy system to get maximum results. The use of a 13 gr weight roller produces a torque of 08.89 Nm at 5000 RPM which is smaller than the torque on a standard size Weight Roller which is 10 gr.
