Performance in relation to the torque, E10 in the case Half Open Throttle at 2000 rpm reduces the engine torque by 3.8 %, at 4000 rpm the engine torque is reduced by 1.6%. E10 in the case of Wide Open Throttle at 2000 rpm reduce the engine torque by 3.4%, and at 4000 rpm reduces the torque by 1.2%. In the case of E20 at Half Open Throttle and rpm 2000 the engine torque reduces by 5.8%, and at 4000 rpm increases by 2.7%.</p><p>The addition of a swirl generator will increase the engine performance in the case of E20 at Half Open Throttle. The average engine torque increases from 10 until 13 %, in the case of Wide Open Throttle the engine torque increases by 9%. In the case of E10 with Half Open Throttle the engine torque increases by 9%, and with Wide Open Throttle increases by 8,5%. </p>}, number={6}, journal={Asian Journal of Applied Sciences}, author={Cahyono, Beny and Mardji, Taufik Fajar Nugroho, and Abu Bakar, Rosli}, year={2017}, month={Jan.} }
