Research on Intake System of Motorcycle Engine to Obtain High Torque at Low and Medium Speed

Abstract:

The new intake system is designed and the intake pipe is changed in order to get high torque at low and medium speed. After the intake parameters are changed, the intake dynamic effect is utilized to increase volumetric efficiency and torque at the low and medium speed by theory analyses. Through further research, it is found that intake pipe length has a quite great influence on torque characteristic. Extending intake pipe length can improve engine torque at low and medium speed and its maximum torque point is shifted from high speed scope to low and medium speed scope.
