Design and Analysis of Single-Cylinder 22 HP Hybrid Powertrain for Motorcycles

A single-cylinder engine of 22 HP plus 10 HP hybrid powertrain for motorcycles is proposed in this paper. An electric DC brushless motor, connected via crankshaft to the 249.4cc four-stroke internal combustion engine (ICE), drives a continuous variable transmission (CVT) to the rear wheel for propulsion of vehicle. A rule-based controller structure is established for management of power from both the ICE and motor to reduce fuel consumption and achieve charge sustaining. With the help from Matlab/Simulink programs, simulations and assessment of the efficacy in emission reduction of the proposed hybrid motorcycle under ECE-R40 driving cycle are analyzed.
