Electronic Kit Controller to Increase a Motorcycle Engine's Power and Torque

Abstract

The aim of this work is to develop an electronic kit controller for motorcycle engine, to be able to increase power and torque than standard one. The kit developed is based on Arduino Uno microcontroller. The test engine is a 108.2 cc cylinder capacity Honda PGM-FI eSPwith compression ratio of 9.5:1. The testing engine has applied electronic control unit (ECU) to maintain its combustion closed to stoichiometric condition at certain air fuel ratio (AFR) which is considered as the most optimum engine performance. It has an Oxygen sensor of narrow band type on the exhaust manifold. In this work, the kit will decrease the AFR slightly in order to have more power and torque for the testing engine. Dynamometer test is carried out to evaluate power and torque parameters of the test engines. Emission test is also conducted to have AFR and emission level. The results show that the electronic kit controller developed as part of this work increases the test engine's power and torque. The emission levels are still below the permitted level.
