Development of hydrogen fuelled transport engine and field tests on vehicles

摘要

Three wheelers have been employed as a common transport vehicle in many developing countries. The present work discusses the test results on a single cylinder typical three-wheeler vehicular engine in lab and subsequent development of Hydrogen fuelled three wheelers. The paper also highlights the modifications done on the test rig to ensure smooth operation without any undesirable combustion phenomena such as backfire and rapid rate of pressure rise. The engine was developed for bi-fuel operation with modifications required in the existing designs of gasoline engine to achieve hydrogen operation. Performance and exhaust emission characteristics of the engine were experimentally evaluated to meet the requirements for vehicular operation. The engine developed peak torque of 13.2 Nm 3200 rpm while operating at lean conditions. Development of fifteen hydrogen-fuelled three wheelers equipped with various safety features are also discussed in the paper. (C) 2016 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
