Lean burn performance of a hydrogen-blended gasoline engine at the wide open throttle condition
Wang, Shuofeng; Ji, Changwei; Zhang, Bo; Liu, Xiaolong - In: Applied Energy 136 (2014) C, pp. 43-50
The performance of a hydrogen-blended gasoline engine at lean and the wide open throttle conditions was investigated. A … hydrogen port-injection system was adopted to introduce the hydrogen into each cylinder. The engine was operated at 1400rpm and … two hydrogen blending levels of 0% and 3%. The excess air ratio was raised from 1.00 to about 1.45 for a given hydrogen …

Performance and emission analysis of a compression ignition
Hirkude, Jagannath Balasaheb; Padalkar, Atul S. - In: Applied Energy 90 (2012) 1, pp. 68-72
The aim of the present work is to prepare waste fried oil methyl ester (WFOME) as a diesel fuel substitute. High viscosity and poor volatility are the major limitations of waste fried oil for utilization as a fuel in diesel engines. The cost of waste fried oil methyl ester (WFOME) production is...
