Hydrogen Fueled Multi-cylinder Spark-ignition Engine and Storage Apparatus-A New Approach 2007-01-4274
In order to find effective solutions to the problem of air pollution due to combustion processes, attention is paid to the research projects to find alternative sources of energy to replace the rapidly depleting petroleum resources. This paper discusses the experimental studies carried out in a multi-cylinder four stroke gasoline engine using hydrogen as the sole fuel. Apart from this, a new approach on the storage apparatus has also been attempted. The main problem in the gaseous hydrogen storage has been taken care with a new system which is comprised of a capsule that contains nanomaterials in it. Hydrogen is stored in that capsule and it is directly fitted with the engine. This capsule would replace the current fuel storage cylinders. It occupies less size and it also takes care of the safety issues. The performance and emissions characteristics of the hydrogen-fueled engine at constant speed compared with that of gasoline operation has been presented. Reduction in power output, increased thermal efficiency and only NOx emissions are observed with hydrogen-fueled operation.
