Hydrogen Fuel In 6-Stroke IC Engines And Reduction Of Noxemission Using Hollow Fiber Membrane Module

This paper deals with the use of hydrogen as a fuel for 6-stroke internal combustion engine. The properties of hydrogen suited for using it as a fuel is clearly discussed. The essential modifications are made in the design of the 6-stroke internal combustion engine, air injection system, fuel injection system and spark plug to rectify the disadvantages of the IC engine operated using hydrogen fuel. Using hydrogen as a fuel for IC engine reduces the exhaust like CO, HC etc., but the amount of NOx emission increases due to 78% of N2 in the air and they are easily combusted in this process. TheNOx emission is controlled by the application of the hollow fiber membrane module on the air injection system. This system replaces the use of EGR for reduction of NOx emission. NOx in the 6-stroke engine exhaust gas is closely related to the peak cycle temperature and available amount of oxygen in the combustion chamber, so NOx emissions from 6-stroke IC engines can be reduced by reducing the peak temperatures of combustion. The hollow fiber membrane module separates Nitrogen from ambient air and gives Nitrogen enriched air (NEA).Nitrogen is obvious diluents of heat and it does the work instead of exhaust gas. This reduces the peak cycle temperature and available amount of oxygen.The membrane material used is perfluoropolymer. The performance characteristics and emission characteristics of hydrogen powered IC engine are compared with the gasoline engine and the conclusions are made. The results of reduction in NOx test are also presented. Keywords- Hydrogen Fuel, IC Engine Reduces, Co, HC etc. (NEA)
