Experimental Investigation of the Effect of Injection of OxyHydrogen Gas on the Loading characteristics of Diesel Engine
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 7
Abstract
Oxy-Hydrogen generator, which produces a mixture of hydrogen and oxygen by water electrolysis has many advantages over using pure hydrogen as an additive fuel in Internal combustion engines due to the elimination of aboard storage problems of hydrogen. In this paper, an experimental exploration was carried out in order to study the effect of addition of oxy-hydrogen gas intake air manifold on loading performance characteristics of a diesel engine at different operating conditions. The experimental work was performed on a test rig comprising a four stroke 5.67 liters water-cooled diesel engine. Instrumentation included devices for measuring engine speed, load, exhaust temperature, fuel consumption and inlet air flow rate. Tests were conducted at a speed of 1500 rpm and different engine load at different oxy-hydrogen generator supplied currents and different electrolyte concentrations. The addition of H2O2 gas reduces the specific fuel consumption at all percentage of electrolyte concentration and all values of oxy-hydrogen generator supplied current. Fuel saving ranging from 1.62 at 10 A to 6.47 % at 26 A at 5% electrolyte concentration while at 25 % of electrolyte concentration the fuel saving ranged from 6.47 at 10 A to 13.29 % at 26 A. volumetric efficiency decreases by about 4.5 % when the supplied current is 26 A at 5 % electrolyte concentration and about 5.5 % when the supplied current is 26 A at 25 % electrolyte concentration.
