Experimental investigations of real time secondary CO-injection of water - Diethyl ether solution in Di-diesel engine fuelled with palm kernel methyl ester

In this investigation tests were conducted on single cylinder diesel engine fuelled with neat diesel and biodiesel palm kernel methyl ester as a base line fuel with secondary injection of water-dee solution through the inlet manifold. a real time control systems consists of electronic unit pump that delivers 5% to 25% vol. water-dee solution through injector tip mounted nearer to the inlet manifold under a pressure of 3 kgf/cm2. nox emissions reduced to a level of 500 ppm with simultaneous reduction of soot especially for pkme. however for 15% vol. of water-dee injection the hc emissions are closely tallying with that of neat diesel. a global overview of the results has shown that the 15% water-dee solution is the optimal blend based on performance and emission characteristics. © school of engineering,taylor's university.
