%0 Journal Article %T EXPERIMENTAL INVESTIGATIONS OF REAL TIME SECONDARY CO-INJECTION OF WATER ¨C DIETHYL ETHER SOLUTION IN DI-DIESEL ENGINE FUELLED WITH PALM KERNEL METHYL ESTER %A Y. V. V. SATYANARAYANAMURTHY %J Journal of Engineering Science and Technology %D 2012 %I Taylor's University %X 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. %K Water-DEE solution %K PKME %K Smoke %K Nitrogen oxides %U http://jestec.taylors.edu.my/Vol%207%20Issue%206%20December%2012/Vol_7_6_711-721_SATYANARAYANAMURTHY.pdf
