The heat transfer enhancement for engine block by adding solid nanoparticles to liquid is significant topics recently. The nano materials have high heat transfer rate. Most of the researches have been conducted nanoparticles alone in the engine. It is the right time to have alternative materials including nanoparticles in the cooling media. The lemon juice is traditionally one of the best cooling medium. An attempt is made by adding lemon juice (natural) as an additional fluid with base fluid to investigate the heat transfer rate. Now it is planned to run the engine at different load conditions and at constant flow rate of coolant (Lemon juice+ Base fluid +Al2O3nano particles) to obtain the heat transfer rate. This work included the heat transfer rate by forced convection. The juice which is extracted from naturally available lemon and dispersed in the base fluid as the lemon is easily soluble. The different concentrations of lemon juice in the ratio of 1%, 1.5 % and 2 % by volume have been added with base fluid (70% water +30% Ethylene Glycol).
