Abstract: In This study presents an experimental investigation on a 4-stroke Direct Injection Diesel Engine run with Diesel. The efficiencies of the engine were compared when run using both a normal piston and a piston with grooves. The grooves were designed to create turbulence and improve the thermal efficiency of the engine. The results showed that the grooved piston improved the engines performance under all load conditions.
