Abstract

In this present work a study about influence of the Exhaust gas recirculation EGR in the cylinder upon the performance and emission of a single cylinder diesel direct injection engine is presented In order to achieve good swirl intensity in the cylinder a grooved brass piston with 9 grooves with Diamond mesh cut configuration on the piston crown is selected With this modification turbulence in the combustion chamber is enhanced Also in the present work performance of the engine is done with diesel along with 10 15 and 20 EGR with 9 grooved piston GP with Diamond mesh cut configuration
