Performance of CI Engine Using Swirl Type Retrofit

Abstract

Due to its higher thermal efficiency diesel engines are used worldwide in transportation, agriculture and many. The problem associated with these diesel engines are less efficiency and release of toxic emissions like CO, HC and NOx to the atmosphere. These problems can be overcome by use of alternative fuels and by engine modification. Modification of fuel spray is one of the methods to achieve complete combustion of fuel, which helps in achieving higher efficiency and reduced toxic emissions. This work is carried out by using an attachment for fuel injector known as retrofit. Experiments were conducted using retrofit attached to fuel injector nozzle and found to be increased in efficiency of the engine and reduced toxic emissions when compared with conventional injector without retrofit.
