Abstract In the case of a diesel engine, air is very important for increasing and decreasing engine parameters. On IC engines, air enters through an inlet valve passage, which is more critical. This is a promising combustion strategy for achieving homogeneity that combines the benefits of both SI and CI engines. Turbulence must be created in engines to achieve homogeneity, and as a result, swirl flow will be activated in the ignition chamber. In light of the stream properties of air streaming in different structures of the CI engine’s air inlet channel, many types are available to create swirl flow for enhancing engine efficiency and lowering emissions. The advantages of an HCCI engine is that it produces low NOx emissions by burning a lean mixture of charge. Working in cylinder with emission in exhaust gas are HC, CO, CO2 and Nox of CI engine, this is based on chamber pressure, temperature, loss of heat transfer on chamber surfaces, and working in cylinder with HC, CO, CO2 and Nox of CI engine. Changes to the inlet route must be performed to create turbulent conditions in order to improve IC engine characteristics. Turbulent will improve the uniformity of the air/fuel mixture at all ignition chamber entry points. This research is aimed at lowering emissions by modifying the inlet poppet valve of a four-stroke single-cylinder diesel engine. For modified inlet poppet valves of HC, CO for modified (masking) inlet poppet valve (4M), and CO2 for modified (masking) inlet poppet valve (4M), emission levels are lowered (2M).

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.
