Abstract
In today's modern world the internal combustion engine has a predominant role in stationary low power generation and a virtual monopoly in mobile applications. Concentrations emitted from the internal combustion engines thus build up to levels sufficient to have adverse effects on plants and animals. In Compression Ignition (CI) Engines turbulence of the charge plays a vital role in combustion process. The generation of suction swirl using a shrouded inlet valve is one way to achieve the desired level of turbulence. The shrouded inlet valve is capable of modifying the droplet size distribution of the fuel spray as well as producing a more ignitable and burnable mixture, which contributes to the reduction in the NOx content in the exhaust. The experimental part of the paper involves the fabrication of shrouded valves of different length of shroud. Load test and emission tests were carried out on a stationary four stroke C.I.Engine. The test results are analyzed and it is concluded that lower levels of emissions are achieved by shrouding. Even though there is a slight decrease in power output from the engine, the advantages of lowering the emission levels achieved through shrouding provides the basis for the trade off between power and emission.
