Analysis of the CI Diesel Engine's Performance Swirl Concept Use at the Inlet Manifold

Abstract

The researchers were motivated to conserve fossil fuels and control emissions due to the depletion of fossil fuels and the pollution they caused. Efficient combustion, which is made possible by even air and fuel mixing in the cylinder, reduces emissions. The current study's goal is to improve the cylinder's swirl motion effect, which improves performance and lowers emissions. Three parameters can be changed to create the swirl motion in the engine: the cylinder head, piston crown, and inlet manifold configuration. In this thesis, a fresh air fan is installed at the intake manifold to effectively create swirl motion in the engine.

This experiment is conducted on a four-stroke, single-cylinder, water-cooled diesel engine using diesel, biodiesel blends, and standard pistons with thermal barrier coatings of 100 and 200 microns. The piston crown is coated with a thermal barrier. Results without swirl motion are compared and the performance, emission, and combustion parameters with swirl motion are analyzed.
