Redesign and Adaptation of a Homogeneous Charge Compression Ignition (HCCI) Engine to Obtain Parameters Affecting Combustion Initiation

This technological development project focuses on the redesign and adaptation of an existing diesel engine to convert it to Homogeneous Charge Compression Ignition (HCCI) technology. The main objective is to investigate the parameters affecting HCCI combustion initiation and evaluate their effects on performance and pollutant emissions, addressing the need for cleaner and more efficient engines amid increasing environmental regulations and fuel costs. The methodology involves geometrically modifying the single-cylinder engine (combustion chamber and compression ratio) and installing an advanced electronic injection system, such as Pandoo Box Inject or Haltech 750 controllers, to achieve precise homogeneous mixture dosing. Independent variables such as lubricant characteristics, climatic conditions, and fuel compounds will be studied, measuring dependent variables like the air-fuel ratio, mean effective pressure, and emissions. The expected outcome is a significant reduction in emissions like NOx and PM, improved thermal efficiency, and a contribution to Sustainable Development Goals related to affordable and clean energy, and industry, innovation, and infrastructure.<br/><br/><b>Goal</b>: <br/>To reconstruct a single-cylinder internal combustion engine to adapt a Homogeneous Charge Compression Ignition (HCCI) system to improve performance characteristics and reduce generated emissions compared to a conventional operating cycle.<br/><br/><b>Research lines</b>: <br/>Alternative energies
