Abstract
The present study reports the results from a real experiments of the impact of the ignition angle on the harmful exhaust gases emitted by a gasoline engine. The experiments were carried out with a BMW 318 gasoline engine equipped with a MegaSquirt 3 electronic control unit and TunerStudio MS software, as well as a Kane AUTOplus gas analyzer. The main emissions considered in the study include some greenhouse gases such as carbon monoxide (CO), carbon dioxide (CO2) and unburned hydrocarbons (HC). The emissions of harmful gases were measured at 7 different engine speeds and 9 different ignition angles. The obtained data were used to compile regression equations that describe the relationship between the ignition angle, engine speed and the harmful emissions levels. The obtained results and derived equations offer specific recommendations for optimization of the ignition angle to minimize harmful emissions and improve the environmental performance of gasoline engines.
