This study aims to assess the impact of loading on a Kirloskar 3.7 kW single-cylinder, four-stroke, compression-ignition engine fuelled by both diesel and biofuel. We specifically investigated the influence of inlet air pressure on the engine’s performance and emission characteristics. . In the experimental setup, the inlet air pressure was systematically increased from 1 to 2.5 bar. Notably, emissions like CO and HC exhibited a significant decrease, while a slight increase in brake power and NOx emissions was observed. Employing a statistical approach, we established a regression model to predict the performance and emission levels of the diesel engine, particularly when operating on biofuels. The use of a multi: regression model allowed us to derive an empirical relation for the evaluation of brake power (BP), hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) in the context of diesel engine operation.
The empirical equations for BP, CO, HC and NOx as developed by a solution of
the multi-regression model in terms of the inlet air pressure and biofuels
blend were as under:
BP (kW) = (-) 0.0305 P (-) 0.0005 BLEND + 2.65
CO (%) = (-) 0.0029 P (-) 0.0006 BLEND + 0.1211
HC (PPM) = (-) 20.7 P (-) 0.3050 BLEND + 65.925
NOx (PPM) = 102 P + 2.16 BLEND + 249.98
