Abstract

This study aims to evaluate the effects of diesel-microalgae biodiesel blends (Microalgae Biodiesel Oil, MBO) on the performance and emissions of a Hyundai D4CB diesel engine. The research methodology is based on numerical simulation using the Diesel-RK software, in which the engine is analyzed at engine speeds of 1400, 2000, 3000, and 3800 vòng/phút while operating with conventional diesel fuel (Diesel No.2) and different MBO blending ratios. The simulation results indicate that as the proportion of MBO in the fuel blend increases, engine power and torque tend to increase, while CO₂ and SO₂ emissions are significantly reduced compared to conventional diesel fuel. However, fuel consumption, NOx emissions, and soot formation show an increasing trend when fuels with higher MBO content are used. Based on these results, MBO fuel blends demonstrate potential as an alternative fuel for diesel engines, contributing to emission reduction and diversification of fuel sources. Nevertheless, to enable the use of pure microalgae biodiesel or higher blending ratios, further experimental studies and engine modification solutions are required to improve performance and operational reliability under real operating conditions.
