SUMMARY The goal of this project is to simulate a common rail direct injection diesel engine and draw conclusions about its emissions and performance. Based on these results, we aim to determine the best biodiesel blend ratio using numerical data. To carry out the simulation, our team used AVL Boost software.
We set up the basic engine parameters, calculated the valve curves, scale factors, and selected appropriate elements for the simulation. After completing the simulation, we verified the results using the SR Lay Decman formula to ensure the accuracy of our model. We then created different test cases for engine speeds ranging from 1000 to 4000 RPM under full load conditions. We used various biodiesel blend ratios (B10, B20, B50, etc.), ran simulations, and analyzed data on power, torque, in-cylinder pressure, NOx, CO, and soot formation.
From our analysis, we found that a blend of 20% biodiesel and 80% diesel is the most suitable ratio. This blend strikes a good balance between maintaining engine power and reducing harmful emissions without needing to modify the engine.

OVERVIEW OF THE RESEARCH TOPIC 1.1 Reason for choosing the topic The environment plays an important role in the life of humans as well as all other creatures on Earth. Not only does it provide an ideal living environment, it also gives people resources to economic development, cultural, social. Nowadays, environmental pollution has become a difficult problem not only in one country or one region but is a common concern of all humanity.
In the process of socio-economic development along with population growth in countries around the world, it has led to great impacts on the environment. Specifically, global climate change, causing the greenhouse effect, ozone layer degradation, acid rain, etc. More pollution is the emission of dust and toxic gases from the engines of motor vehicles.
