Numerical Investigation of a 4-Stroke, 8-Cylinder Diesel Engine Using a 1-D Code

Emmanuel Anye


Diesel engines are important for the movement of people and goods. But they are also essential for generating electricity. While it is desirable that engines become, more efficient, reliable, durable and also environmentally-friendly, achieving this requires a better understanding of the complexities surrounding engine combustion processes. Recent technological advancements, including computer simulation have facilitated research and development of new diesel engines. Using a 1-D model of an 8-Cylinder, 4-Stroke diesel engine and applying a vibe combustion model, this study presents how in-cylinder processes affect diesel engine performance. The results reveal close proximity of the developed model to test bed measurements of the engine under investigation. Additionally, the findings demonstrate the capability of AVL BOOST to provide advanced models that allow for adequate prediction of engine performance.
