Once you've optimized your engine's performance, it's time to validate your results. This involves:
Before placing components, define your global properties in the Project Window. Set the ambient pressure (e.g., 1.013 bar) and ambient temperature (e.g., 293.15 K). Define your fuel properties, such as lower heating value (LHV) and liquid density. Step 2: Establish Boundaries Post-Processing & Analyzing Results When AVL releases a
In a marine diesel engine study, researchers used AVL Boost to simulate typical faults. By altering the UPD (e.g., advancing the start of combustion by 5°), they found that the maximum combustion pressure increased by 17.4%. When they deactivated one cylinder (by replacing its pressure trace with a motoring curve), the effective fuel consumption rate increased by nearly 15%. This demonstrates how UPD can be used to investigate “what‑if” scenarios without physical engine modifications.
