The diesel engine remains one of the key components
in the global economy, transporting most of the worlds
goods. To cope with stricter regulations and the continuous
demand for lower fuel consumption, optimization is
a key method. To enable mathematical optimization of
the diesel engine, appropriate models need to be developed.
These are preferably continuously differentiable, in
order to be used with a gradient-based optimization solver.
Demonstration of the optimization-based methodology is
also necessary in order for the industry to adapt it. The
paper presents a complete mean value engine model structure,
tailored for optimization and simulation purposes.
The model is validated using measurements on a heavyduty
diesel engine. The validated model is used to study
the transient performance during a time-optimal tip-in, the
results validate that the model is suitable for simulation
and optimization studies.
