SAE International has published the fully revised second edition of “1D and MultiD Modeling Techniques for IC Engine Simulation” (R-580), written by Angelo Onorati and Gianluca Montenegro of Politecnico di Milano, Italy.
The internal combustion engine remains the most widely used thermal machine in the world and will keep a central role in global mobility for decades to come. Even as alternative powertrains grow, optimized IC engines, often integrated in hybrid and electrified architectures, are essential for low fuel consumption, near-zero pollutant emissions and reduced CO2 output.
This second edition reflects the progress made in engine modeling and simulation over the past two decades. One-dimensional, three-dimensional and coupled 1D-3D techniques have become standard tools in modern engine design, allowing engineers to evaluate performance, efficiency and emissions in virtual engine environments before a single part is built.
The book brings together contributions from leading international researchers and industry experts. Topics include:
-
- 0D, 1D, quasi-3D and full 3D modeling approaches
-
- Turbocharging and aftertreatment systems
-
- Co-simulation and real-time applications
-
- Hydrogen and two-stroke engines
-
- Advanced thermal modeling techniques
It is written for engineers, researchers and graduate students who need a comprehensive reference for understanding, comparing and applying state-of-the-art IC engine modeling methods.
