Engineers are advancing the science of Design of Experiments for model-based calibration and control of powertrain systems to meet increasing regulations, reduce cost, and improve effectiveness.

Developing a control system for today's engines is as much an exercise in computer science and advanced mathematics as in combustion physics.

Complex control systems are needed to run complex engines. Common diesel engine features now include variable-valve timing, direct injection, and variable geometry turbocharging, among many others. While good for fuel economy and controlling emissions, completely mapping an engine's response to so many inputs is impractical using “brute force” methods. These engine maps are vital in creating a control system.
