Conventional combustion engines will continue to be the most widely used engine systems in the automotive industry for the foreseeable future. It is, therefore, crucial that we continue to improve our understanding of this complex system with the aim of producing cleaner and more efficient engines.

In this talk, Professor Chris Brace will introduce some of the difficult-to-model aspects of an engine’s operation that show evidence of both stochastic and deterministic behaviours.

Usually, these aspects are glossed over, because they are hard or impossible to predict. Increasingly though these phenomena must be understood and controlled in order to extract ever more efficiency and cleanliness from this venerable workhorse, which powers the vast majority of all cars, trucks and boats throughout the world.


Professor Chis Brace

Professor Chris BraceChris Brace, a world-leading automotive researcher, is Professor of Automotive Propulsion and Deputy Director of the Powertrain Vehicle Research Centre at the University of Bath. In addition to being seconded to IMI for six months during the 2016-2017 academic year, Chris leads a wide portfolio of powertrain-based research projects with a common theme around the measurement, analysis and control of multi-cylinder engine systems running under dynamic operating conditions.

All his research is conducted in collaboration with industry, most notably Ford Motor Company and Jaguar Land Rover.

During his secondment to IMI, Chris will collaborate with IMI’s Commercial Research Associates to develop a proposal for new interdisciplinary research aimed at gaining a better understanding of important but complex behaviours seen in engine systems. An example of this is the formation and migration of condensation in engine exhaust gasses. Improving our understanding of this is important, as it will enable the recirculation of a higher proportion of exhaust gasses, at optimal temperature and pressure. In turn this will lead to cleaner and more efficient engines, which ultimately carries huge environmental benefits.
