Diesel and gasoline engine research has, over the past few years, been extended into the systems environment. This has come about because of the increasing complexity of engine platforms as a result of new and emerging enabling technology, coupled with an associated increase in the number of degrees of freedom which contribute to performance.

Subsequently, performance, measurement, control, optimisation and calibration studies need that systems focus with expertise capable of interrogating engine operating strategies.

Designing for Experimentation

A key strength of the expertise within the Centre is in designing experimental programmes which are robust in approach with exceptionally high standards as regard measurement accuracy and repeatability. Usually, a DoE approach is adopted which provides the capability to reduce the intensity of experimental programmes while providing key statistical capability coupled with the identification of system interactions to assess the overall results.

Capability

Three industry standard transient test platforms with an unfettered approach to process control coupled with expertise based on know-how provides significant capability to undertake complex and demanding experimental programmes. Experimentation is fully supported by the usual predictive tools.

Examples of specific research expertise

• Performance evaluation of engine systems;
• Engine and engine system calibration, optimisation and control;
• Cooling system thermal management, control and heat transfer;
• Experimental and predictive approaches to assess different air charge strategies;
• Control strategy development;
• Objective assessment of subjective driveability;
• After-treatment performance assessments;
• Hardware-in-the-loop capability.
