In the last 15 years, diesel engines in passenger cars have evolved rapidly. The combination of performance, fuel consumption, emissions and refinement offered by a modern diesel engine makes it the preferred engine choice in many sectors of the market. The enormous progress made has resulted from technological improvements such as low swirl 4-valve per cylinder, direct injection combustion systems complemented by high pressure common rail fuel systems and high levels of turbocharger boost pressure. The durability and output potential of such engines is strongly linked to the operating temperature of certain key components. Accurate temperature predictions are an essential pre-requisite to the continuing evolution, thus placing emphasis on the need for high quality predictive tools.
