Bringing the HEAT on COOLING technologies

Electronic controls, variable-speed fans cool engines, heat aftertreatment systems.

Thermal management continues to become more complex as engineers strive to cool engines while generating enough heat to burn away unwanted emissions matter. Ever smarter electronic controls are helping design teams provide optimal performance and long engine life while meeting emissions requirements.

More demanding customers, expanding regulations and growing sophistication at all levels of system design are combining to make thermal management a multifaceted design challenge. Mechanical elements remain a mainstay in the battle to remove heat. But as in many aspects of vehicle design, electronic control units (ECUs) are gaining more of a role.
