Hot air entering engine can create a higher combustion temperature, which creates a greater nitrogen oxide formation and increases thermal load on the engine and related components. Charge air cooler act as a cooling interface, which transforms hot air coming from a turbocharger or a supercharger to cool air entering combustion engine. CACs also contribute towards a reduction in turbo lag and an improvement in engine volumetric efficiency with lower engine displacement.
Europe is expected to remain the largest automotive charge air cooler market during the forecast period, owing to the high penetration of diesel engine vehicles coupled with a greater penetration of turbochargers to address the strict emission norms of European Commission. North America, another considerable region, is also likely to generate a healthy demand for charge air cooler in the coming years, primarily propelled by the USA and Mexico.
