A microfocus computed tomography (CT) system from Nikon Metrology is being used by BorgWarner Poland to improve research and development of turbochargers for passenger cars, light trucks, and commercial vehicles. The high-power (450 kV) X-ray equipment is able to penetrate the dense materials used in turbocharger production, allowing the internal material quality of castings to be checked nondestructively, and the integrity of welded assemblies to be inspected.

In addition, dimensional data for specific components is acquired more quickly than is possible with a coordinate measuring machine (CMM), both from external and internal dimensions. 

Euro 6 emissions regulations are due to take effect in Europe in 2014, which will further cut the amount of harmful gases and particulates allowed in a vehicle’s exhaust. In response, engine manufacturers and their suppliers are deploying ever more advanced technology in the design and development of air management systems. The goal is not only to reduce pollution, but to also improve fuel economy and enhance vehicle performance.
