An experimental thermal survey of a turbocharger was performed in an engine test cell using IR thermography. The emissivity coefficients housings were specified furnace and camera. It shown that the turbine, compressor, bearing are 0.92, 0.65, 0.74, respectively. In addition, thermocouples mounted on housing to validate temperature camera while running cell. To compare data thermocouple with fr...

Turbocharging is becoming a key technology for both Spark Ignition (SI) and diesel automotive engines. As regards gasoline engines, turbocharging can help to reduce CO2 emissions when used in conjunction with other technologies, such as engine downsizing, direct injection and variable valve actuation, all managed on the basis of appropriate control strategies. However, the successful applicatio...
