High Volume Production of Ball Bearing Turbochargers

Author: K-H Bauer, C.Balis, D.Paja, P.Davies, D.Marsal (Honeywell Turbo Technologies)

Recent developments at Honeywell have introduced Ball Bearing technology to passenger car diesel. The new “low-friction” turbo, which runs on two rows of ceramic balls, has much lower mechanical losses and hence higher turbo efficiency. The result is an improvement in transient response of between 20-70 percent dependant oil temperature and 2 percent improvement in fuel economy in standard test cycles. The 3.0L V6 diesel application in Europe is an example of the true potential of ball bearing technology.
