Abstract
The paper describes the results of a major development programme in association with industry on a prototype variable geometry turbocharger turbine coupled to a wide mass flow range compressor, and the matching of this unit to a standard Perkins T 6.354 engine.
The performance target for the turbine was a mass flow turn down ratio of 2:1 and achievement of potential torque back up of 50% at half of rated engine speed.
The results are described under the following headings:
-
1.
TURBINE PERFORMANCE ASSESSMENT - Rig testing in high speed dynamometer for various settings of V.G. device and discussion of experimental results.
-
2.
V.G. TURBOCHARGED ENGINE PERFORMANCE ASSESSMENT.
-
2.1
Steady state performance results.
-
2.2
Transient performance results.
The paper concludes with a discussion of the potential of V.G. turbocharging in commercial applications.
