Turbocharger performance qualification method and apparatus
First Claim
Patent Images
1. A method for qualifying turbocharger performance, comprising the steps of:
- operating a turbocharger at a test condition;
acquiring a set of date from a set of operating parameters of the turbocharger at the test condition;
comparing the set of data to a set of acceptable operating ranges;
determining whether the set of data falls within the acceptable operating ranges;
qualifying the turbocharger based on an outcome of the determination;
wherein the determination step further includes the steps of;
plotting the set of data on a graph;
defining a rectangular area on the graph to represent the acceptable operating ranges; and
determining whether data points on the graph fall within the rectangular area on the graph.

Abstract
A method for qualifying turbocharger performance includes the step of operating a turbocharger at a single test condition (402). A set of data may be acquired from a set of operating parameters of the turbocharger (404) operating at the test condition. The set of data acquired may be compared to a set of operating ranges (406) that are deemed acceptable, and a determination may be made as to whether the set of data falls within the acceptable operating ranges (408). Performance of the turbocharger may then be qualified (412, 414) based on an outcome of the determination (410).

3. A method of testing turbochargers, comprising the steps of:
-
operating a turbocharger at a test condition as part of an engine system; monitoring a set of inputs to the system that includes a fuel consumption rate of the engine system; monitoring a set of outputs from the system that includes a compressor outlet pressure of the turbocharger; comparing the set of outputs to a set of respective acceptable ranges; finding a performance of the turbocharger acceptable at times when the set of outputs is within the set of respective acceptable ranges. - View Dependent Claims (4, 5)

6. A test station for qualifying turbocharger performance, comprising:
-
a test fixture having a turbocharger mounting apparatus attached thereon; an electronic controller associated therewith; a plurality of sensors that are disposed to measure operating parameters of the test station and are operably connected to the test station; a fluid pump arranged and constructed to fluidly connect to a turbocharger at times when the turbocharger is connected to the test fixture with the mounting apparatus, such that a fluid pump outlet is connected to a turbine inlet passage. - View Dependent Claims (7, 8, 9, 10, 11, 12)
