This software package was developed and continues to be upgraded because of customers requests to increase quality and protect the integrity of the testing being performed on catalytic converters. To this end, our customers which use the EMAS II and the catalyst aging software package, demanded functionality which meets their goals of increased quality and confidence in the data being produced.

Testing is an expensive proposition.  The time and effort involved must be protected by making sure that the specifications and results of the test are carefully monitored and adhered to. Tests which do not meet specifications, or are not reproducible are of little value. As a result we have developed this package for our customers to use so that quality data in a timely manner can be recorded, analyzed, and used to assure that proper testing is being conducted.

This package records, analyses,  summarizes, and monitors the following signals: 

4 Thermocouples mounted in the Inlet, and Midbed of a catalytic converter.

4 EGO signals Pre and Post

12 Injector Pulse widths

1 AFR

These signals along with some common engine signals such as Throttle position, Vacuum, and Battery Voltage are recorded and summarized on the fly. The data can be viewed of a network quickly and easily. All data is recorded at 10Hz, and is stored while simultaneously the data is analyzed and summarized to produce key pieces of information including histograms, average cycle morphology, out of spec reports, and modal analysis.

Here are samples of the results which are produced.

These graphs represent the average AFR  and the average temperature which the catalyst was exposed to during a test.

These pictures below are histograms which are produced on the fly of the temperatures the catalyst is experiencing.

This picture is an example of modal analysis. The aging test is usually comprised of a repetitive cycle which is composed of many steps. In modal analysis, each step of mode is sampled and analyzed, then the results of all the common steps or modes are plotted verses each aging cycle number. The graph below indicates the temperature being experience by the Inlet of a catalyst during each of its "Mode 1".

Modal Analysis is also performed on all the temperature inputs and the Air Fuel Ratio signal.

Additionally, all the data is available for viewing at a touch of a button.
