Detailed Description
Following is a more detailed description of various concepts related to, and embodiments of, methods, apparatus, and systems for testing a doser of an exhaust gas after-treatment system of an internal combustion engine system (such as a doser for dosing a reducing agent to the exhaust gas) and/or for testing a sensor of an exhaust gas after-treatment system of an internal combustion engine system (such as a sensor for determining a property of the exhaust gas) or for determining an operating characteristic of an internal combustion engine system. The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways, as the described concepts are not limited to any particular implementation. Examples of specific embodiments and applications are provided primarily for illustrative purposes.
I. Overview
Internal combustion engine systems (e.g., diesel internal combustion engine systems, etc.) produce exhaust gas that is typically treated by a doser (e.g., dosing module, etc.) within an exhaust aftertreatment system. Parameters of the exhaust gas are typically measured by exhaust gas aftertreatment system sensors, and operating characteristics of the internal combustion engine system are typically measured by internal combustion engine system sensors. Depending on the configuration of the internal combustion engine system, the brand and configuration of the doser, the exhaust gas aftertreatment system sensor, and/or the internal combustion engine system sensor may vary. For example, UA2 (e.g., air-assisted dispensers, etc.), UL2 (e.g., liquid-only dispensers, etc.), and UL2.2 are differently configured dispensers, while Bosch and Albonair are differently branded dispensers. One example of a dispenser configuration and brand is a Bosch Denoxtronic dispenser (e.g., a Bosch Denoxtronic 2.2 dispenser, etc.). Different connectors may be used for each different brand or configuration of dosers, exhaust aftertreatment system sensors, and internal combustion engine system sensors. Accordingly, equipment that interfaces with the doser, the exhaust gas after-treatment system sensor, and/or the internal combustion engine system sensor may require the doser, the exhaust gas after-treatment system sensor, and/or the internal combustion engine system sensor to be specific to a particular brand or configuration. Further, each brand and configuration of dosers, exhaust aftertreatment system sensors, and internal combustion engine system sensors may have a different electrical system configuration. For example, the doser may have a 12 volt electrical system configuration (e.g., the doser is configured to be operable only when connected to a 12 volt power source, etc.) or a 24 volt electrical system configuration (e.g., the doser is configured to be operable only when connected to a 24 volt power source, etc.).
Currently, testing of dosers, exhaust gas after-treatment system sensors, and internal combustion engine system sensors is not typically performed with the dosers, exhaust gas after-treatment system sensors, or internal combustion engine system sensors disposed (e.g., installed, etc.) in the exhaust gas after-treatment system and/or internal combustion engine system (e.g., "on-site," etc.). In contrast, dosers, exhaust gas after-treatment system sensors, and internal combustion engine system sensors are typically removed from the exhaust gas after-treatment system and/or internal combustion engine system and shipped to a service center for testing. This process results in delays in the operation of the exhaust aftertreatment system (e.g., downtime, etc.) and the operation of the internal combustion engine system, and results in significant transportation costs.
Because different connectors are used for different brands or configurations of dosers, exhaust gas after treatment system sensors, and internal combustion engine system sensors, test equipment is typically dedicated to a particular brand or configuration of dosers, exhaust gas after treatment system sensors, and/or internal combustion engine system sensors. The service center tests a plurality of dosers, exhaust gas aftertreatment system sensors, and internal combustion engine system sensors, and generally does not limit testing to a particular brand or configuration of dosers, exhaust gas aftertreatment system sensors, or internal combustion engine system sensors. Accordingly, multiple pieces of test equipment are often required to facilitate testing of multiple dosers, exhaust gas aftertreatment system sensors, and/or internal combustion engine system sensors. The procurement and maintenance of multiple pieces of test equipment can be both expensive and inconvenient for a service center.
Embodiments herein relate to a device capable of testing a doser, an exhaust gas aftertreatment system sensor, an internal combustion engine system sensor, NOxSensor and temperature sensor multi-dose dispensers and multi-sensor test systems. The multi-doser and multi-sensor testing system includes a common doser harness having a plurality of dedicated doser connectors, each connector configured to connect to a different brand or differently configured doser. The multi-doser and multi-sensor testing system further comprises a test system having a plurality of dedicated rejectsA common exhaust aftertreatment system sensor harness of exhaust aftertreatment system sensor connectors, each connector configured to connect to a different brand or different configuration of exhaust aftertreatment system sensor. The multi-doser and multi-sensor testing system further includes a common engine system sensor harness having a plurality of dedicated engine system sensor connectors, each connector configured to connect to a different brand or different configuration of engine system sensors. In this manner, the multi-dispenser and multi-sensor testing system may be used in a variety of applications that may require testing of different brands or configurations of dispensers, exhaust gas aftertreatment system sensors, and/or internal combustion engine system sensors.
In some embodiments, the multi-doser and multi-sensor test system is only capable of testing dosers and not exhaust gas aftertreatment system sensors or internal combustion engine system sensors. In other embodiments, the multi-doser and multi-sensor test system is only capable of testing exhaust gas aftertreatment system sensors or internal combustion engine system sensors, but not the doser. In other embodiments, the multi-doser and multi-sensor test system is capable of testing only one of the doser, exhaust gas after treatment system sensor, or internal combustion engine system sensor, and is not capable of testing the other of the doser, exhaust gas after treatment system sensor, or internal combustion engine system sensor.

If any fault codes are detected in block 334, the testing process 300 continues in block 336 with a fault indication (e.g., "test failed," etc.) displayed to the user by the graphical user interface device 186. However, if a fault code is not detected in block 334, the test process 300 continues in block 338 with a pass indication being displayed by the graphical user interface device 186 (e.g., "test passed," etc.).
The test procedure 300 continues at block 340 with the processing circuitry 114 determining whether a print report is required. For example, the graphical user interface device 186 may query the user whether the report needs to be printed and receive input from the user determining that the report does not need to be printed.
If a print report is required, the test process 300 continues in block 342 with the graphical user interface device 186 displaying the requested doser 102, exhaust gas after-treatment system sensor 105, internal combustion engine system sensor 107, NOxA serial number and/or a part number of the sensor 104 and/or the temperature sensor 106, and subsequently receiving the doser 102, the exhaust gas aftertreatment system sensor 105, the internal combustion engine system sensor 107, the NO from the user by the graphical user interface device 186xSerial number and/or part number of the sensor 104 and/or the temperature sensor 106.

The printing may instruct the report to be displayed on the graphical user interface device 186, the report to be transmitted by the controller 110 to an external device (e.g., a printer, a mobile device, etc.), or the report to be saved in the memory 118.
After the report is printed, the testing process 300 continues in block 346 with the graphical user interface device 186 displaying a termination message (e.g., "test has completed — shut down system to test again", etc.). If processing circuitry 114 determines in block 340 that a print report is not required, then testing process 300 continues with the direct display of a termination message by graphical user interface device 186 (i.e., skipping blocks 342 and 344, etc.).
