Diesel-engined Particulate Filtration system Tests On Autos With GPS Logging

The problem is that almost each new filter requires a new design and style simply because of the selection of exhaust techniques and their varying temperature and stress operating levels. In the course of examination drive filter temperature, pressure, motor speed, idle instances, automobile situation and velocity need to be calculated properly and reliably to confirm that the filter satisfies the essential standards. In buy to file the take a look at information customer made a decision to use a information logger in mix with a GPS sensor to record measurement info from the filter in blend of motor vehicle position data.

For this logging software the customer is utilizing TopMessage data logger with 2 modules. The whole technique is mounted in a weather conditions evidence enclosure and the sensors are interfaced to the enclosure by means of special connectors.

For the duration of the examination travel all check knowledge is recorded to the inside memory of the TopMessage data logger. The velocity of the motor (rpm) is recorded by way of a different velocity meter (DAB 500 from AVL) which is delivering TTL pulse output. The pulses are then recorded by the counter and inputs of the DIOT module. maxxforce egr delete is visualised via a mimic interface of the ProfiSignal Fundamental application.

In buy to file the automobile pace and route a specific NEMA driver for a GPS sensor was designed. This driver is interface to the TopMessage by means of serial RS232 port. The GPS details like velocity, course, altitude a individual COM channel is designed and all the knowledge is saved straight in the 1 GB TopMessage data logger memory.

Right after the check drive is concluded, all the data is analysed with the ProfiSignal computer software. It is also achievable to change the GPS info into a KLM file which can be loaded by Google Earth to plot a variety of measurement channels like car velocity, filter temperature or strain of placement or motor pace.

Summary of Rewards:

The customer is making use of now 5 Information Acquisition systems to run the diesel particulate filter tests. The major advantages for them are:

The one GB inside memory gives storage capability for numerous thousand examination push kilometres.
Straightforward to configure ProfiSignal computer software to demonstrate dwell looking through for the duration of the test push.
The interface of the GPS sensor also gave beneficial further information about vehicle speed in mix with motor RPM and particle emission.
The universal analog inputs produced it very straightforward to link the temperature and strain sensors.
The modest and compact size of the data logger of (200x73x118) mm created it quite functional for the installation in a tiny enclosure.
In interior calculation and logic channels where employed to trigger info logging when examination problems are reached.
