The Free Measurement program allows the DGA 5000 to be used as a
diagnostic tool for the investigation of the fuel, ignition and emission
control systems of a vehicle without applying the limits and procedures
specified in any local, national or international test. By operating the
vehicle under varying conditions (if necessary on a chassis
dynanometer) it is possible to:
- Identify emission failure areas.
- Reduce emissions in general.
- Locate/correct drivability problems.
The drivability and emissions symptoms (or combinations of symptoms)
that can be addressed include:
- Engine will not crank.
- Engine will crank but will not start.
- Engine is hard to start.
- Malfunction lamp is on.
- Engine stalls.
- Engine shows hesitation, sag, stumble and/or lack of power, is
sluggish or feels spongy.
- Engine surge.
- Engine misses or cuts out.
- Engine backfires.
- Excessive engine noise.
- Excessive emissions or a failed emission test.
- Poor fuel economy.
- Incorrect idle.
- Engine jumps or jerks.
- Excessive exhaust odor.
- Excessive exhaust smoke.
- Fuel odor and/or dieseling or run-on.
