MDEP Highlights

April 12, 2010

Today’s MDEP Highlight demonstrates the capabilities of the MDEP evaluation equipment.  In the example evaluation report below obvious wavy lines are visible in several portions of the MIR 120 Second 5-Gas Transient Procedure.  These wavy lines represent the engine revving up and down during idle.  In many cases this type of engine behavior may not be noticeable to an observer yet the MDEP equipment plainly records the small changes in engine combustion.  In this specific case the engine does not idle steadily but has a small variance caused by the engines governor.

The capability of the MDEP equipment to pick up small changes in combustion, such as these, is a powerful tool that is used to identify and diagnose even the smallest changes and differences in an engines combustion.  The MDEP equipments precision is also used to ensure that every MDEP evaluation is performed correctly by each technician in the field.  If the MDEP procedure is not followed correctly the MIR 120 Second 5-Gas results will quickly show any deviations from the standard evaluation procedures ensuring that all MDEP results meet the standard.
