New procedure for exhaust gas measurement
As technology advances in exhaust gas measuring devices, a change in the procedure for measuring exhaust gas opacity from diesel engines is necessary as part of the recurring assessment in accordance with Section 57a KFG 1967.
New procedure for exhaust gas measurement
Both Directive 2009/40/EC and Directive 2014/45/EU stipulate that diesel engines are accelerated up to the cut-off speed during recurring assessments. Due to the increasing number of engine damages when carrying out the exhaust gas measurement as part of the recurring assessment according to § 57a KFG 1967 for diesel vehicles and the resulting considerable damage, efforts were made to measure the opacity in accordance with the above-mentioned. Guidelines to be carried out in a more gentle manner on the engine lead to a change in the prescribed procedure.
Tests have shown that even at significantly lower speed ranges, higher exhaust gas emissions occur than at the limited speed. The respective maximum values occur at the latest when the speed at which the nominal power is achieved is reached. Taking this knowledge into account, a new specification for the test speed was developed. Andreas Westermeyer from the Federal Guild Group Metal-Electro-Sanitary-Mechatronics-Vehicle Technology in the Austrian Chamber of Commerce provides information about the details of the new procedure.
