Heavy duty engines - Measurement of gaseous emissions from raw exhaust gas and of particulate emissions using partial flow dilution systems under transient test conditions
This International Standard specifies methods for the measurement and evaluation of gaseous and particulate exhaust emissions from heavy-duty engines under transient conditions on a test bed. The procedures it defines can be applied to any transient test cycle that does not require extreme system response times; it can therefore be used as an option to the regulated measurement equipment of certification test cycles — usually CVS-type systems — with the approval of the certification agency [among certification test cycles in place are the European transient cycle (ETC) and the US heavy-duty transient cycle (FTP)]. This International Standard is applicable to heavy-duty engines for commercial vehicles primarily designed for road use, but can also be applied to passenger car engines and to engines used for non-road applications. The test equipment specified in this International Standard can also be used in steady-state test cycles, however, if so, the calculation procedures will need to be replaced by those applicable to the particular test cycle.
