Measurement of exhaust emissions during type approval tests, e.g. WHTC, WHSC, NTE, NRSC, NRTC

Emission measurements for homologation tests are carried out on the engine dyno in accordance with the latest international standards for heavy duty engines. Uniform WH (World Harmonized) tests are carried out for on-road applications, both dynamic (WHTC) and stationary (WHSC), whose results are respected in most global markets. There are also tests for off-road and marine applications like NRSC, NRTC and NTE, as required by the EPA.
