Measurement principle. The emissions to be measured from the exhaust of the engine include the gaseous components (carbon monoxide, total hydrocarbons for diesel and type 3B dual-fuel engines on the ESC test only; non-methane hydrocarbons for diesel, dual-fuel and gas engines on the ETC test only; methane for gas and dual-fuel engines on the ETC test only and oxides of nitrogen), the particulates (diesel and dual-fuel engines only) and smoke (diesel and dual-fuel engines on the ELR test only). Additionally, carbon dioxide is often used as a tracer gas for determining the dilution ratio of partial and full flow dilution systems. Good engineering practice recommends the general measurement of carbon dioxide as an excellent tool for the detection of measurement problems during the test run." Paragraph 2.1.1. amend to read:
