AS 3584.4:2021 pdf download.Diesel engine systems for underground coal mines Part 4: Emissions.

1.3.1

after all treatment

test location for gaseous and particulate pollutants after all devices that are designed to modify the constituents of the exhaust

Note ito entry: Devices installed within the exhaust system that are designed to modify the constituents of the exhaust emissions

may include a diesel oxidization catalyst (DOC), selective catalytic reducer (SCR), continuously regenerating trap (CRT). fuel

based catalyst (FBC), diesel parUculate filter (DPF). trap systems, a three way catalyst, or other systems and devices.

1.3.2

before all treatment

test location for gaseous and particulate pollutants after the DES exhaust valves and as close to as is practical, and before, all devices that are designed to modify the constituents of the exhaust gasses

Note 1 to entry: Devices installed within the DES that are designed to modify the constituents of the exhaust emissions exclude

exhaust gas re-circulation (EGR), variable geometry turbochargers, shaped injection systems and like systems or devices that are

integral to the original engine design.

1.3.3

cold start

first start after the engine has soaked to room temperature and the engine coolant and oil temperatures have stabilized between

10 °C and 30 °C

Note 1 to entry: Measurements for this includes all after treatment systems and all auxiliary engine control devices.

1.3.4

elemental carbon

EC

agglomeration of small carbon particles with a graphitic structure

Note 1 to entry: A major component of diesel particulate matter. Provides a site for the deposition of organic compounds and other condensable products of combustion.
