Diesel Engine Exhaust

Description

– Diesel engine exhaust is a complex mixture of gases and particulate matter (PM) produced when diesel fuel is burned in engines.
– It contains thousands of chemicals, including known carcinogens and other harmful substances, and is a significant contributor to air pollution.

Key Features:
Components:
Gases:
Diesel exhaust includes gases like carbon dioxide, carbon monoxide, nitrogen oxides, and unburned hydrocarbons.
Particulate Matter (PM):
This is often referred to as “soot” and is a major component of diesel exhaust. It consists of tiny solid particles, primarily elemental carbon (EC), with organic carbon (OC) compounds adhered to their surfaces.
Organic Compounds:
Diesel exhaust contains a wide range of organic compounds, including polycyclic aromatic hydrocarbons (PAHs) (some of which are known carcinogens).
Other Pollutants:
It can also contain other harmful substances like sulfur oxides and metals.
