What is Diesel Emission?
Diesel exhaust comes from engines burning diesel fuel. It is a complex mixture of gases, vapours, liquid aerosols and particulate substances. These substances are the products of combustion.
The main chemical components of diesel exhaust emissions are:
Gases and Vapours
These are mostly the gases found in air like nitrogen, oxygen, water vapour and carbon dioxide. There are also hazardous chemicals like nitrous oxide, nitrogen dioxide, sulphur dioxide and carbon monoxide.
Diesel Particulate Matter (DPM)
Fine particles known as DPM including find carbon particles – hazardous chemicals known as poly aromatic hydrocarbons (PAHs) adhere to the surface of carbon particles. DPM can act like a gas and stay airborne for long periods of time. DOM can penetrate deep into the lungs because of its small size and can eventually cause severe health risks.
Diesel Particulate Filters and Catalytic Purifiers
Diesel Particulate Filters (or DPF’s) and Catalytic Purifiers are one of the solutions widely used in the industry to reduce emissions.
Catalytic Purifiers are used to eliminate and change the gases and vapours via a reaction within the catalyst to make the less harmful in the working environment.
DPF’s are made from either a metallic or ceramic material, which filters harmful soot and particulates out of the exhaust and prevents them from entering the environment.
