Diesel generator emissions
Date posted: 17th September 2020
The exhaust of a diesel engine contains by products from combustion. For environmental safety, a number of these emissions are monitored, but not all applications require compliance with emission regulations.
What emissions does a diesel generator produce?
- Nitrogen oxide (NOx): occurs naturally as a result of bacterial process, biological growth, decay, lightning, forest fires and burning of fossil fuels; colourless non-toxic gas, often referred to as laughing gas
- Hydrocarbons (HC): organic chemical compounds that consist entirely of carbon and hydrogen; they range from simple molecules such as methane to polymers such as polystyrene
- Carbon monoxide (CO): colourless, odourless, toxic gas produced from the incomplete burning of fossil fuels
- Particulate matter (PM): the sum of all solid and liquid particles suspended in the air
How are you using your generator?
For many applications that utilise diesel generator sets, it does not have to comply with any emission requirements when:
- Unlimited operation for emergency power supply on standby mode
- Non-emergency operation of up to 100 hours per year
Major power source: the generator complies with emissions regulations. All major engine manufacturers publish individual emission charts which reflect the EPA tier each engine is certified for.
We have developed low emission diesel generators that can meet Tier 3, Tier 4 Final, and EU Stage V regulations. They are widely used in those places where there are strict requirements around pollution.
