Diesel exhaust purifiers — what are they, and why do we need them?

The world is working hard to reduce emissions, but diesel engines still have their place, especially in heavy industry and transportation. 

Thanks to their power and efficiency, diesel engines often outperform petrol and electric options for heavy goods vehicles. However, this comes with a big downside—they emit harmful gases that can seriously affect our health and the environment.

The health hazards of diesel emissions

Diesel engines release a number of harmful gases, including nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM). These emissions can worsen breathing conditions like asthma, bronchitis, and pneumonia. Long-term exposure can lead to even more severe health problems, like lung cancer and heart disease. In confined spaces like tunnels, carbon monoxide can be deadly as it’s odourless and colourless, making it hard to detect without proper sensors.

Environmental impact

Diesel emissions are particularly harmful in cities. Particulate matter from diesel exhaust significantly contributes to smog, which deteriorates air quality and harms the environment. NOx emissions also play a role by forming ground-level ozone, a major component of smog, which can cause respiratory issues for both humans and animals.

The need for diesel exhaust purifiers

To address the health and environmental problems caused by diesel emissions, we need to filter out the harmful gases. That’s where diesel exhaust purifiers come in. These devices are designed to reduce or eliminate dangerous emissions from diesel engines, making them safer for people and the planet.

How diesel exhaust purifiers work

Diesel exhaust purifiers use catalytic converters to break down harmful gases into less harmful ones.

The key component inside the catalytic converter is the substrate. This is a ceramic or metallic structure coated with metals like platinum, palladium, and rhodium. When exhaust gases pass through the substrate, these metals catalyse a reaction that converts harmful gases like CO and NOx into less harmful substances like carbon dioxide (CO2) and nitrogen (N2).

To protect the substrate and make it durable, it’s usually encased in a high-grade stainless steel housing.

At IAC Acoustics Australia, we offer a range of exhaust purifiers that can be integrated into new systems or retrofitted into existing ones. These purifiers are specifically designed for diesel and CNG (Compressed Natural Gas) engines, providing a reliable and cost-effective way to reduce emissions.

Benefits of IAC Acoustics’ exhaust purifiers

Not all exhaust purifiers are the same. It’s crucial to choose a reliable product from a reputable company. IAC Acoustics provides data to prove our purifiers meet strict environmental and safety standards, helping you keep your operations compliant and safe.

Our exhaust purifiers are also built to last. The housings are made from high-grade stainless steel and can handle the changing temperatures caused by the engine running. Plus, these purifiers help reduce noise, providing a complete solution for cleaner and quieter engine operation.

Summary

Diesel exhaust purifiers are essential for reducing harmful emissions, protecting health, and safeguarding the environment. If your business uses diesel or CNG-powered machinery, investing in quality exhaust purifiers is a smart move.
