Optimising Emission Control with Catalysts and Filter Substrates by Dinex

Increasingly stringent noxious emissions standards all over the world are forcing manufacturers of truck exhaust system parts to evolve. Dinex is one such company, boasting an impressive record when it comes to substrate filter technology and exhaust after-treatment systems. In this article, we’ll look at the importance of emission control and some of Dinex’s innovative technology.


Why is emission control important?

Vehicle exhausts produce noxious emissions including carbon monoxide, hydrocarbons, nitrogen oxides and other particulates. These emissions are harmful to the environment and significantly reduce air quality. As such, there are standards in place to control heavy vehicle emissions.

Operators must adhere to noxious emissions standards, however, this is nothing new. Standards have been in place since the 1970s, but with a greater focus on the environment, these levels have been tightened in recent years.


What are the current emissions standards?

Australia and New Zealand currently adopt the emissions standards known as Euro V, with slight adjustments to suit the local regulatory environment. Governance comes under the standard ADR80/03, which covers relevant components for European trucks, but Japanese and Amercian truck components that meet equivalent Japanese and US standards will also comply.

From 1 November 2024, a new standard called ADR 80/04 will be phased in, ased on the Euro VI standard. Equivalent Japanese and US standards will still be recognised, however the precise details of ADR 80/04 are still being worked on.

Ultimately, this means that manufacturers of truck parts must reach higher standards when it comes to exhaust after-treatment and other emissions control measures.


Dinex substrates and filters

Dinex is a Danish company formed in 1982, based on a business model of creating spare parts for heavy vehicle exhaust systems. Today, they’re a global company with over 2,000 employees and a presence in three continents.

Dinex offers a range of substrates and filters for heavy vehicles. Specifically, Dinex’s silicon carbide diesel particulate filters are designed to trap up to 95% of particulate matter in the exhaust and reduce the amount of particulates by up to 99%.

Heavy vehicle catalysts

Dinex also specialises in catalytic technology and offers a wide range of solutions for different vehicle types. These catalytic coatings are applied to filters and convert harmful, noxious emissions into nitrogen and water.

Some of the different types of after-treatment catalysts on offer in Dinex truck exhaust systems include:

· Diesel Oxidation catalyst (DOC)
· Diesel particulate Filter Coating (C-DPF)
· Selective Catalytic Reduction (SCR)
· SCR on DPF
· Three-way catalysts (TWC)
· Methane Oxidation Catalyst (MOC)

Understanding what you need before purchasing truck and trailer parts is extremely important, especially regarding emissions control. Different types of exhaust after-treatment technologies will only reduce noxious emissions by certain levels. The current emissions standard in Australia and New Zealand is ADR 80/03, based on the Euro V standards, so the filters, substrates and catalysts you install must also meet these standards.
