Cornell have a team of experts that understand how important diesel emissions reduction is, not only in promoting a cleaner environment, but also in improving engine performance. Cornell always strive to minimise vehicle downtime while optimising the impact of fuel emissions. The following devices are used to provide effective emission solutions for diesel powered vehicles.

With the complexity of modern diesel powered vehicles a problem can be the result of something relatively simple or much more complex any of the sub-systems, such as air induction systems, exhaust system, emission control devices, diesel fuel injection system, drivetrain components and other sensors and actuators. After you book your vehicle in for a diagnostics service, our customer support team will communicate with you throughout the process to ensure you are kept regularly up to date with progress, with our goal of trying to get your vehicle back on the road as soon as possible.


One of the key devices to reduce the emissions from diesel fueled vehicles is call a Diesel Particulate Filter (DPF) device. The DPF filter, traps particulate matter in its container which it then when full, reduces to ash during regeneration. Regeneration is controlled by the correct driving cycle of the vehicle and its engine management system. Faults that occur with a vehicle can cause the DPF to become blocked or damaged and then regeneration is not possible. At Cornell, an emissions expert will inspect the DPF Diesel Particulate Filter and ensure it is repaired at a high standard.


Selective catalytic reduction (SCR) of NOx service are used as a leading emission solution for diesel powered vehicles. They are made up of nitrogen compounds, such as ammonia or urea. Since mid-2000s, urea-SCR technology has been also adopted for mobile diesel engines and has been widely used in all types of mobile diesel engines. The emission solutions experts at Cornell will inspect the SCR and provide a high level of servicing from the diagnostics through to the repair.
