Air filters used in vehicles are the engine air filters, cabin air filters, car exhaust filters, and diesel particulate filters (DPF). Baghouse filters are pollution control equipment that removes particulates and pollutants in flue gases from process equipment before releasing them into the atmospher...
As a result, the infamous diesel particulate filter (DPF) came into being in 2007, and diesel exhaust fluid (DEF) was introduced in 2010 into the exhaust stream to reduce particulates and NOx. While this change was a benefit to the environment, the introduction of bo...
To put 0.3 microns in perspective, it's worth remembering that a typical human hair is roughly 50–150 microns in diameter, so a HEPA filter is trapping dust several hundred times thinner. The sooty particulates that spew from diesel car exhausts are generally described as coarse PM10 (...
As a result, the infamous diesel particulate filter (DPF) came into being in 2007, and diesel exhaust fluid (DEF) was introduced in 2010 into the exhaust stream to reduce particulates and NOx. While this change was a benefit to the environment, the introduction of both brought tales of woe...
How does an aftertreatment system work? The harmful emission gases in the exhaust stream move from the exhaust side of the turbo to the aftertreatment system (outlined in red). The Cummins Particulate Filter contains the Diesel Particulate Filter (DPF) which collects and oxidizes carbon to remove...
On the other hand, when the exhaust temperature is in transit in each confirmation stage of each target temperature, temperature confirmation at the in-transit target temperature is repeated for a predetermined time, and when the exhaust temperature does not reach the in-transit target temperature ...
1. Diesel particulate filter (DPF) replacement– When replacing a DPF, certain OEMs can require engine ECU learned data be reset, the replacement component serial number programmed into the ECU, as well as providing an internet-based update of the new part number to an OE’s central syst...
Find out more about how our diesel engine oils help to meet EURO VI regulations! Contact us How does an after treatment device work? An ATD uses regeneration to burn off collected particulate matter. For a successful regeneration the exhaust must be kept at high temperatures for a long time....
For example, Puff says we can predict when we’ll need to clean or change a diesel particulate filter or predict certain injector failures by measuring how much fuel goes through an engine under what duty cycles. “On the other hand, some failures are related to metallurgy or manufacturing or...
Dangerous - Your car has issues that pose a direct and immediate risk to road safety or have a serious impact on the environment. You are not permitted to drive away. Diesel emissions The latest test includes stricter limits for emissions from diesel cars with a diesel particulate filter (DP...
