What does DPF do to a diesel particulate filter?
What does DPF do to a diesel particulate filter?
The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. The collected diesel soot particles are burnt off at high temperatures, which results in an “ ash-like ” after product.
How are particulate filters used to reduce emissions?
In order to reduce emissions from diesel vehicles, diesel particulate filters capture and store exhaust soot, which must be periodically burned off to regenerate the filter.
What happens when a particulate filter is blocked?
When the computer detects that the filter is becoming blocked, it will raise the temperature of the exhaust gases to start the regeneration process, which will then take about 10 to 15 minutes to complete. During this time it’s likely you’ll notice that if your car has an engine stop-start system, it will deactivate.
How often should I clear my diesel particulate filter?
To make sure that the regeneration takes place, most manufacturers suggest that every few hundred miles, the car is driven for a period of more than 15 minutes at a consistent speed in excess of 40mph. Doing this should clear the filter. If the DPF can’t regenerate passively, the car’s onboard computer will have…
Can a performance modification damage a diesel particulate filter?
Performance modifications can damage a diesel particulate filter, as can using low-quality fuel and even running the car frequently on a low fuel level as the car may avoid DPF regeneration in order to save fuel. How do I maintain a diesel particulate filter?
What’s the life of a diesel particulate filter?
The lifespan of a diesel particulate filter varies based on the application. For example, the Cummins ISX15 engine’s filter has an interval for cleaning up to 400,000 to 600,000 miles—although it will need to regenerate before hitting the 400,000 mile mark. DPFs may fail sooner if they are not well maintained.
Why is the diesel particulate filter a ticking time bomb?
The Diesel Particulate Filter (DPF) is best described as the “ticking time bomb” in most modern diesels. Similar to EGR problems, the DPF can become clogged up from city driving where the car does not get up to temperature. The whole reason the Diesel Particulate Filter came along was to clean up the diesel car image (Euro 5 Emissions, 2009).
In order to reduce emissions from diesel vehicles, diesel particulate filters capture and store exhaust soot, which must be periodically burned off to regenerate the filter.
