The Importance of Aftertreatment Parts

Improve Performance

As diesel engines have become increasingly popular in recent years, the demand for high-quality aftertreatment parts has also grown. Aftertreatment parts are essential for reducing harmful emissions and ensuring diesel engines run efficiently and effectively. At DPF Alternatives, we are proud to specialize in local DPF parts. We offer a wide range of products that can help to improve the performance of diesel engines.

Our DPF Products & More

Diesel particulate filters (DPFs) are designed to reduce harmful emissions by capturing and removing particulate matter (PM) emissions produced by the combustion process from diesel engine exhaust. If you are searching for DPF replacement, DPF Alternatives offers high-quality restoration and repair services to keep your DPF running smoothly.

DPF bungs are a critical component of DPF systems, designed to temporarily seal the DPF to the exhaust system during maintenance or repairs or to permanently seal off unused ports on the DPF to prevent exhaust leaks.

DPF clamps are specialized clamps used to secure the DPF to the exhaust system, ensuring it remains in place during operation. They are typically made of high-quality stainless steel to tolerate high temperatures. They come in various sizes and types to prevent leaks and maintain proper emissions control.

DPF gaskets seal the joints between the DPF and the exhaust system, preventing leaks and ensuring exhaust gasses flow through the DPF as intended. They are typically made of heat-resistant materials such as graphite or metal and are designed to withstand the harsh operating conditions of diesel engines.

DPF sensors monitor the performance of the DPF system, providing feedback to the engine control unit (ECU) and alerting the driver if there are any issues. They are typically located upstream and downstream of the DPF and measure parameters such as exhaust pressure, temperature, and flow rate.

Diesel oxidation catalysts (DOCs) are exhaust aftertreatment devices that reduce emissions of harmful pollutants from diesel engines. This technology uses a chemical reaction to convert harmful gasses such as carbon monoxide (CO) and hydrocarbons (HC) into less harmful gasses such as carbon dioxide (CO2) and water vapor (H2O). It can also oxidize some of the exhaust stream's nitrogen oxide (NOx).

Selective catalyst reduction (SCR) is an aftertreatment technology that reduces nitrogen oxide (NOx) emissions from diesel engines. It involves injecting a liquid reductant into the exhaust stream before it enters a catalytic converter. The liquid then reacts with the NOx in the exhaust to convert it into harmless nitrogen gas and water vapor.

Exhaust gas recirculation (EGR) is a technology that reduces NOx emissions from diesel engines. EGR systems work by recirculating a portion of the exhaust gasses back into the engine, reducing the amount of oxygen available for combustion and lowering the combustion temperature. EGR coolers cool the exhaust.

Diesel Particulate Filter (DPF) Replacement

When you’re operating a diesel engine vehicle yourself or you’re in an industry surrounded by diesel engines, it’s important to understand how they operate and the special services they require. One essential component is the diesel particulate filter or DPF. Choose the professionals who have the expertise to handle your system correctly.

DPF Alternatives DPF Bungs

DPF Bungs

DPF filter bungs are small stainless steel pieces of metal that hold your vehicle’s sensors in place. They vary in size, shape and threading, and keeping your bungs in good condition can significantly extend the life of your DPF system.

DPF Clamps

DPF clamps are pieces of metal that ensure the filter connects to the exhaust system and doesn’t wiggle loose. They ensure that the DPF works the way it is supposed to. If you don’t pay attention to your DPF filter clamps, then you risk losing a lot more than a simple aftertreatment part.

DPF Sensors

DPF sensors are crucial for evaluating and fine-tuning a vehicle's Diesel Particulate Filter (DPF) system. By relaying essential information to the engine control unit (ECU), these sensors facilitate early detection of problems like clogs, suboptimal combustion, and unusual flow rates. DPF Alternatives delivers comprehensive DPF sensor services, ensuring your fleet operates at its best while staying compliant with environmental regulations.

Yes, we have new aftermarket DPF’s for sale if yours is cracked, damaged or can not be restored.

The pricing range between these two options will be very significant. A new replacement DPF cost will depend on what kind of vehicle you have however it will most likely cost you thousands of dollars.

If the truck is doing multiple regens (4+ per week), there is a high chance your DOC needs replacing. If you notice your vehicle doing multiple regenerations in a short period of time, this usually means precious metals are no longer working.

Removing the DPF from your aftertreatment system can be a legal issue depending on where you are from. In some Canadian provinces, it is mandatory to have a DPF filter as a part of your aftertreatment system. Having your filters removed or “deleted” could lead to unexpected charges.
