Volvo CE SCR/DEF Delete

What is Volvo CE SCR/DEF delete?

Volvo CE SCR/DEF Delete is a modification that turns off the Selective Catalytic Reduction system and the Diesel Exhaust Fluid (DEF/AdBlue) system in Volvo Construction Equipment. The SCR system uses Diesel Exhaust Fluid (DEF) to minimize nitrogen oxide (NOx) emissions. An SCR/DEF delete provides a modification in the engine control system to turn off SCR-related services to remove the consumption of DEF and to reduce the maintenance job associated with the SCR system.

Diesel engines lead to the pollution of the air with chemicals such as nitrogen oxides (NOx), which damage the atmosphere. Volvo Construction Equipment (CE) uses both SCR (Selective Catalytic Reduction) and DEF (Diesel Exhaust Fluid) systems to combat the emission of NOx. While these systems are meant to help the environment, some people that own these systems investigate SCR/DEF delete options. This guide analyzes the advantages and disadvantages of Volvo CE SCR/DEF delete and the Mochester App tuning.

The extensive line of Volvo CE machinery consists of excavators, articulated haulers, asphalt pavers, wheel loaders, compactors, demolition equipment, mini excavators, pipe layers, backhoe loaders, skid steer loaders, motor graders, crawlers, cold planers, soil compactors, material handlers, tracked pavers, tandem asphalt rollers, compact wheel loaders, and planers.

Utilizing the Mochester App (M4 App)

Using the Mochester 4 App (M4 App) makes it easier than ever to fine-tune Volvo CE equipment. It allows extremely detailed alterations of crucial functions such as SCR/DEF. The app was developed in-house and allows the user to connect their vehicles to a laptop and configure custom settings. With the M4 App, Volvo CE customers can improve performance and efficiency of their excavators, wheel loaders, and articulated haulers.

Advantages and Disadvantages of Volvo CE SCR/DEF Delete

Advantages: 

• Cost Savings: Removing SCR/DEF systems from constructions saves the cost of purchasing DEF fluid for construction equipment such as Asphalt Pavers, Compactors, Skid Steer Loaders, etc.
• Reduced Maintenance: SCR/DEF systems, unlike Backhoe Loaders and Mini Excavators, require regular maintenance and component replacements. Therefore, removing SCR/DEF systems from constructions simplifies maintenance and saves time and money.
• Enhanced Reliability: Volvo CE equipment such as Pipe Layers and Motor Graders will have a lower likelihood of failure or malfunction as a result of removing SCR/DEF systems.
• Simplified Operation: With the absence of SCR/DEF systems, operations become less complex, and even drivers and maintenance of Crawlers and Demolition Equipment will find their work less complex.

Disadvantages: 

• Environmental Impact: If you take away the SCR/DEF systems, the NOx emissions would increase, and that might break the environmental laws and increase air pollution.

Conclusion

Volvo CE’s SCR/DEF delete may save costs and reduce maintenance obligations, but owners should still assess the legal, moral, and ecological consequences. The Mochester App allows you to make tuning adjustments, but you should really think twice before you do SCR/DEF delete changes. By understanding the advantages and disadvantages, Volvo CE owners can make informed decisions to optimize their Excavators, Wheel Loaders, Articulated Haulers, and other Volvo CE machinery.

FAQ

How to tune the Volvo CE via the Mochester App (M4 App)?

Will SCR/DEF delete improve fuel efficiency for Volvo CE equipment?

SCR/DEF delete allows for fuel savings that can be gained from the reduced use of DEF fluid. Fuel savings can also be achieved if SCR/DEF delete allows the engine to operate more efficiently.

What are the advantages for Volvo CE equipment with SCR/DEF delete?

With Volvo CE equipment, eliminating SCR/DEF can be more affordable, and require less regular attention, and increase ease of use.

How does SCR/DEF delete affect emissions for Volvo CE? 

The incomplete removal of SCR/DEF systems can lead to a spike in NOx emissions and hence worsen air quality. It can also breach some emissions standards.

Does the Mochester App (M4 App) have the ability to SCR/DEF delete from a distance?

Yes. The Mochester App provides the ability to remove SCR/DEF deletes remotely from select Volvo CE machines.

Will SCR/DEF delete enhance fuel economy?

Results differ based on the machine and the working conditions. Some operators state they have gained better fuel efficiency with SCR/DEF delete due to better engine operation and without DEF.

What Volvo CE machines get support?

Many types of Volvo CE machines get support. Examples of machines include Volvo CE excavators, wheel loaders, articulated haulers, compactors, pavers, Volvo CE construction machines, etc.
