Prevost Bus SCR/DEF Delete

What is Prevost & Volvo Bus SCR/DEF Delete?

Prevost and Volvo bus SCR/DEF delete targets the Selective Catalytic Reduction (SCR) and Diesel Exhaust Fluid (DEF) systems. SCR systems rely on DEF to catalyze the reduction of nitrogen oxides (NOx) in the exhaust. SCR/DEF delete systems target the removal of DEF, SCR, or both. The removal of SCR/DEF systems directly impacts the maintenance and operational costs of the bus systems. However, it alters the emissions controls, negatively impacting the environmental compliance of the diesel engines and the regulatory aspects.

When we talk about Prevost Bus SCR/DEF Delete, we talk about the actions taken to either bypass or remove the SCR (Selective Catalytic Reduction) system on the Prevost buses. Using a special liquid called diesel exhaust fluid or AdBlue, will help cut down on the negative emissions. That said, some owners of Prevost Buses choose to engage in SCR delete service to improve efficiency and cut down costs.

Volvo Bus SCR/DEF Delete

Similarly, Volvo Bus SCR/DEF Delete involves the bypassing or removal of the SCR system in Volvo buses. This system also uses DEF to minimize harmful emissions, but some Volvo Bus owners choose SCR delete to improve performance and lower maintenance expenses.

Advantages of using Mochester App (M4 App)

Mochester App, created by DrunkLab LLC, is one of the top solutions for truck tuning, focusing on SCR, DEF, DPF, and EGR system deletions. You can fine-tune the settings for buses and trucks to remarkable standards to suit individual needs. Users can always obtain perfect tuning to fit their individual vehicle needs when they connect the vehicle to a laptop with the M4 App using a diagnostic adapter.

Prevost and Volvo buses SCR/DEF Delete Advantages and Disadvantages

Advantages:

• Increased Fuel Efficiency: Removing the SCR system makes it possible to optimize fuel consumption, resulting in improved fuel economy.
• More Powerful Engine: You can have a more powerful engine performance after the SCR System Removal.
• Lower Maintenance Costs: Without DEF and its parts, you can save a great amount on maintenance.
• No Costs for DEF and Storage: Without the SCR System, you also don't need to buy and store DEF, which eliminates those costs.
• No Problems with Poor DEF: You will not have the problems associated with poor DEF.
• No More Guaranteed Starting Problems: You will not have starting problems due to low DEF.
• No More Problems with SCR in Cold Weather: You will not have the problems with SCR in cold weather.

Disadvantages:

• Increased NOx Emissions: Taking out the SCR system leads to an increase in nitrogen oxide emissions which pollutes the environment even more.

Conclusion

Although the Prevost and Volvo Bus SCR/DEF Delete has different advantages especially on performance and savings, you cannot disregard the downsides like the impact on the environment.

FAQ

How to tune the Prevost or the Volvo Bus via the M4 App?

What is Prevost and Volvo Bus SCR/DEF Delete?

Removing DEF or the SCR system for a Prevost and Volvo Bus is done for performance improvement and to minimize maintenance cost.

What are the advantages of using Mochester App?

Mochester App (M4 App) provides benefits which include better fuel economy, more power, and lower maintenance costs by removing SCR, DEF, DPF, and EGR systems.

How does SCR system work in Prevost and Volvo buses?

SCR (Selective Catalytic Reduction) systems in these buses use DEF (diesel exhaust fluid) or AdBlue to transform toxic emissions into harmless nitrogen and water vapor.

What are the issues with SCR systems?

SCR systems may have DEF issues, cold weather may cause crystallization, there may be issues with the sensors, and they require more maintenance.

How does SCR/DEF Delete affect emissions compliance?

SCR systems should not be deleted because NOx emissions will increase and most regions will be in breach of emissions compliance.
