This process is crucial for meeting modern emissions standards.

How DEF Reduces Emissions

1. Injection Process: DEF is injected into the exhaust stream of a diesel engine. The heat from the exhaust gases transforms DEF into ammonia and carbon dioxide.
2. Catalytic Reaction: The ammonia then reacts with NOx in the presence of a catalyst, converting it into nitrogen and water vapor, both of which are harmless to the environment.
3. Emission Reduction: This reaction significantly reduces the amount of NOx emitted from the exhaust, helping vehicles comply with stringent emissions regulations.

Benefits of Using DEF

• Environmental Impact: By reducing NOx emissions, DEF helps decrease air pollution and contributes to cleaner air quality.
• Engine Performance: Proper use of DEF can enhance the performance and efficiency of diesel engines by allowing them to run cleaner and cooler.
