Clean Diesel: Fuel System and Emission Limits

Clean Diesel: Fuel System and Emission Limits

Learning Objective

Understand the fuel system and after-treatment components of diesel engines and the European and American emission legislation.

What do you already know about diesel engine emission limits and after-treatment systems?

Introduction to Diesel Fuel System

Overview of the fuel injection process and key components such as fuel pump, injectors, and fuel filters.

After-Treatment Systems

Explanation of selective catalytic reduction (SCR), diesel particulate filters (DPF), and exhaust gas recirculation (EGR) systems.

European Emission Standards

Overview of Euro 6 standards and their impact on diesel engine design and after-treatment systems.

American Emission Regulations

Explanation of EPA regulations, including Tier 4 standards, and their implications for diesel engine manufacturers.

Emission Control Components

Detailed description of components like diesel oxidation catalysts (DOC) and selective catalytic reduction (SCR) systems.

Emission Reduction Processes

Explanation of how the after-treatment systems reduce nitrogen oxides (NOx) and particulate matter (PM) emissions.

Comparing European and American Legislation

Highlighting the differences and similarities between European and American legislation on diesel engine emissions.

Case Studies

Examining real-world examples of diesel engine manufacturers adapting to meet emission limits in both regions.

Conclusion and Reflection

Summarize key learnings and encourage students to reflect on the importance of emission control in diesel engines.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
