Particulate Emissions PN vs. PM and GDI

With current, and potential future, regulations on particulate emissions from internal combustion engines becoming more stringent, deeper knowledge into reduction of these emissions is sought after.  Upon completion of this course, learners will:

• Have a foundation in particulate emissions and why they matter.
• Gain a basis for particulate matter (PM) composition, physical properties, measurement techniques and common terminology.
• Be armed with real life, current research results that demonstrate emission results for gasoline direct injection engines.
• Be able to distinguish between particle size and particle number for particulate emissions and identify measurement techniques for each.
• Gain a basis for how various emission metrics relate to one another along with benefits/pitfalls to relationship methodology.

Ultimately, this course will arm learners with critical knowledge of internal combustion particulate emission measurement and mitigation techniques.

Those wanting to gain deeper knowledge on particulate emissions associated with internal combustion engines. Learners seeking a cutting-edge perspective on current research and deeper look at the metrics associated with particulate matter reduction.  The content in this course appeals to emissions engineers, engineering students, ICE enthusiasts, ICE researchers and chemists alike.
