Debunking Myths About Tier 4 Final Diesel Engines

In its most recent regulations on emission reduction, Tier 4 Final, the Environmental Protection Agency (EPA) requires significant reductions in nitrogen oxide (NOx) and particulate matter over previous requirements. Because of these changes, many microgrid operators and others in the market that rely on diesel generators for standby power have questions about the overall benefits and the emissions of Tier 4 Final compliant diesel engines.

A new white paper from Volvo Penta debunks some of the most common myths about Tier 4 Final diesel engines by presenting data on Volvo Penta’s solution. The paper explains how Volvo Penta’s Selective Catalytic Reduction (SCR) process reduces NOx emissions. The authors also present highlights of a recent Microgrid Knowledge webinar featuring Volvo Penta, PowerSecure and Miratech, where experts from the companies discussed the new emissions standards and environmentally friendly diesel engines.

The paper features a question and answer session with Volvo Penta’s Darren Tasker, who shares insights around how Tier 4 Final diesel engines are tested in the field. He also explores how Tier 4 Final engines compare to previous tiers in terms of fuel efficiency, maintenance costs, lifespan, and price.
