BG3 Partial Flow Dilution

Overview

In use since 2004, BG3 PFD (Partial Flow Dilution) technology effectively performs engine research and development to accurately sample exhaust PM (Particulate Matter) emissions over both steady state and transient test cycles (Read Case Study). On January 7, 2011, PFD was signed into law and is now included in the United States Federal Register as a legally recognized alternative method to CVS in 40 CFR part 1065 for engine certification. The Direct Final Rule (DFR) contains, among other things, the unprecedented allowance to use PFD for engine emissions PM transient certification testing. Learn more…BENEFITS / FEATURES

• Approximately 1/10th of CVS system cost of ownership
• Approximately 1/100th to 1/1000th the annual energy usage versus a CVS, depending on CVS size and design
• Can sample PM on engines of any size and on any fuel in both engine and chassis test cells
• Patented partial flow dilution tunnel has ultra-low particulate loss and requires no cleaning when operated properly
• Integrity of internal flow systems and proprietary daily mirror calibration method yield excellent accuracy and repeatability of PM results over a wide range of dilution ratios
• Easily portable from cell to cell to maximize flexibility and return on investment
• Satisfies all ISO 8178 or 8-Mode, ISO 16183, 40 CFR 1065 and CFR Part 89 and Directive 1999/96/EC among many others
• Ability to accurately measure PM either pre and post catalyst and/or DPF for research or DF testing
