Sierra's emissions systems division will show its model BG-3 engine particulate partial flow sampling system for the first time in public at the Testing-Expo in Novi, Michigan October 25-27, 2006
The model BG-3 provides accurate, repeatable engine particulate matter (PM) emissions measurements for transient and steady-state engine and vehicle testing.
Led by the model BG-3, particulate partial flow sampling of particulate emissions has gained great acceptance and popularity due to clear advantages over CVS systems.
Designed to reduce the capital and operating costs associated with full-flow dilution testing and accelerate development and certification cycles, the BG-3 is ideal for transient test cycles of diesel, gasoline, or natural gas engines of any size to be used in both engine and chassis test cells.
It is also exceptionally suited for steady-state test cycles as well.
The BG-3's patented transient dilution airflow control (TDAC) is at the heart of its sampling speed.
TDAC is Sierra's ultra fast flow apportionment, measurement and control system to execute proportional sampling effectively.
Using TDAC, the BG-3 accomplishes transient proportional sampling to accurately compensate for large variations of change in engine speed, load, airflow, and fuel valves over short time frames during the transient cycle testing.
The BG-3 was developed to ISO 16183 standards and comes with user friendly software that allows the knowledgeable engineer the diversity of testing any size or fueled engine for particulates calibration and trouble shooting of the system either locally or remotely.
