The National Wind Technology Center (NWTC) at the Energy Department’s National Renewable Energy Laboratory (NREL) has begun validation work on the first water power technology ever tested in an NREL dynamometer facility. “Though designed to benefit the wind industry, the NWTC’s large dynamometer facility is being leveraged to help advance new ...
"Though designed to benefit the wind industry, the NWTC's large dynamometer facility is being leveraged to help advance new ocean energy technology," said NWTC Director Daniel Laird. ...
VW was able to fool the EPA because the agency only tested the cars on treadmill-like devices called dynamometers and didn't use portable test equipment on real roads. The software in the cars' engine-control computers checked the speed, steering wheel position, air pressure and other factors to determine when dynamometer tests were under way. ...
NREL currently operates 2.5-megawatt and 5-megawatt dynamometers, and a controllable grid interface - grid simulator that can help engineers better understand how wind turbines will react to grid disturbances. Supported by a $45.6 million DOE investment that is cost matched with over $70 million in funds, Clemson University currently operates a drivetrain testing facility with ...
The latest design helps dissipate extremely high thermal energy loads experienced in applications like drawworks, marine winches, cranes, metal processing and dynamometers. The brake’s improved internal design allows for faster drilling and gives original equipment manufacturers (OEMs), distributors and end users the ability to downsize their brake, saving up to $60,000 a ...
“During the on-road portion of our study, the hybrid vans demonstrated a 13 to 20 percent higher fuel economy than the conventional vans,” said NREL Project Engineer Michael Lammert. “During dynamometer testing, three standard drive cycles were chosen to represent the range of delivery routes. ...
In addition to field testing, the NREL team performed dynamometer testing at its Renewable Fuels and Lubricants (ReFUEL) Research Laboratory. During dynamometer testing, the hybrids demonstrated up to a 30 percent improvement in fuel economy, depending on drive cycle, and up to a 32.1percent improvement in ton-miles-per-gallon. ...
The testing will be performed in accordance with the Intermediate Age requirements of the EPA Clean Alternative Fuel Vehicle and Engine Conversion Final Rule as amended in April 2011 which requires engines to be tested outside of the vehicle on an engine dynamometer. Valley Truck, our regional Authorized Dealer and Certified Installer located in the Grand Rapids, Michigan area ...
