SSCD90-1000-3300 90kW Diesel Engine Electric Dynamometer Test Bench
System
1. SSCD90-1000-3300 90kW Diesel Engine Electric Dynamometer Test Bench System Description
The diesel engine electric dynamometer test bench system uses an AC
electric dynamometer as its test core and is equipped with an
imported four-quadrant active variable frequency inverter system as
its controller. It can operate in four quadrants and directly feed
energy back into the grid. The XLE-1000 measurement and control
system serves as the control core, automatically completing test
cycles defined by regulations and purchasers. It can integrate
external auxiliary equipment such as transient fuel consumption
meters and thermostats, and is equipped with a data acquisition
system to collect engine parameters, which are then recorded,
processed, displayed, and generated into test reports in real time.
