A new compact system designed for the dynamic testing of small motors through their whole speed
and torque range is now available from Brookes B
Green Ltd. The system consists of a dynamometer incorporating
a hysteresis load brake.

SAKOR Technologies, Inc., a recognized leader in the implementation of instrumentation products for powertrain system testing , announces Version 4.1 of its DynoLAB™ Test Executive and the DynoLAB™ PT system with a complete, regenerative AC small engine dynamometer . ...combination is ideal for small engine components found in lawn care tools, outboard motors , motorcycles, and generators.
Drive Cycle Analysis, Measurement of Emissions and Fuel Consumption of a PHEV School Bus: Preprint
However, the savings
seem to result from the smaller engine rather than hybridization since fuel consumption tests on the UDDSHDV and the OCC with the
hybrid system switched off showed no significant difference from the CS mode results (when both were run... The limited electric motor assist to the 149-kW engine resulted in occasional trace miss in CS mode and in roughly 5% less cycle
energy as measured at the dynamometer rolls in CS relative to CD mode.
...pieces of the intake manifold to block air flow from the throttle to the three motored cylinders. Small air filters were added to the runners ofthese cylinders to allow air to enter them to reduce
the resistance upon the dynamometer caused by pumping air through them. The exhaust
manifold was modified to keep the test cylinder's exhaust isolated through the entire exhaust system .
