SAKOR Technologies Inc., a recognized leader in the area of high-performance
dynamometer systems, announces that it recently provided a performance test
stand for validating designs for new hydraulic variable timing cam phaser
systems for a major international provider of powertrain components.
Powerful and flexible, the cam phaser test stand will be used for research
and development on engine timing designs that improve engine fuel
efficiency. Simulating an engine using an electric dynamometer is cleaner
and safer than using an actual internal combustion engine and reduces the
costs and time needed for cam phaser design testing.

The custom built system is designed for use with cam phasers driven by oil
pressure. The test system simulates different engine designs, simulating cam
torque pulses using two high speed low inertia AccuDyne™ AC Dynamometers and
the industry-leading DynoLAB™ data acquisition and control system. One
dynamometer drives the timing chain as if it were the engine, while the
other simulates cam shaft torque pulses. Parts for testing are mounted in a
thermal chamber that can be run at temperatures ranging from -40 to 150°C.
This enables engineers to simulate temperatures encountered by those
starting engines in all climates. The system controls oil pressure to
advance or retard timing of the cam shaft relative to the engine.

The SAKOR system features a 60 kilowatt dynamometers that can operate at up
to 8500 revolutions per minute (rpm) to simulate the engine. A 235 kW
ultra-low inertia dynamometer is used to simulate the high frequency torque
pulses found on a cam shaft. The test stand can be easily adjusted, so it
can accommodate a wide range of cam phaser designs. The DynoLAB™ data
acquisition and control system provides reliable fully automated test
procedures for all customer testing protocols.

“SAKOR is dedicated to helping customers design the next generation of fuel
efficient engines in ways that do not require huge expensive facilities to
conduct testing of components,” said Randal Beattie, president of SAKOR. “To
the best of our knowledge, ours is the first system capable of simulating
dynamic cam shaft torque pulsing in real time and in a clean lab
