Super Cool Testing

Engine dyno testing with low temperature capable, independent control of the intake manifold air temperature and engine coolant temperature has become increasingly important as engine performance and combustion recipes are tailored to meet low emission standards.

Engine operation during light duty driving and engine warm-up conditions can lead to undesirable effects such as visible white, brown, and yellow smoke. The U.S. EPA and other regulatory agencies have also begun to require some level of emissions compliance in the operating regime where the engine has not yet reached normal operating temperatures. Three of the test cells at AEI have been configured to offer testing services with the following capabilities:

▪ Eddy current dynamometer with up to 800 HP absorption
▪ Motoring dynamometers with 600 to 800 HP
▪ Independent engine coolant control down to 100°F
▪ Independent intake manifold temperature control down to 40°F
▪ Exhaust measurements include: NOx, unburned HC, and smoke
▪ Standard test cell instrumentation for temperatures and pressures
▪ Fuel consumption measurements
▪ Readily available fuel types: ULSD, JP8, #1 diesel, climatized diesel. Test cell is capable of running specialty fuels from drums.

NOTE: The above temperature ranges are available at the test cell with no special setup required. Lower temperatures can be achieved upon request. Please call for further information.
