A system for dynamically mitigating resonance in a transport refrigeration unit (TRU) during a mission, having: a TRU controller configured for operating a TRU engine during the mission according to an operational baseline, and while operating the TRU engine, contemporaneously performing steps including: obtaining a first set of data that comprises real time measurements from one or more accelerometers installed in the TRU; converting the real measurements to a second set of data that comprises real time shock and vibration data; processing the second set of data in a control loop to determine an updated operational baseline that avoids resonance detected in the first set of data; and operating the TRU engine according to the updated operational baseline.

Mitigation of resonance in a transport refrigeration unit

A transport refrigeration unit system () for cooling a trailer compartment () is provided. The transport refrigeration unit system () includes an engine for controlling a cooling rate capacity, the engine operable at a nominal high speed and a nominal low speed. Also included is a controller () in operative communication with the engine to control an engine speed of the engine. Further included is a user interface () in operative communication with the controller (), the user interface () providing a high capacity cooling mode to a user, wherein initiation of the high capacity cooling mode includes the engine operating at a speed greater than the nominal high speed to result in a high capacity cooling rate.

Transport refrigeration system and method of operation

A system for testing a particulate filter system includes a filter controller connected to the particulate filter system and a vehicular computer configured to determine at least one engine condition. The filter controller is configured to control a condition of a component of the particulate filter system and the vehicular computer is operatively connected to the filter controller to communicate therewith. The vehicular computer compares the condition of the component of the particulate filter system with the engine condition to determine whether the component of the particulate filter system is functioning properly.

Particulate filter test system and method

A transport refrigeration system having a structural framework supporting a refrigeration unit including a condenser heat exchanger supported in an upper region of the framework and an engine and an electric generator powered by the engine supported by the framework in an engine compartment in a lower region of the framework, includes a pair of vertically disposed condenser fan/motor assemblies disposed aft of the condenser heat exchanger in side-by-side relationship and above the engine compartment; and a flow partition extending vertically between the pair of condenser fan/motor assemblies.

Dual condenser fans with center partition

An engine driven generator () is provided with first and second stage fans () at one end thereof. The two-stage fan system draws in ambient air and forces it through the generator windings () and rotor-stator air gap () for the purpose of improving generator cooling. Stationary guide vanes () are disposed between the two fans () for the purpose of de-swirling the flow therebetween. The fans are of the centrifugal type and are preferably backward curved.
