Abstract: Described herein is an air intake device for an engine of a vehicle equipped with a transport refrigeration unit (TRU). The device comprises a housing defining a shape of the device. The device is adapted to be fixedly or removably configured at a predetermined position in the vehicle, the TRU, a container or chassis associated with the vehicle, or a trailer associated with the vehicle such that the device facilitates inflow of ambient air therewithin and directs the ambient air towards the engine.

Abstract: A system for controlling engine crankshaft deceleration in an internal combustion engine is operable to determine whether the engine is operating with low inertia, to monitor an operational status of an engine retarding device configured to produce an engine retarding torque for decreasing rotational speed of the engine crankshaft, and to limit the retarding torque produced by the engine retarding device if the engine retarding device is operational and if the engine is operating with low inertia.
