Abstract: A transport power system for generating power is provided. The transport power system includes an extended mid-pipe having a flexible member and an insulated member that is connected to the flexible member. The flexible member is coupled to an exhaust manifold disposed on a diesel prime mover that is configured to generate exhaust. The extended mid-pipe is configured to receive the exhaust from the exhaust manifold. The diesel oxidation catalyst (DOC) is coupled to the insulated member. The transport power system also includes a housing containing the DOC and the diesel prime mover. The DOC is positioned away from the diesel prime mover such that the DOC is configured to be unstacked in a depth direction of the housing. The insulated member is configured to maintain a temperature of the exhaust to at or above an activation temperature of the DOC.

Abstract: Exhaust assemblies for emitting an exhaust from a prime mover while in transit are disclosed. The exhaust assembly can include a tail pipe that includes a raiser portion, a soot portion and an undercut outlet. The raiser portion is inclined at a first angle relative to a vertical axis of the exhaust assembly. The raiser portion is configured to receive the exhaust. The soot portion is connected to the raiser portion and is configured to receive the exhaust from the raiser portion. The soot portion is inclined at a second angle relative to the vertical axis. The undercut outlet is disposed at a tail end of the soot portion. The undercut outlet has an upper lip shielding fluid or debris from entering the exhaust assembly via the undercut outlet.

Abstract: A method for monitoring fuel quality of a power system used in transport is provided. The method includes a controller of the power system determining that the prime mover is actively running. The method also includes the controller monitoring an output of a water-in-fuel (WIF) sensor configured to measure an amount of water accumulated in a water collection reservoir of a fuel/water separator that separates water from fuel passing there through. Also, the method includes the controller determining an amount of fuel passing through the fuel/water separator. Further, the method includes the controller calculating a fuel quality score of the fuel based on the output of the WIF sensor and the amount of fuel having passed through the fuel/water separator. The method further includes the controller triggering different alerts based on the calculated fuel quality score.

Abstract: A generator set for a transport climate control unit is provided that is operable at a first frequency and a second frequency. The generator set includes a generator, a prime mover configured to operate at a first non-zero speed and a second non-zero speed that is less than the first non-zero speed, and a genset controller configured to control operation of the generator set. When operating at the first non-zero speed, the genset controller is configured to monitor a prime mover load parameter to determine whether the prime mover is approaching or has exceeded an overload or stall situation. The genset controller is configured to reduce the speed of the prime mover from the first non-zero speed to the second non-zero speed to prevent the overload or stall situation.
