Abstract:

Disclosed embodiments involve a rechargeable lithium-ion battery module assembly for use as an auxiliary power unit (APU), particularly in commercial trucks. Battery module assembly is recharged through the semi-trailer truck's alternator during engine operation. Battery module assembly has active voltage control capabilities to reduce charge time. Each battery array has two collector plate printed circuit board assemblies (PCBA) and two banks of lithium iron phosphate (LFP) battery cells. Individual battery cells are wire bonded to the collector plate PCBs, one of such PCBs incorporates a battery management system to monitor the electrical parameters and state of charge of the battery cells in the system. Battery cells are thermally coupled to an aluminum enclosure with a thermal gap filling material. Using different chemistries for the APU and the starting battery of the commercial truck, and methods of sequential charge and discharge cycles of each, without any other discrete device.

Abstract:

Methods and systems for estimating an amount of residual or retained fuel that remains in a cylinder from a first cycle of the cylinder to a second cycle of the cylinder are described. In one example, the amount of residual fuel is estimated in response to a temperature of an oxidation catalyst. The retained fuel amount may then be the basis for adjusting fuel injection amounts during the second cycle of the cylinder.

Abstract:

Methods and systems for supplying post injection fuel to a two stroke diesel engine are described. In one example, post injection fuel timing is adjusted responsive to an amount of internal residual combustion products in a cylinder so that less post injected fuel may be trapped in the cylinder for a subsequent cycle of the cylinder. The start of post injection fuel timing and the amount of post injection fuel may be adjusted responsive to internal residual in the cylinder.
