Abstract:
A back-up battery system is provided for use with a real-time clock of an on-board device controller. In its normal operation, the real-time clock (RTC) is powered by a primary power source, such as a vehicle battery. When the primary source is interrupted, the back-up battery system is invoked to provide back-up power to the RTC. The system includes a low voltage dry cell battery mounted within a fuse component configured for electrical engagement within the vehicle fuse block. In one embodiment, a relay is interposed between the fuse component and the RTC to make and break the back-up power circuit in response to the state of the primary power source. In another embodiment, the battery within the fuse component is replaceable, with the fuse component including a base and a removable cap. In still another embodiment, the battery within the fuse component is a rechargeable battery, and the back-up power system includes a recharging circuit operable with the primary power source.
Connectivity System For Internal Combustion Engine With Aftertreatment System
A connectivity system includes an engine control module, a pump assembly remote from the engine control module, and a connectivity unit mounted to the pump assembly. The connectivity unit is communicatively coupled to the engine control module and configured to transmit data received from the engine control module to a device external to a vehicle with which the connectivity system is associated.

A selective catalytic reduction system may include a single housing defining a single centerline axis. The selective catalytic reduction system may also include a diesel particulate filter disposed within the single housing and having a DPF center axis aligned with the single centerline axis. The selective catalytic reduction system may also include an SCR catalyst disposed within the single housing and having a center axis aligned with the single centerline axis. In some implementations, the diesel particulate filter may include one or more SiC filters. In some implementations, the SCR catalyst may include one or more extruded SCR catalysts.
