Abstract: A system to dose and mix hydrocarbon is disclosed, which includes a twin-parallel turbocharger equipped engine, a mixer coupled to exhaust outlets of the turbines of the twin-parallel turbocharger equipped engine, and a hydrocarbon dosing unit coupled to the mixer. A method of manufacturing the compact hydrocarbon dosing and mixing system is also disclosed, as is a method of dosing and mixing hydrocarbon.

Abstract: An exhaust mixer provided may be used for mixing an additive, such as urea, in exhaust fluid flow. The exhaust mixer may be useful in reducing or preventing build-up of solid additive deposits by increasing efficiency of mixing of the additive. The exhaust mixer may be located at least partially within a mixing conduit and includes plurality of elongate mixing blades held in spaced configuration by a support. Each mixing blade may have a longitudinal axis extending along a longitudinal axis of the mixing conduit, wherein an injector module may be located upstream of the inlet of the mixing conduit.

Abstract: A method for monitoring thermal patterns of a machine includes identifying at least one location for positioning a robotic arm. The robotic arm is equipped with at least one of a visual camera and a thermal imaging camera adapted to capture a visual image and a thermal image of a portion of the machine, respectively. The method includes defining a plurality of segments of the portion by allocating a plurality of grids to the portion. Further, the portion of the machine is scanned by the robotic arm, based on the plurality of grids with the at least one of the visual camera and the thermal imaging camera. A component of the machine is detected, when the thermal patterns recorded for the component deviate from a predefined thermal pattern. The portion of the machine is then rescanned for determining changes in the thermal patterns as a function of time.
