Abstract: An exhaust system for an engine includes an exhaust conduit, a selective catalytic reduction (SCR) device in the exhaust conduit, and a diesel emission fluid (DEF) system. The diesel emission fluid system includes a DEF delivery controller structured to receive a condition signal indicative of a DEF deposition risk condition in the exhaust system, and to command an increased heat energy output of a preheater to preheat DEF to be admitted into the exhaust conduit, such that a temperature of the DEF is increased to a deposition-mitigation temperature. Related methodology and control logic is also disclosed.

Abstract: A system for determining a spray pattern of an injector is disclosed. The system includes a chamber having a means for mounting the injector and a grid disposed within the chamber, the grid includes an array of orifices to receive fluid sprayed by the injector. The system also includes multiple containers positioned beneath the chamber for collecting the fluid and multiple tubes to connect the grid to the multiple containers, where each tube allows flow of fluid from an orifice to a container. The system also includes a multiple load cells to generate a voltage signal corresponding to an amount of fluid collected in each container and multiple solenoids to drain the fluid from each container. Further, the system includes a control module to generate an output indicative of the amount of fluid collected in each container and a distribution pattern of the collected fluid.

Abstract: A cost optimization system for optimizing costs of consumables for a machine is provided. The cost optimization system includes an input module configured to receive cost information relating to a unit cost of each of a plurality of consumables. A control module is communicably coupled to the input module. The control module is configured to receive the cost information from the input module. Further, the control module is configured to monitor one or more parameters of the machine. The control module is configured to control operation of the machine based on the one or more parameters to control use of the plurality of consumables to optimize the machine operating costs.

Abstract: A method is disclosed for detecting a malfunctioning of a tank containing fluid, using a processor and a level sensor. The processor calculates a rate of consumption of the fluid in the tank. The processor further calculates an estimated change in level of the fluid in the tank based on the rate of consumption of the fluid. The level sensor determines a measured change in level of the fluid in the tank. The processor compares the estimated change in level of the fluid with the measured change in level of the fluid. The processor further determines the malfunctioning of the tank if a difference between the estimated change in level of the fluid and the measured change in level of the fluid exceeds a predetermined value. The fluid contained in the tank is a diesel exhaust fluid.
