Publication number: 20210310433Abstract: A multi-cylinder opposed piston engine (100) can include one or more sensors, such as oxygen or nox sensors (132, 134, 136, 138, 142), for each cylinder (103) of the multi-cylinder opposed piston engine (100). The sensors (132, 134, 136, 138, 142) are in communication with an engine control unit (102) that can receive measurements and other data from the sensors. In one example, each cylinder (103) includes one or more sensors (132, 134) located adjacent to exhaust ports (144) of each individual cylinder (103). In another example, each cylinder (103) includes one or more sensors (136, 138) located in an exhaust passageway (146) of each individual cylinder (103). In some examples, the multi-cylinder opposed piston engine (100) can include multiple crankshafts (114, 116). For example, the multi-cylinder opposed piston engine (100) can include two crankshafts (114, 116), where each crankshaft (114, 116) engages, either directly or indirectly, one of two opposed pistons (104, 106) of a cylinder (103).Type: ApplicationFiled: September 25, 2017Publication date: October 7, 2021Applicant: Cummins Inc.Inventors: J.

Patent number: 11053881Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.Type: GrantFiled: October 14, 2015Date of Patent: July 6, 2021Assignee: Cummins Inc.Inventors: Phanindra V. Garimella, Paul V. Moonjelly, Edmund P. Hodzen, Ming-feng Hsieh, Gayatri Adi, Gokul Vishwanathan

Patent number: 11035310Abstract: Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.Type: GrantFiled: October 14, 2015Date of Patent: June 15, 2021Assignee: Cummins Inc.Inventors: Phanindra V.

Patent number: 10927741Abstract: A method includes determining whether a urea refill event is detected, and clearing a quality accumulator value and clearing a latching abort command. The method includes determining whether urea fluid quality check abort conditions are met, and clearing the urea quality accumulator, latching the abort command, and exiting the reductant fluid quality check. In response to the abort conditions not being met, incrementing the urea quality accumulator according to an amount of urea being injected, and comparing the accumulated urea quantity to a low test threshold. The method includes, in response to the accumulated urea quantity being greater than the low test threshold, comparing the accumulated urea quantity to a high test threshold, and in response to the urea quantity being greater than the high test threshold, determining whether the a NOx exceedance is observed and clearing a urea quality error in response to the NOx exceedance not being observed.Type: GrantFiled: February 4, 2019Date of Patent: February 23, 2021Assignee: Cummins Emission Solutions Inc.Inventors: Xi Wei, David Samuel Everard, Baohua Qi, Mickey R.
