Methods For Controlling Combustion Of Blended Biofuels

View page
US Patent:
20130024094, Jan 24, 2013
Filed:
Dec 31, 2010
Appl. No.:
13/519756
Inventors:
Gregory Matthew Shaver - Lafayette IN, US
David Benjamin Snyder - Franklin IN, US
Carrie Michele Hall - Lafayette IN, US
Gayatri Adi - West Lafayette IN, US
Michael Bunce - Knoxville TN, US
International Classification:
F02B 47/08
F02M 25/07
F02D 41/30
US Classification:
701104, 701103
Abstract:
A closed-loop control algorithm that reduces the increases in nitrogen oxides (NO) commonly observed with biodiesel combustion while retaining particulate matter (PM) reductions with variable biodiesel blend fractions. One embodiment includes a control algorithm that is closed-loop with regards to combustible oxygen mass fraction (COMF) instead of exhaust gas recirculation (EGR) fraction. Yet another algorithm includes biodiesel blend estimation and “fuel-flexible” accommodation. A physics-based model has also been developed which predicts experimentally observed engine performance and emissions for biodiesel.

Engine Controls Including Direct Targeting Of In-Cylinder [O2]

US Patent:
20200025121, Jan 23, 2020
Filed:
Sep 30, 2019
Appl. No.:
16/587143
Inventors:
- Columbus IN, US
Gayatri Adi - Columbus IN, US
Paul V. Moonjelly - Columbus IN, US
International Classification:
F02D 41/02
F02D 41/14
Abstract:
Unique engine controls and apparatuses, methods and systems relating to the same are disclosed. One embodiment is method which utilizes an in-cylinder [O2] mass fraction model to generate exhaust gas recirculation (EGR) fraction references for both transient and steady state operating conditions. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.

Reference Value Engine Control Systems And Methods

US Patent:
20180274467, Sep 27, 2018
Filed:
Oct 14, 2015
Appl. No.:
15/762461
Inventors:
- Columbus IN, US
Paul V. Moonjelly - Columbus IN, US
Edmund P. Hodzen - Columbus IN, US
Ming-feng Hsieh - Nashville IN, US
Gayatri Adi - Columbus IN, US
Gokul Vishwanathan - Olney MD, US
Assignee:
CUMMINS INC. - Columbus IN
International Classification:
F02D 41/14
F02M 26/05
F02D 41/38
F02D 35/02
F02D 41/00
F02D 41/24
F02D 41/40
Abstract:
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.

US Patent:
20180274475, Sep 27, 2018
Filed:
Oct 14, 2015
Appl. No.:
15/762472

International Classification:
F02D 43/04
F02D 41/30
F02D 41/00
F01N 3/20
B01D 53/94
Abstract:
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.
