Journal ArticleDOI
Fuel efficient exhaust thermal management for compression ignition engines during idle via cylinder deactivation and flexible valve actuation
Chuan Ding,Leighton Roberts,David Fain,Aswin K Ramesh,Gregory M. Shaver,James McCarthy,Michael Ruth,Edward Koeberlein,Eric Holloway,Douglas Nielsen +9 more
TL;DR: In this article, the authors demonstrate that cylinder deactivation improves exhaust thermal management during both loaded and lightly loaded idle conditions, and demonstrate that coupling cylinder deactivations with flexible valve motions results in additional benefits during lightly-loaded idle operation.
Journal ArticleDOI
Effect of intake valve closure modulation on effective compression ratio and gas exchange in turbocharged multi-cylinder engines utilizing EGR
R Modiyani,Lyle Kocher,D. G. Van Alstine,Edward Koeberlein,Karla Stricker,Peter H. Meckl,Gregory M. Shaver +6 more
TL;DR: In this paper, the authors used data from, and an experimentally validated simulation model for, a multi-cylinder engine with variable geometry turbocharging, cooled exhaust gas recirculation, and fully flexible variable valve actuation.
Journal ArticleDOI
Utilizing low airflow strategies, including cylinder deactivation, to improve fuel efficiency and aftertreatment thermal management:
Aswin K Ramesh,Gregory M. Shaver,Cody M Allen,Soumya Nayyar,Dheeraj B Gosala,Dina M Caicedo Parra,Edward Koeberlein,James McCarthy,Doug Nielsen +8 more
TL;DR: In this paper, the authors estimate that 30% of the fuel consumed during typical heavy-duty vehicle operation occurs at elevated speeds with low-to moderate loads below 6.5 bar brake mean effective pressure.
Journal ArticleDOI
Reducing Diesel Engine Drive Cycle Fuel Consumption through Use of Cylinder Deactivation to Maintain Aftertreatment Component Temperature during Idle and Low Load Operating Conditions
Mrunal C Joshi,Dheeraj B Gosala,Cody M Allen,Kalen R Vos,Matthew Van Voorhis,Alexander H Taylor,Gregory M. Shaver,James McCarthy,Dale Arden Stretch,Edward Koeberlein,Lisa Farrell +10 more
TL;DR: In this paper, cylinder deactivation (CDA) was used to maintain desired aftertreatment temperatures during idle conditions, which resulted in fuel savings of 3.0% over the HD-FTP drive cycle.
Journal ArticleDOI
Fuel-efficient exhaust thermal management using cylinder throttling via intake valve closing timing modulation:
Akash Garg,Mark Magee,Chuan Ding,Leighton Roberts,Greg Shaver,Edward Koeberlein,Ray Shute,David Koeberlein,James McCarthy,Douglas Nielsen +9 more
TL;DR: In this paper, the effect of cylinder throttling on exhaust gas temperatures, fuel consumption, in-cylinder combustion and emissions was analyzed, and a significant increase in turbine outlet temperature accompanied by a decrease in fuel consumption and NOx and particulate matter emissions was observed.
