The Effects of Thick Thermal Barrier Coatings on Low-Temperature Combustion

Yan, Ziming; Gainey, Brian; Gohn, James; Hariharan, Deivanayagam; Saputo, John; Schmidt, Carl; Caliari, Felipe; Sampath, Sanjay; Lawler, Benjamin (2020)

An experimental study was conducted on a Ricardo Hydra single-cylinder light-duty diesel research engine. Start of Injection (SOI) timing sweeps from -350 deg aTDC to -210 deg aTDC were performed on a total number of five ...
Investigation Into Reactivity Separation Between Direct Injected and Premixed Fuels in RCCI Combustion Mode

Yan, Ziming; Gainey, Brian; Hariharan, Deivanayagam; Lawler, Benjamin (2019)

This experimental study focuses on the effects of the reactivity separation between the port injected fuel and the direct injection fuel, the amount of external-cooled exhaust gas recirculation (EGR), and the direct injection ...
Exploring the effects of piston bowl geometry and injector included angle on dual-fuel and single-fuel RCCI

Hariharan, Deivanayagam; Mozhgan, Rahimi Boldaji; Yan, Ziming; Gainey, Brian; Lawler, Benjamin (2021)

Reactivity control compression ignition (RCCI) is a low-temperature combustion technique that has been proposed to meet the current demand for high thermal efficiency and low engine-out emissions. However, its requirement ...
Experimental study of the effect of start of injection and blend ratio on single fuel reformate RCCI

Hariharan, Deivanayagam; Mamalis, Sotirios; Yan, Ziming; Gainey, Brian; Lawler, Benjamin (2020)

A new concept of single fuel reactivity-controlled compression ignition (RCCI) has been proposed through the catalytic partial oxidation (CPOX) reformation of diesel fuel. The reformed fuel mixture is then used as the low ...
Experimental Study of Spark-Ignition Combustion using the Anode Off-Gas from a Solid Oxide Fuel Cell

Ran, Zhongnan; Assanis, Dimitris; Hariharan, Deivanayagam; Mamalis, Sotirios (2020)

Hybridizing Solid Oxide Fuel Cells (SOFCs) with internal combustion engines is an attractive solution for power generation at high electrical conversion efficiency while emitting significantly reduced emissions than ...
Experimental Study of Lean Spark Ignition Combustion using Gasoline, Ethanol, Natural Gas, and Syngas

Ran, Zhongnan; Hariharan, Deivanayagam; Lawler, Benjamin; Mamalis, Sotirios (2019)

In the development of internal combustion engines, engineers and researchers are facing the challenge of improving engine efficiency while reducing harmful exhaust emissions. Previous research has shown that lean combustion ...
Efficiency and Emissions Characteristics of an HCCI Engine Fueled by Primary Reference Fuels

Yang, Ruinan; Hariharan, Deivanayagam; Zilg, Steven; Lawler, Benjamin; Mamalis, Sotirios (2018)

This article investigates the effects of various primary reference fuel (PRF) blends, compression ratios, and intake temperatures on the thermodynamics and performance of homogeneous charge compression ignition (HCCI) ...
Multiple injection strategies for reducing HC and CO emissions in diesel-methane dual-fuel low temperature combustion

Hariharan, Deivanayagam; Krishnan, Sundar Rajan; Srinivasan, Kalyan Kumar; Sohail, Aamir (2021)

Dual fuel low temperature combustion (LTC), while promising extremely low engine-out emissions of oxides of nitrogen (NOx) and particulate matter (PM), is beset with high unburned hydrocarbon (HC) and carbon monoxide (CO) ...
A comprehensive experimental investigation of low-temperature combustion with thick thermal barrier coatings

Yan, Ziming; Gainey, Brian; Gohn, James; Hariharan, Deivanayagam; Saputo, John; Schmidt, Carl; Caliari, Felipe; Sampath, Sanjay; Lawler, Benjamin (2021)

Thick thermal barrier coatings (TBCs) have a significant potential to increase thermal efficiency by reducing heat transfer losses. However, in conventional combustion modes, the drawbacks associated with charge heating ...
Effects of Single versus Two-Stage Heat Release on the Load Limits of HCCI using Primary Reference Fuels

Hariharan, Deivanayagam; Yang, Ruinan; Mamalis, Sotirios; Lawler, Benjamin (2019)

Homogeneous Charge Compression Ignition (HCCI) enables combustion with high efficiency and low emissions. Control over the combustion process and its narrow operating range are still the biggest challenges associated with ...
Catalytic Partial Oxidation Reformation of Diesel, Gasoline, and Natural Gas for Use in Low Temperature Combustion Engines

Hariharan, Deivanayagam; Yang, Ruinan; Zhou, Yingcong; Gainey, Brian; Mamalis, Sotirios; Smith, Robyn E; Lugo-Pimentel, Michael A; Castaldi, Marco J; Gill, Rajinder; Davis, Andrew; Modroukas, Dean; Lawler, Benjamin (2019)

Onboard reforming has relevance to both conventional and advanced combustion concepts. Most recently, onboard reforming has been proposed to enable “Single-Fuel RCCI” combustion and therefore, this paper explores catalytic ...
Single-fuel reactivity controlled compression ignition through catalytic partial oxidation reformation of diesel fuel

Hariharan, Deivanayagam; Rahimi Boldaji, Mozhgan; Yan, Ziming; Mamalis, Sotirios; Lawler, Benjamin (2019)

A single-fuel RCCI concept has been proposed to avoid the need for a secondary fuel system required for conventional RCCI by generating the secondary fuel from the primary fuel through catalytic partial oxidation (CPOX) ...
