End-gas autoignition fraction and flame propagation rate in laser-ignited primary reference fuel mixtures at elevated temperature and pressure

Autor: Gregory James Hampson, Kara Gustafson, Jessica Tryner, Bret Windom, Daniel B. Olsen, Andrew Zdanowicz, Jeffrey Mohr, Anthony J. Marchese

Publikováno v: Combustion and Flame. 234:111661

Knock in spark-ignited (SI) engines is initiated by autoignition of the unburned gasses upstream of spark-ignited, propagating, turbulent premixed flames. Knock propensity of fuel/air mixtures is typically quantified using research octane number (RON

High Efficiency Natural Gas Engine Combustion Using Controlled Auto-Ignition

Autor: Gregory James Hampson

Publikováno v: ASME 2019 Internal Combustion Engine Division Fall Technical Conference.

Increasingly restrictive limits on Oxides of Nitrogen - NOx levels and desire for low methane emissions from gas engines are driving the change from lean-burn to stoichiometric combustion strategies on heavy-duty on-highway natural gas engines in ord

EGR and Backpressure Effects on Knock Behavior in Stoichiometric Natural Gas Engines

Autor: Domenico Chiera, D. Ryan Williams, Knutzen Henry David Gemmill, Gregory James Hampson

Publikováno v: Volume 1: Large Bore Engines; Fuels; Advanced Combustion.

Increasingly restrictive limits on NOx levels are driving the change from lean-burn to stoichiometric combustion strategies on heavy-duty on-highway natural gas engines in order to take advantage of inexpensive and effective three-way catalyst techno

Mechanism for High Velocity Turbulent Jet Combustion From Passive Prechamber Spark Plug

Autor: Michael B. Riley, Gregory James Hampson, Domenico Chiera

Publikováno v: ASME 2012 Internal Combustion Engine Division Fall Technical Conference.

Next generation passive prechamber spark plugs for high BMEP natural gas engines require long ignition delay for durability, fast combustion for efficiency, and low COV for lean engine operation. Additionally, a successful plug should have long life,

Lean Limit Extension for High BMEP Gas Engines via Novel Electronic Ignition and Prechamber Plug: Higher Efficiency and Lower NOx in Open Chamber Engines

Autor: Gregory James Hampson, David Ahrens, David C. Petruska, Domenico Chiera, Michael B. Riley, Nolan Polley

Publikováno v: ASME 2011 Internal Combustion Engine Division Fall Technical Conference.

Large bore natural gas engines have the perennial challenge to achieve ever higher efficiency with ever lower NOx emissions, while maintaining stable combustion, avoiding misfire and engine knock. A primary strategτy to achieve these goals is to run
