RISExperimental Study of the Impact of Ethanol Content on Partially Premixed Combustion With Ethanol-Gasoline Blends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As ethanol production increases and the demand for gasoline in spark ignition engines decreases over the next few decades, the use of these fuels in compression ignition systems is expected to increase. This raises the ...
Integration of a Dual Mode SI HCCI Engine Into Various Vehicle Architectures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simulation study was performed to evaluate the potential fuel economy benefits of integrating a dualmode SIHCCI engine into various vehicle architectures. The vehicle configurations that were considered include a ...
A Quasi-Dimensional Fuel Distribution Model for a Radially Stratified Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several combustion strategies leverage radial fuel stratification to adapt cylinder composition between the center of the chamber and the outer regions independently. Spark-assisted compression ignition (SACI) relies on ...
Experimental Study of the Effect of Start of Injection and Blend Ratio on Single Fuel Reformate RCCI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
On the Effects of Injection Strategy, Exhaust Gas Recirculation, and Intake Boost on TSCI With Wet Ethanol
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using a split injection of wet ethanol, where a portion of the fuel is injected during the compression stroke, has been shown to be an effective way to enable thermally stratified compression ignition (TSCI), an advanced ...
An Experimental Comparison of Methanol Combustion Strategies: Spark Ignition Versus Compression Ignition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Methanol has garnered significant attention over the past few years due to its potential as a hydrogen carrier in a future green economy. As a result, it is a leading candidate to displace fossil fuels in the transportation ...
Computational Fluid Dynamics Simulations of the Effect of Water Injection Characteristics on TSCI: A New, Load-Flexible, Advanced Combustion Concept
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Homogeneous charge compression ignition (HCCI) combustion has the potential for high efficiency with very low levels of NOx and soot emissions. However, HCCI has thus far only been achievable in a laboratory setting due ...
Exploring the Effects of Piston Bowl Geometry and Injector Included Angle on Dual-Fuel and Single-Fuel RCCI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Development of a Device for the Nondestructive Thermal Diffusivity Determination of Combustion Chamber Deposits and Thin Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental radiation chamber has been developed to nondestructively measure the thermal diffusivity of a combustion chamber deposit (CCD) layer. The accumulation of CCD shifts the operability range of homogeneous ...
