RISOptimization Method and Simulation Study of a Diesel Engine Using Full Variable Valve Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variable valve timing technologies for internal combustion engines are used to improve power, torque, and increase fuel efficiency. Details of a new solution are presented in this paper for optimizing valve motions of a ...
Practical Applications of Net Energy Analysis of Upstream Oil and Gas Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Net energy analysis (NEA) has traditionally been utilized by nonindustry actors, such as academics, economists, and regulators. It has not been widely accepted as a beneficial method within the oil and gas industry with ...
Extending Substitution Limits of a Diesel–Natural Gas Dual Fuel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: New drilling techniques have increased availability and decreased costs of oil and gas. The decreased costs have caused an increase in drilling activity. The well sites have a large power demand that is typically met by ...
Performance Degradation and Poison Build-Up of an Oxidation Catalyst in Two-Stroke Natural Gas Engine Exhaust
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to current and future exhaust emissions regulations, oxidation catalysts are increasingly being added to the exhaust streams of large-bore, two-stroke, natural gas engines. Such catalysts have a limited operational ...
Experimental Evaluation of Volatile Organic Compound Quantification Methods for Reciprocating Natural Gas Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compressor stations utilizing large-bore natural gas engines transport natural gas through pipelines worldwide. One emission class regulated by the Environmental Protection Agency (EPA) is volatile organic compounds (VOCs), ...
Prediction of Probabilistic Shock Initiation Thresholds of Energetic Materials Through Evolution of Thermal-Mechanical Dissipation and Reactive Heating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ignition threshold of an energetic material (EM) quantifies the macroscopic conditions for the onset of self-sustaining chemical reactions. The threshold is an important theoretical and practical measure of material ...
Analysis of Unburned Methane Emission Mechanisms in Large-Bore Natural Gas Engines With Prechamber Ignition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although precombustion chambers, or prechambers, have long been employed for improving large-bore two-stroke natural gas engine ignition and combustion stability, their design predates modern analysis techniques. Employing ...
Operation of a Spark Ignition Engine With High Compression Ratio Using Biogas Blended With Natural Gas, Propane, and Hydrogen
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research evaluated the operational conditions for a diesel engine with high compression ratio (CR) converted to spark ignition (SI), under stable combustion conditions close to the knocking threshold. The main fuel ...
Characterization of Crankcase Ventilation Gas on Stationary Natural Gas Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural gas stands out as a prominent alternative fuel, boasting a well-established infrastructure for extraction and transport, substantial cost advantages, and potential for mitigating greenhouse gas (GHG) emissions. Its ...
