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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
