Knock combustion is one of the primary factors limiting thermal efficiency improvement in
spark ignition (SI) engines. After a century of research, scholars have made significant …

Abstract Compressed Natural Gas (CNG) appears as a midterm solution to conventional
fuels, such as gasoline and diesel. The low carbon content and the possibility of being …

In this paper, a computational study was performed using a combination of several
numerical tools to better understand the limiting aspects of combustion in a passive pre …

Cyclic variations in conventional diesel combustion engines can lead to large differences in
engine out emissions even at steady operation. This study uses an optically accessible …

Experimental results from a study on the evolution of gas jets ejected through the orifices of
a pre-chamber in a heavy-duty optical engine are presented. The work examines conditions …

The cycle-to-cycle variation in the knock intensity is commonly encountered under abnormal
combustion conditions. The severity of these abnormal combustion events can vary …

This paper presents an experimental and numerical investigation of a spark-ignited (SI)
cooperative fuel research (CFR) engine fueled with different liquefied petroleum gas (LPG) …

Pretreating natural gas using catalytic oxidative coupling of methane (OCM) produces
ethylene and ethane, both species that increase fuel reactivity, thus increasing the potential …

Engine knock remains one of the major barriers to further improvement in thermal efficiency
of Direct-Injection Spark-Ignition (DISI) engines. While Research Octane Number and Motor …

This paper investigates the performance of hydrogen-fueled, spark-ignited, single-cylinder
Cooperative Fuel Research using experimental and numerical approaches. This study …
