Abstract

As the impacts of global warming have become increasingly severe, oxy-fuel
combustion has been widely considered a promising solution for carbon capture
and storage (CCS) to reduce carbon dioxide (CO2) to achieve net-zero
emissions. In the past few decades, researchers around the world have demonstrated
improvements by the application of oxy-fuel combustion to internal
combustion (IC) engines. This article presents a comprehensive review of the
experimental and simulation studies about oxy-combustion for CCS in IC
engines. To give a more comprehensive understanding, it has included a
detailed explanation of the essential components contained in an oxy-fuel IC
engine and its typical operating parameters. The oxy-fuel IC engine components
include the system of oxygen supply, exhaust gas recirculation (EGR),
water injection, fuel injection, and CCS. In order to optimise the combustion
process, it is required to adopt the appropriate values for the oxygen concentration,
EGR rate, ignition timing, compression ratio, fuel injection, and water
injection in oxy-fuel engines. The detailed literature review and analysis presented
provide a basis for the selection of oxy-fuel combustion for CCS as a prospective
solution to reduce carbon emissions in IC engines.
