Oxy‐fuel combustion for carbon capture and storage in internal combustion engines – A review

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 (CO 2 ) 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.

Exploring the potential benefits of Ethanol Direct Injection (EDI) timing and pressure on particulate emission characteristics in a Dual-Fuel Spark Ignition (DFSI) engine

“…It can be observed that every 𝑁𝑁 𝑃𝑃 curve presents an approximate unimodal distribution with a peak located around 17 nm nucleation mode. Furthermore, by increasing 𝑃𝑃 𝐼𝐼 from 5.5 MPa to 18 MPa, the peak of 𝑁𝑁 𝑃𝑃 curve gradually reduces from 9.83×10 5 to 4.66×10 5 . Regarding the trend of 𝑀𝑀 𝑃𝑃 , it demonstrates that increasing 𝑃𝑃 𝐼𝐼 has a positive effect on 𝑀𝑀 𝑃𝑃 reduction, but the benefit is not very obvious.…”

“…It can be seen that the 𝑁𝑁 𝑃𝑃 size distribution is quite sensitive to 𝑡𝑡 𝐼𝐼 . With 𝑡𝑡 𝐼𝐼 from -340 ºCA to -320 ºCA, the peak of curve for nucleation mode decreases from 1.27×10 6 to 8.36×10 5 , whilst the peak of accumulation mode decreases from 1.48×10 6 to 6.45×10 5 . By delaying 𝑡𝑡 𝐼𝐼 to -300 ºCA, the curve changes from bimodal to unimodal.…”

“…One of the major pollutants is particulate matter emitted by vehicles, which would adversely affect regional air quality, climate change and human health, particularly cardiorespiratory diseases [1]. Currently, some novel vehicle powertrain technologies without Internal Combustion Engine (ICE) have been developed to reduce engine emissions, such as Battery Electric Vehicle (BEV) [2], Fuel Cell Electric Vehicle (FCEV) [3] [4], Oxy-Fuel Combustion-Carbon Capture and Storage (OFC-CCS) system [5].…”

Oxyfuel Combustion in IC Engines

“…As Net Zero Carbon Emissions strategy has been implemented in some countries and will be implemented gradually throughout the world, various zero carbon technologies are being developed, such as pure Battery Electric Vehicle (BEV) and Fuel Cell Vehicle (FCV) that have achieved certain mass production, although they have a high price and low driving range. For considering heavy-duty applications and with an alternative technology for a low-cost operation, hydrogen combustion technology and CCS (Carbon Capture and Storage) technology for hydrocarbon combustion are being developed widely [1].…”

“…Nevertheless, these technologies are too expensive and their output torque is low to be widely applied to heavy-duty engines used in waterway transportation. [22][23].…”
