“…It is found that the blend of KOME-Orange oil + 20 % n-butanol is used as a bio-fuel with Zeolite-based non-selective catalytic reduction (NSCR) adsorbent reduces CO2, smoke and NO emissions by about 15 %, 19 % and 41 %, respectively. Sameer et al [10] used the adsorbent to mitigate CO2 from a diesel engine system. They used Zinc Chloride (ZnCl2) as a potential activator to produce an efficient adsorbent.…”

Carbon dioxide (CO2) is one of the primary greenhouse gases (GHGs), which is responsible for global warming potential (GWP) and climate change. The automotive industry is responsible for more than 60 % of CO2 emissions compared to other sources worldwide. The appropriate treatment is required to curb emissions in deep concern for future generations. This study uses activated carbon as an adsorbent to mitigate CO2 and other pollutants from compression ignition (CI) engines. Initially, the porosity factor of activated carbon is employed to conduct a numerical analysis of back pressure in the capture unit. The packed activated carbon is placed in two distinct variants for computational analysis. It is performed by placing activated carbon in two positions to modify the porosity percentages from 25 to 50 at a regular interval of 5. The study shows that the activated carbon configuration exhibits allowable backpressure and excellent adsorption performance. Based on the permissible backpressure limit configuration, the capture unit is developed. The adsorbent is loaded inside the cylindrical arrangement of the capture unit and is attached to the compression ignition (CI) engine’s exhaust. The test engine is operated on diesel mode under various load circumstances with and without the capture unit. The experimental results showed that the simultaneous Carbon monoxide (CO) – carbon dioxide (CO2) – hydrocarbon (HC) – oxides of nitrogen (NOx) reduction is achieved by about 5.1 %, 24 %, 15 % and 18 %, respectively.

The atmospheric carbon dioxide (CO2) concentration has been consistently increasing each year throughout the world. Internal combustion (IC) engines are significant contributors to CO2 emissions. This study explores the possibility of employing effective biomass‐based adsorbents to mitigate CO2 from a diesel engine exhaust. As a first step, two distinct agro‐wastes, namely, i) corn cob and ii) sugarcane bagasse, are used to prepare inexpensive and efficient activated carbons. The two main steps in the activated carbon preparation are a) carbonization and b) activation. The derived activated carbons are subjected to discrete analytical techniques to examine their structural and textural characteristics, surface functional groups, and physical, chemical, and adsorptive properties. As a second step, the exhaust treatment chamber unit is filled with the adsorbents one by one and is connected to the exhaust of the constant pressure heat addition engine. A single‐cylinder, four‐stroke, naturally‐aspirated, air‐cooled, direct injection (DI) compression ignition (CI) engine is used in the experimental investigations. The essential findings show that ≈68 and 60% of CO2 emissions are adsorbed in the test engine by utilizing corn cob and sugarcane bagasse adsorbents, respectively. The results show that during the D100 and JME20 operations, the prospective adsorbents can curb more than 40% of overall CO2 emissions.

Mitigation of carbon dioxide (CO 2 ) from various sources is a major challenge in the world today. Apart from attempts to control CO 2 emissions from large CO 2 emitting sources such as coal-fired power plants and significant fossil fuel-consuming industries, there have also been attempts made to control CO 2 in internal combustion (IC) engines. Compression ignition (CI) engines find their applications mainly in automotive vehicles, decentralized power generation units, standby power requirements in hospitals and educational institutions. In recent years, there has been a great interest in developing eco-friendly and low-cost adsorbents for CO 2 capture via the adsorption method. This investigation explores the possibility of using activated carbon obtained from coconut shell for capturing CO 2 in a CI engine exhaust. Surface texture characteristics and physicochemical properties of the coconut shell-based activated carbon are determined for their suitability as a potential adsorbent for CO 2 adsorption. Furthermore, an attempt is made to combine a postcombustion carbon capture device in a CI engine. For this purpose, an in-house fabricated adsorption chamber is packed with activated carbon and attached to a single-cylinder, four-stroke, naturally aspirated, direct injection (DI) diesel engine exhaust. The test engine is operated on two different fuels; (i) diesel (D100) and (ii) biodiesel-diesel blend comprising 20% of Jatropha methyl ester (JME) and 80% of diesel (JME20). The engine performance and CO 2 emission without and with the adsorption chamber are evaluated for D100 and JME20 operations. Further, the performance parameters of the adsorption chamber packed with activated carbon are also evaluated in both fuel operations. The results are analyzed, discussed, and presented in this paper.
