“…It is necessary to perform the uncertainty analysis to minimize the systematic errors of the experimental data from the measuring instrument 35 . The analysis helps to (i) avoid the errors at different working conditions, (ii) avoid the improper calibration of the instrument, (iii) avoid the error and inaccuracy of measuring instrument, and (iv) avoid the improper planning of experiments, and some man‐made errors 36 . The different measured variables are considered in multiple experiments carried out in the test engine to determine the unaccounted uncertainties results.…”

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.

An unpredictable rise in greenhouse gas (GHG) emissions is a primary concern to the global scientific community. It is directly related to the rapid expansion of the human population and associated with the immense energy demand. The combustion of hydrocarbon fuels in internal combustion (IC) engines releases a large amount of carbon dioxide (CO2), which is one of the causes of GHG emissions. Mitigation of CO2 emissions is a significant challenge to the world. Although several researchers have focused on capturing CO2 from power plants, some researchers have taken initiatives in recent times to capture CO2 in IC engines. This study particularly explored the possibility of using a biomass based‐adsorbent to capture CO2 in the exhaust of a diesel engine. Initially, activated carbon was obtained from palm shells by adopting the preparation methods such as (i) carbonization and (ii) chemical activation. Then, the produced activated carbon was analyzed to examine its physicochemical characteristics and surface textural properties by adopting characterization techniques. The adsorbent sample was loaded in an in‐house fabricated adsorption chamber which was attached to the exhaust of a single‐cylinder, four‐stroke, naturally aspirated, air‐cooled, direct injection (DI), constant speed diesel test engine. The performance of palm shell‐based activated carbon was evaluated as a potential adsorbent for CO2 capture when the engine was operated with two distinct fuels, (i) 100% diesel (D100) and (ii) an optimum biodiesel‐diesel blend (JME20) comprising 80% D100 and 20% Jatropha Methyl Ester (JME). The experimental results showed that an average of about 30% and 37% of CO2 was captured by using palm shell‐based adsorbent in D100 and JME 20 operations, respectively.

The continuous depletion of conventional fuels requires urgent research work to identify feasible alternative fuels to meet the minimum environmental impact of sustainable energy demand. Due to good combustion characteristics, acetylene being one of such alternative fuel and has the potential to be a future fuel. In this concern, it was decided to perform experimentation on a stationary water‐cooled spark ignition (S.I.) engine in acetylene‐gasolinedual fuel mode. In this experimental investigation, the effects of acetylene and gasoline mixtures on the performance, emissions, and combustion characteristics have been observed. Acetylene was supplied through a modified engine intake manifold at optimized conditions for petrol. The optimum flow rate of acetylene was found by comparing the performance and emissions for 50, 100, and 150 LPH, respectively, at 1600 revolution per minute (rpm). The experimental results showed that the brake thermal efficiency at 100 LPH was the highest amongst all the flow rates under study, throughout the load range in acetylene‐gasoline dual fuel mode. HC, CO, and CO2 emissions for this acetylene flow rate were either low or comparable to that of pure gasoline. Based on this study, it can be concluded that use of acetylene in S.I. engine without any major modifications is feasible without having any adverse effect on the engine performance, combustion, and emissions.
