“…Figure 18 shows the NOx emission trend with respect to the applied load with and without a trap. The obtained trend clearly indicates that NO x emission increases linearly with the applied load 34,35 . The core reason is that as the load increases the in‐cylinder temperature also raises, which leads to an increase in NOx emissions 36 .…”

Carbon dioxide (CO2) is considered as a major contributor to global warming. Automobile contributes to around 65% of total carbon dioxide emissions globally when compared with other sources. On considering the upcoming stringent emission norms, this problem needs to be addressed properly. In this proposed study, an attempt is made to capture CO2 and other emissions from spark ignition engines using activated carbon as an adsorbent. In the initial part of this study, a numerical investigation on backpressure was carried out by varying the porosity factor of activated carbon. Computational analysis is carried out by placing activated carbon at three different variations. It is done by varying three different porosity percentages 30, 35, and 45 by placing activated carbon at three different locations. The final study reveals that activated carbon placed at the PC 35‐3 layout shows optimum backpressure and high filtration efficiency when compared with the other two layouts. Then, the PC35‐3 layout is fabricated and tested on a three‐cylinder, carburetted, variable speed, water‐cooled petrol engine at various load conditions (0%, 25%, 50%, 75%, and 100%.). Final results show that considerable amount of hydrocarbon, carbon monoxide, and CO2 gets reduced while operating the engine at idle and part load conditions and reduced exhaust gas temperature.

“…At low load condition, the untreated CO emissions originating from the exhaust gases are lower for CP20D80 than AA20D80 and diesel fuel by an average of about 16.67% at all PIT and PIM. The primary reason for the low CO emissions for CP20D80 can be attributed to the oxygenated nature of the fuel which still facilitates e cient combustion even after the depletion of intake oxygen in the air fuel mixture during main injection period (Solomon et al 2020). Similarly, the reason for the increase for AA20D80 can be due to the reduction of in-cylinder temperature in the expansion stroke which is further exacerbated by the higher latent heat of vaporization that results in a quenching effect and cause the incomplete combustion.…”

The rapid deterioration of the atmospheric air quality due to the rise in vehicular emissions is a cause for concern in a global scale. Hence, it is crucial to establish efficient control measures to mitigate these crises. In this context, the objective of this study is to explore the effect of post injection parameters on a continuous active regeneration trap (CART) to mitigate harmful greenhouse gases (GHG) and particulate smoke emissions (PSE) using diesel fuel reformulated by long-chain microalgae bio-alcohol and low – density microalgae biodiesel. Furthermore, the efficiency of the CART unit is analyzed based on its ability to mitigate the harmful emissions without sacrificing the engine performance characteristics. From the study, it was observed that the maximum de-smoke efficiency of 67.85% is observed at a post injection timing (PIT) of 20°CA aTDC at a post injection mass (PIM) of 4 mg for low load condition while operating on microalgae biodiesel. While operating on microalgae bio-alcohol, the maximum de-smoke CART efficiency was observed as 67.25% and 55.78% for low and medium load conditions at a PIT and PIM of 20°CA aTDC and 2 mg while operating on the microalgae bio-alcohol. Likewise, the maximum de-HC CART efficiency was obtained at a PIT and PIM of 10°CA aTDC and 1 mg with a reduction of about 75% and 73.8% for medium and high load conditions. A slight reduction in oxides of nitrogen with the complete elimination of carbon monoxide emissions is observed after CART treatment for both the fuels.
