“…Among all blend, D85B5E10 blend operation introduces more NOx emission which is shown in Zone C. In Figure 7(a)-7(c) the trade-off study of NOx-UHC-BTE at three different brake power has been shown. It can be easily explained that ternary blend with 10% ethanol fraction is more prone in formation of NOx and UHC emissions which is shown in Zone D. Similar type of comprehensive idea have been illustrated by Majumder et al [28] for performance-emission trade-off at a time. It has been clearly noticed from Figure 7(a) that D70B25E5 performs better in the highest reduction in UHC emission whereas D80B10E10 shows maximum NOx emission.…”

The issue of environmental pollution and the depletion of fossil fuel are nowadays a major field of attention for the modern world. In substitution of petroleum-based diesel, biodiesel and ethanol have been explored in many studies. In this paper, diesel-palm biodiesel-ethanol has been used together at different proportion to execute performanceemission characteristics and their trade-off study at different brake power. An experimental investigation is carried out for different diesel-palm biodiesel-ethanol blends ranging by volume of 5-10% ethanol, 5-25% biodiesel and 65-90% baseline diesel. From the experimental results, comparatively, low brake specific fuel consumption (BSEC) has been observed for all 5% ethanol-blended fuels. Maximum reduction in BSEC has been observed 1.9, 2, and 3.24 % at 0.68, 2.05, and 3.42 kW respectively. At medium to high load, brake thermal efficiency (BTE) has been found higher for lower ethanol fraction. As compared to diesel, the highest nitrogen oxide (NOx) reduction have been found 13.7, 9.17, and 4.7 % at 0.68, 2.05, and 3.42 kW respectively. At last, performance-emission trade-off shows that D70B25E5 blend has a higher BTE with maximum reduction in unburnt hydrocarbon (UHC) and NOx emissions.

“…Karthickeyan 30,31 tested a TBC diesel engine fueled with neem oil methyl ester (NOME) blends of 25% and 50% diesel. According to the research, engine components such as piston heads, cylinder heads, and valves were coated with bond coat NiCrAl thicknesses of 50 and 450 m, respectively, using plasma spray coating technology.…”

The novelty of this research work deals with green synthesized nanoadditives (5% of graphene, carbon nanotubes, and carbon black), oxygenated additives (5% of n‐butanol, n‐heptane, and n‐pentanol), and then the test fuels are prepared by blending of 20% of soybean biodiesel and 70%, 80%, and 100% of premium diesel. The experimental outcomes revealed that the Nickel Chromium Aluminum (NiCrAl‐120 micron), partially stabilized zirconia, and titanium dioxide ceramic composites at about 400 microns achieve the thermal barrier coat of low heat rejection (LHR) engine parts by the air‐plasma spray method. Compared with Blend B, green synthesized carbon black (5%), premium diesel (70%), and n‐pentanol (5%) mixed soybean biodiesel (20%) fuel (Blend E) tested on the LHR engine achieved 4.90% higher brake thermal efficiency and 25.31% lower brake‐specific fuel consumption at peak load owing to the presence of an oxygenated agent (n‐pentanol) in the fuel blend, which minimizes carbon deposition. The carbon monoxide, hydrocarbon, NOx, and smoke emissions were reduced by 25.58%, 29.41%, 5.06%, and 7.75% when compared to Blend B at peak load. Then, the in‐cylinder pressure and heat release rate were found to be 4.52% and 8.87% higher for Blend E at peak load compared to Blend B. This was because the mix of oxygenated additive and carbon black bio‐based nanofuels made the combustion process go faster. These fuel blends were tested on LHR diesel engines at various load conditions.

“…Today, the particulate filter has become a standard device to reduce the PM emission of a diesel engine. 4 Recently, the fuel blends with a certain control strategy or the clean energy technology is popular, such as the diesel-alcohol ether blends, [5][6][7] the diesel-hydrogen blends, 8 the diesel-nature gas blends, 9 and the dieseloxygenates blends. 10 For example, in 2012, Lin et al 11 reduced the NOx and PM emissions by adding a watercontaining butanol into a diesel engine.…”

Approximate dynamic programming is an effective optimal control method. This article researches a data-driven approximate dynamic programming. The method is extended to a nonlinear multi-input multi-output form. Using the data from a unique 4JB1-T weifu accumulator pump system (WAPS) engine, the developed approximate dynamic programming controller is trained to achieve its optimal trade-off emission control between the nitrogen oxides and particulate matter. The convergent proof of this method is given. The second-order training algorithm is introduced to promote the robust and convergent performance. The control objective is to let the WAPS engine pass the China State-IV emission test under the New European Drive Cycle. The bench test shows that an excellent control transient performance and significant promotion have been achieved. This article presents a new approach for the engine control and calibration. In addition, it also adds another dimension to the existing literature on the data-driven nonlinear multi-input multi-output trade-off emission control of the WAPS engine.
