“…However, when the engine is loaded during half load, three-quarter load, or full-load conditions, the CO 2 emission increases gradually for all fuels tested. This is because of the higher availability of air inside the combustion chamber . Under full-load conditions, the availability of oxygen in the air, besides the oxygen in biofuel, leads to higher CO 2 emission compared to D100.…”

“…A premixed stratification charge involving early injection followed by charge introduction at TDC is recommended for reducing carbon-based emission . A solution is the use of biofuels containing oxygen, which isolates fuel-rich regions, enhances the combustion process, and reduces the formation of HC, CO, and soot. , Biofuels have the advantage of reduced viscosity and can be directly used in internal combustion (IC) engines without any amendment. However, in the presence of natural oxygen, biofuels have a higher combustion efficiency than diesel fuel, resulting in increased nitrogen oxide emissions.…”

The main aim of the study was to reduce carbon emissions in the atmosphere using a novel Andropogon narudus (AN) biofuel using higher air temperatures and reducing the consumption of conventional fossil fuel (diesel). The use of a heat exchange chamber within the air intake manifold is a popular method to reduce hydrocarbon (HC) and carbon monoxide (CO) emissions during cold starts. A premixed charged compression ignition engine in the dual-fuel mode was used in this study with raw diesel, raw AN oil, AN70+D30, AN80+D20, AN80+D20 (35 °C), AN80+D20 (40 °C), and AN80+D20 (45 °C). A chamber was designed and analyzed to measure the exit temperature and density change and to determine the reduction in volumetric efficiency of the engine, using Ansys Fluent software. A sustainability assessment study was performed to understand the feasibility of the fuel and the design using the Pugh Matrix. The fuel AN80+D20 with an air temperature of 45 °C was found to be superior to all other fuels in terms of brake thermal efficiency, reaching at 32.1%. D100 used the least amount of energy, whereas AN80+D20 used the most. Engine HC emission was at the lowest (45.01 ppm) for AN80+D20 fuel at 45 °C air input and reached the highest (50 ppm) for AN100 fuel. With an air temperature of 45 °C, CO emission was at its lowest for AN80+D20 gasoline (0.018%) and was at its highest for AN100 (0.072%). Nitrogen oxide emissions were the highest for AN80+D20 fuel with an air temperature of 45 °C, with an air concentration of 1254 ppm, whereas they were the lowest for AN100 (900 ppm). CO 2 values were reduced, with D100 showing the lowest levels and AN100 showing the highest. The smoke emission was minimum for AN80+D20 fuel at 45 °C, with a smoke number of 15 compared to 33 for D100 fuel. As per the Pugh Matrix assessment, AN80+D20 with 35 °C air temperature had higher scores compared to all of the other fuel mixtures.

Elumalai et al [56] examined the effect of high-volatile npentanol percentage on the performance, combustion, and emission characteristics of PCCI engines at 1500 rpm and 17.5 CR. The primary fuel used in the engine was a blend of 80% diesel fuel and 20% waste tire pyrolysis oil with injection timing of 35• BTDC, while the secondary fuel n-pentanol was sprayed into the intake manifold with varying percentages, namely 10%, 20%, and 30%.…”

As internal combustion engines (ICEs) produce serious emissions and a big part of greenhouse gases from fuel combustion. Due to the universal concerns about degradation in the ambient environment, limitations on exhaust emissions, depletion of petroleum reserves, and global warming, many strict regulations have been launched on the standard emissions released from engines. These challenges oblige engine researchers worldwide to develop a new strategic balance between engine performance and emissions. Premixed charge compression ignition (PCCI) is a promising technique to overcome these challenges in recent years which can simultaneously reduce NOx and soot emissions and substantially improve thermal efficiency. The PCCI combustion concept has the advantages of both SI and CI engines, like SI engines as the charge is premixed which produces low emissions and like CI engines the fuel-air mixture is auto-ignited as a result of compression which leads to high thermal efficiency. Normally, PCCI combustion is a single-stage combustion process achieved by employing early injection timing to increase the time available for mixing fuel and air by using single-fuel and split fuel (pilot/main) injection tactics, in which a large fraction of fuel burns in premixed combustion phase resulting in relatively lower in-cylinder temperatures compared to compression ignition (CI) combustion. Thus, the objective of this paper is to provide an inclusive review of the effects of fuel injection timings, ratios, pressure, and fuel properties on the PCCI engine combustion performance improvement and emission reduction, this review has been analyzed extensively based on the published studies to provide and discuss different strategies for the control of PCCI technique of combustion at a wide range of speed and load.

“…6 Reactivity based mixing of fuels and duel fuel mixing for using it in compression ignition engine has also been pursued at varied loads alongwith the use of nano-particles which showed a slight increase in the brake thermal efficiency coupled with a decrease in NOx production. [7][8][9] Biodiesel's high oxygen content, as compared to conventional diesel fuel, may improve full combustion, reducing unburned hydrocarbon, particulate matter, and carbon monoxide in diesel engines while increasing NOx emissions. 10 Methyl ester obtained from Chlorella emersonii (CEME) was used by Venu et al 11 for blending with diesel for fueling a single cylinder diesel engine and it resulted in increased levels of CO 2 and NOx emissions.…”

The sole objective of the current work is to assess the effects of adding waste plastic fuel to diesel and jatropha biodiesel. In order to test this, seven distinct fuel samples made up of jatropha biodiesel-diesel, WPF-jatropha biodiesel-diesel, and regular diesel as a reference fuel were created using predefined volumetric proportions. After thorough characterization, studies are carried out employing spectroscopic methods such as FTIR, elemental analysis, and GC-MS. Finally, a direct-injection single-cylinder diesel engine underwent performance and emission tests. It has been discovered that adding WPF to biodiesel lowers its density, flash point, and viscosity. When WPF is added to biodiesel blends, the biodiesel’s cold flow properties are improved, and its calorific value and diesel index are raised. According to FTIR analysis of the fuel samples, the WPF mixed biodiesel, biodiesel, and diesel all share certain common functional groups. According to GC-MS examination of the fuel samples, all of the blends contain some aliphatic and aromatic chemicals as well as diglycerides, triglycerides, and ester components. WPF blended fuels exhibit improved thermal efficiency under partial loading situations, according to engine performance tests. It is discovered that the WPF blended fuel has a lower exhaust temperature than biodiesel. Compared to biodiesel and diesel, WPF mixed fuel has higher HC emissions but lower NOx emissions. Thus, it is advantageous to mix waste plastic fuel with biodiesel because doing so lowers NOx emissions while simultaneously raising the calorific value and diesel index of the biodiesel.
