“…In particular, it was found that NOx emissions decreased with increasing hole diameters. The same data for another engine can be found in [7,18,41]. The effect of the hole diameter on the smoke of the exhaust gases does not have a pronounced tendency (there is a complex regularity characteristic of this type of engine).…”

Reducing harmful emissions from exhaust gases and increasing energy efficiency are urgent tasks when designing reciprocating internal combustion engines. In this experimental work, the fuel system of a diesel locomotive engine operating on the Miller cycle is improved. The purpose of the study is to improve the environmental and economic indicators of diesel engines at minimal financial cost. The article provides an overview of the main research on improving fuel supply, mixing and combustion. The features of engine operation are also briefly described. Numerical simulation of the diesel engine operating cycle was performed before the bench tests. The experiments were performed on a full-size diesel engine with a power of 1200 kW. The measuring equipment and experimental technique are described in the article. The technical solutions that made it possible to improve the fuel supply are described. A new design for the high-pressure fuel pump drive is proposed. The optimal fuel injection advance angles are determined. An original design for the fuel pump plunger was developed. The proposed technical solutions made it possible to reduce fuel consumption by up to 3% (from 217.8 to 211.4 g/kW·h) and NOx emissions two-fold (from 19.4 to 8.8 g/kW·h).

“…The test results indicated a reduction in ignition latency and soot emissions. With the addition of the nano adjuvant, the oxidation rate increased. − Moreover, another researcher investigated a diesel engine’s performance and exhaust emission employing Jatropha methyl ester emulsions using alumina nanoparticles and carbon nanotubes as an additive. The results indicated an increase in the thermal efficiency of the brakes and a decrease in exhaust gases. − …”

This work reviews the numerous key parameters of each alcohol and their effect on CI engine characteristics. The second part of the review emphasizes the effect of nanoadditive addition on diesel and biodiesel owing to their physical and chemical features. A more detailed evaluation of the influence of nanoadditives on diesel engine behavior was done when diesel and biodiesel were doped at varying doses. According to the review, alcohols with a greater carbon concentration, such as butanol and pentanol, have superior miscibility and stability versus alcohols with lesser carbon elements. Additionally, the lower cooling impact and autoignition capability generated by high-alcohol concentrations would make this the optimum additive formulation for usage with diesel fuel. Nanoparticles have been added to fuels used in diesel engines to improve performance and reduce emissions in recent years. The utilization and preparation of fossil-based fuels increase environmental-related issues. Different nanomaterials assorted with fuels for compression ignition (CI) engines and their effects are reviewed in this work. Nanomaterials added to pure diesel and blends of diesel and biodiesel are considered for the study. The physiochemical properties of different fuels with nanoadditives are summarized. Performance characteristics such as brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), and exhaust gas temperature (EGT) are analyzed and compared for various fuel and nanoadditives combinations. Combustion characteristics and mass fraction burned are investigated. The values of various emissions from the engines fuelled with different combinations are examined. Among the various fuels and nanoadditives studied, 100 ppm TiO2 added diesel consumes the lowest BSFC of 0.3 kg/kWh. Hurdles faced in the current utilization of nanoadditives in diesel engines and the scope for future research are also highlighted.

“…Here it is worth mentioning that the use of biodiesel made from Linseed oil and mixed with nanoparticles reduced the carbon monoxide, smoke, and hydrocarbon emission but it increased the emission of nitrogenous oxides. 15 On a sixV921A diesel engine, Schumacher et al 16 investigated mixes of 10%, 20%, 30%, and 40% soya bean/diesel fuel. The heavy-duty engine test cycle developed by the U.S. Environmental Protection Agency (EPA) was used in this experiment.…”

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.
