“…Figure 7 presents the cumulative heat release (CHR) values obtained for each fuel used within the scope of the experimental study. Cumulative heat release (CHR) expresses the change in the heat released per crankshaft as a result of the combustion of the air/fuel ratio taken into the combustion chamber [53], [54]. The highest CHR value obtained in experimental studies was 374 J with D100 fuel at an engine load of 300 W. CHR value decreased with the increasing engine load.…”

In recent years, there have been many studies on the widespread use of liquid fuels derived from biomass. A common emphasis in such studies is on fewer exhaust gas emissions and the expansion of renewable fuel production. Biodiesel is considered to be an important type of biomass fuel that is already produced commercially. But the production of biodiesel is laborious and comprises combination of several chemical processes. This study examines the effects of using oil used in biodiesel production with oxygen-rich chemicals on combustion (in-cylinder pressure (Cp), heat release rate (HRR), rate of pressure rise (RoPR), and cumulative heat release (CHR)), exhaust emission values, energy and exergy analysis. In this study, the effects of butyl di glycol use were also investigated and compared with commercially used ethanol and n-butanol. A transesterification method produced from canola oil the biodiesel used in the experiments. The experimental fuels were mixed volumetrically. For this purpose, experiments were carried out with canola biodiesel produced at 20% (D80B20) in diesel fuel and the results of the experiments were recorded. Under the same conditions, experiments were carried out by adding ethanol (D60C20E20), n-butanol (D60C20B20), butyl di glycol (D60C20G20) at a rate of 20% by volume to the canola oil added to the diesel fuel. The lowest values in terms of thermal and exergy efficiency were obtained in D60C20G20 fuel at all engine loads. Also, the highest entropy generation was calculated at all engine loads for this fuel blend.

“…Air intake is considerably lower at lower load conditions compared to higher load conditions, which led to higher CO emission. The introduction of the high EGR percentage resulted in an increase in CO emission [19]. The reaction speed, O2 concentration, and in-cylinder temperature were all found to be reduced as the EGR rate was raised.…”

Rapid depletion of fossil fuels required the development of alternate and sustainable fuel sources that could replace conventional fuel while having no negative environmental impact. One of the best alternatives to conventional fuels that ensures strict emission standards and lowers energy usage is hydrogen induction combined with biodiesel. In this study, the performance, emissions, and combustion of a CI engine for Syzygium cumini (B20) were assessed and compared to diesel fuel while using a fixed amount of hydrogen flow rate (6L/m). Throughout the experiment, an exhaust gas recirculation (EGR) technology of 10% and 20% and a constant engine speed of 1500 rpm at varying engine load circumstances were used. When hydrogen is added to B20, it increases the emissions of carbon monoxide (CO), unburned hydrocarbons (UHC), brake thermal efficiency (BTE), and brake specific energy consumption (BSEC). At maximum load, the use of the EGR system decreased the exhaust gas temperature (EGT) by 13.4% and nitrogen oxide (NOX) emission by 25%, but it had a negative impact on BTE, BSEC, as well as other emission parameters including CO and UHC. Therefore, using hydrogen in dual fuel mode in a CI engine enhances performance and lowers exhaust emissions, while using the EGR approach reduces NOX emissions.

“…Hence higher NOx levels were exhausted when the combustion is taking place at increased combustion temperatures in the flame zone. Injection of hydrogen increases the combustion temperature attributed to its higher burning speed facilitating enhanced flame propagation during the burning process [47]. Further, at 60 • CA injection duration, the hydrogen gets sufficient time to mix with air, leading to a more homogeneous mixture.…”

“…Energies 2020, 13 This section highlights the various burning factors such as ID, CD, peak pressure, HRR associated with METP-hydrogen operated dual-fuel engine with ECU controlled hydrogen using both manifold and port injection methods. Injection of hydrogen plays a significant role in the combustion behavior as compared to when the same was inducted [47]. Figure 15 shows the ignition delay of a modified dual-fuel engine fueled with diesel/METP-hydrogen operation in which diesel and METP were injected using both CMFIS.…”

The present work is mapped to scrutinize the consequence of biodiesel and gaseous fuel properties, and their impact on compression-ignition (CI) engine combustion and emission characteristics in single and dual fuel operation. Biodiesel prepared from non-edible oil source derived from Thevetia peruviana belonging to the plant family of Apocynaceaeis. The fuel has been referred as methyl ester of Thevetia peruviana (METP) and adopted as pilot fuel for the effective combustion of compressed gaseous fuel of hydrogen. This investigation is an effort to augment the engine performance of a biodiesel-gaseous fueled diesel engine operated under varied engine parameters. Subsequently, consequences of gas flow rate, injection timing, gas entry type, and manifold gas injection on the modified dual-fuel engine using conventional mechanical fuel injections (CMFIS) for optimum engine performance were investigated. Fuel consumption, CO, UHC, and smoke formations are spotted to be less besides higher NOx emissions compared to CMFIS operation. The fuel burning features such as ignition delay, burning interval, and variation of pressure and heat release rates with crank angle are scrutinized and compared with base fuel. Sustained research in this direction can convey practical engine technology, concerning fuel combinations in the dual fuel mode, paving the way to alternatives which counter the continued fossil fuel utilization that has detrimental impacts on the climate.
