“…Moreover, similar findings for biogas-diesel fuel operations were reported by other researchers [29,46,53]. Most of the studies [19,32,54] confirm that the use of biogas increases BSFCs due to their lower energy density and the presence of CO2. Figure 7 illustrates the EGT for diesel and biogas-diesel fuel operations.…”

“…Moreover the presence higher ratio of CO2 in biogas absorbs some of the heat from the combustion reaction hence the EGT for the biogas with higher CO2 percentages decreases [56]. Similar decreases in exhaust gas temperatures for biogas-diesel fuels were reported by Barik and Muragan et al [29], Duc et al [51], Barik et al [46], and Rosha et al [54]. Figure 8a,b shows the cylinder pressure as a function of crank angle for diesel and biogas-diesel.…”

In recent years, due to stringent emission regulations vehicle manufacturers have been compelled to cut down noxious pollutants released from diesel engines. Different alternative solutions have been recommended to achieve this challenging task. One of these alternative solutions is the utilization of biogas in addition to the use of liquid diesel. In this regard, the current study investigates the combustion characteristics and exhaust emissions of a turbocharged, direct injection, diesel engine operating at constant speed (1800 rpm) and under dual fuel mode with diesel as the pilot fuel and biogas (generated from pig manure and corn straw) and methane enriched biogas. Simulations were carried out at four various engine loads corresponding to brake mean effective pressure (BMEP) of 0.425, 0.85, 1.275, and 1.7 MPa using GT-Power package. The BTE values of biogas-diesel were higher as compared to diesel fuel. The CO2 ratio of biogas did not impact BTE considerably. The highest BTE value of 38.22% was recorded for BG45. However, the Brake specific fuel consumption (BSFC) values for the biogas-diesel fuels were higher than that of diesel fuel operations. With respect to emissions, compared to diesel fuel operation, the hydrocarbon (HC) and CO2 of the biogas-diesel were higher, but NOx and CO pollutants were much lower. The utilization of biogas with diesel by all accounts is attractive to cut down discharges and improve performance of the engine. The engine performance did not deteriorate with up to 45% CO2 proportion in biogas.

“…Under dual-fuel mode, this higher flame velocity of H 2 leads quick and complete oxidation of the charge (diesel-HEB-air), which further declines the HC emissions. 41 The recorded HC emissions were 21,19,18,17, and 16 ppm at 0.1, 0.2, 0.3, 0.4, and 0.5 kg/hr flow rates of HEB, respectively, at no load conditions. On the contrary, the NOx emissions increase with increasing bmep from 0 to 3.5 bar.…”

“…At higher bmep, the increment in HC emissions was due to oxygen deficiency (rich mixture zone). The HC emission values were measured to be 24,20,18,17,19, and 26 ppm at 0, 0.7, 1.4, 2.1, 2.8, and 3.5 bar bmep, respectively, for diesel fuel. With the injection of HEB (gaseous fuel), it was seen that HC emission decreases.…”

“…15 Continuous injection of H 2 in CI engine may also cause combustion challenges, including backfiring, preignition, and engine knocking. 16 Utilization of various gaseous fuels in CI engine has been thoroughly reviewed by Rosha et al 17 It was found that the attained temperature during compression stroke is not sufficient for starting combustion process in H 2 -based CI engines. These engines offer reduced carbon-based emissions because H 2 has zero carbon content.…”

Gaseous fuel induction in a compression ignition (CI) engine has picked up much attention over the most recent few years, particularly when it is produced by using renewable sources. In this study, hydrogen-enriched biogas (HEB) was used as a gaseous fuel and co-combusted in dual-fuel CI engine.Experimentation was carried out on a 3.5-kW CI engine test rig in the brake mean effective pressure range between 0 and 3.5 bar, as well as, HEB between 0.1 and 0.5 kg/hr. HEB induction effects on various engine characteristics (combustion, performance, and emission) were studied at rated engine speed (1,500 rpm). Results revealed that the peak cylinder pressure and ignition delay period increased with increasing HEB proportion (0.1 to 0.5 kg/hr) as compared with diesel mode. The calorific value of HEB (57.0 MJ/kg) is higher than diesel (42.0 MJ/kg), which led to improved BTE in dual-fuel mode. The emission results showed that with an increase of HEB rates, the NOx emission mildly decreases, but smoke opacity and hydrocarbon emissions majorly reduce. Thus, the HEB induction has great potential to be a feasible technological solution to overcome low BTE and high hydrocarbon emissions in biogas operated CI engines.

Hydrocarbon reforming route has gained immense attention for producing energy‐effective renewable fuels and/or chemicals in the recent era. In this simulation study, O2 addition and CH4 recycling's effect on the dry oxidative reforming reactor's performance was investigated. Aspen HYSYS simulation software was used to assess a biogas‐to‐syngas conversion process's feasibility by integrating with the CH4 recycling loop and CO2 sequestration in a dry oxidative reforming process. Simulation runs were performed by varying the O2/CH4 ratio content from 0 to 0.20 and temperature (450 to 700°C). Results illustrated that CH4 conversion improved by re‐injecting of unreacted CH4, followed by CO2 sequestration to a great extent. In dry oxidative reforming, at stoichiometry O2/CH4 ratio of 0.17, CH4 conversion (21.7%), and CO2 conversion (3.3%) were obtained at 500°C, with 1.2 H2/CO ratio. Further, 0.308 kg mole/h of H2 could be produced with biogas (1.0 kg mole/h) at optimal parameters 500°C (temperature) and 0.17 (O2/CH4 ratio) by using recycling loop in one cycle. Thus, dry oxidative reforming coupled with the CH4 recycling unit provides a better option for syngas/H2 production and remarkably addresses high energy demand in the dry reforming process.
