“…Feroskhan and Ismail [77] used simulated biogas and reported that methane enrichment will enhance the brake thermal efficiency at low biogas flow rates. Mustafi et al [64] also observed that the brake specific energy consumption of the biogas-diesel dual fuel and diesel-only modes was nearly the same. Sorathia and Yadav [78] also reported almost no deterioration in brake thermal efficiency in a CI engine operated in dual fuel mode with diesel and biogas.…”

“…Studies on an IDI engine with biogas in dual fuel mode with diesel substitution up to 48% indicated a reduction in combustion duration and consequently lower exhaust gas temperatures [58]. In a study involving biogas-diesel dual fuel operation, the maximum Net Heat Release Rate (NHRR) was observed to be around 30% greater for the dual fuel mode compared to diesel-only mode under similar loading and speed conditions [64]. The increase in ID can be offset by using higher quantity of pilot fuel.…”

“…However, this causes a notable increase in CO2 and NOx emissions [31]. The extent of variation of these parameters can be controlled by adjusting the pilot diesel injection quantity [64,65]. Barik and Murugan [33] observed that a biogas flow rate of 0.9 kg/h provided the optimum combination of performance and emissions.…”

“…The effects of injection timing, intake charge temperature, and biogas energy ratio were studied. The best injection timing, intake charge temperature, and biogas energy ratio were found to be [55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70] o BTDC, 50 -90 o C. and 80%, respectively. By advancing the diesel injection timing, the homogeneity of the lean mixtures was enhanced.…”

Biogas is commonly produced during the decay of organic matter. It is a mixture of methane and some non-combustible gases such as CO2 and H2S. Its viability as a renewable alternative fuel for internal combustion engines can be enhanced by methane enrichment, i.e. removal of the non-combustible constituents. One of the common techniques for using biogas in a compression ignition (CI) engine is to mix it with air in the intake manifold, induct, and compress this mixture and ignite it by injecting a small quantity of diesel or bio-diesel, which is termed as the pilot fuel. This is known as the dual fuel mode. The pilot fuel is injected close to the end of the compression stroke as in a conventional CI engine and the injected fuel quantity depends on the operating condition. An alternative approach is the Homogeneous Charged Compression Ignition (HCCI) mode. Here, a homogeneous mixture of biogas and air is inducted and compressed by the piston until it auto-ignites. While this concept combines the benefits of spark ignition (SI) and CI engines, the onset of combustion cannot be controlled directly. A detailed review of recent research pertaining to biogas purification techniques and operation of CI engines with biogas in dual fuel and HCCI modes is presented in this paper. The effects of various operating parameters on engine performance and emissions, and comparison with conventional diesel fuelled CI engines are discussed. Biogas improves combustion efficiency, NOx, and smoke emissions. However, it reduces brake thermal efficiency, volumetric efficiency, and increases HC and CO emissions. Biogas fuelling of CI engines is recommended for achieving high diesel substitution, especially under high torque operation.

“…This trend could be ascribed to the methane presence that lowers the temperature in the chamber thus inhibiting the diesel ignition in DF operation. The longer diesel ignition delay in DF mode could also be ascribed to chemical factors: the methane mixed with air, in fact, alters the properties of the charge, the oxygen concentration and the pre-ignition reaction activities during compression [11].…”

Methane represents an attractive energy source for power production generated by internal combustion engines because of its renewable nature and environmental friendly characteristics. The most suitable way to utilize methane in compression ignition engines is the dual fuel (DF) technology. In diesel/methane DF operation the gas is injected into the intake manifold to mix uniformly with air; the premixed air-methane mixture is drawn into the cylinder and it is ignited by diesel fuel injected directly in the chamber. This paper deals with the energetic potentiality of a small compression ignition engine modified to run in diesel/methane DF mode. The engine is a three-cylinder, 1.0 L, equipped with a common rail injection system. Experiments were performed at different speeds and loads. For each operating condition, a part of the total energy was supplied by the diesel combustion and the remaining by methane. Combustion process was analyzed by incylinder pressure signal. Optical diagnostics were applied to investigate the effect of methane addiction to diesel fuel on combustion evolution and pollutant formation. Pollutant emissions were measured at exhaust. It was found out that DF operation represents a feasible way to reduce both particulate matter and nitrogen oxides emissions.

Economic and environmental concerns have driven biofuel research in the last few decades. In order to this, biogas production is being encouraged on a worldwide scale to reduce carbon emissions and increase resource recovery from diversified wastes. The present contribution involves finding the best way to turn food waste and animal manure into biogas and its effective utilization in a dual‐fuel mode diesel engine. For the experimentation, a Taguchi approach was used to develop an L25 orthogonal array with three factors and five levels of parameters: cattle dung and food waste ratios, retention times, and digester temperatures. Using the response surface method (RSM), genetic algorithm (GA), and cuckoo search algorithm (CSA), the biogas yield was optimized and compared to get the best optimization technique. Based on the specific goals of the study, GA is the best combination of parameters for producing biogas. The optimal condition for producing biogas was a cattle dung and food waste ratio of 0:100 (wt/wt %) with a retention time of 15 days and a digester temperature of 40°C, and the corresponding value of the biogas yield was 551.633 mL/day. Experiments were done to confirm this prediction. This study also intends to determine the viability of ternary fuel blends (microalgae biodiesel, n‐butanol additive, and diesel) as a pilot fuel and biogas as a primary fuel by changing their mass flow rates (0.5, 1.0, and 1.5 kg/h) in the CI engine. The D70BD20Bu10 ternary fuel blend with 1.5 kg/h of biogas flow rate was found to be an optimum blend due to its improved performance and emission characteristics compared to other tested fuels. This fuel blending improves brake thermal efficiency (BTE) by 6.25% and reduces brake‐specific fuel consumption (BSFC) by 2.14%. NOx and smoke emissions were both reduced by 58.22% and 54.59%, respectively. However, HC and CO emissions were on the higher side compared to diesel.
