“…From the higher EGT and NOx of the MOB, we observe that the MOB results in higher combustion temperature. The above results are similar to the results reported in the literature (Sahoo et al, 2009). …”

“…Researchers (Raheman and Ghadge, 2007;Puhan et al, 2005) have reported that the biodiesel derived from Mahua oil (MO) can be used as sole fuel or blends with diesel in diesel engines, with considerable reduction in CO, UBHC and smoke emissions and slightly higher NOx emission. From the literature (Monyem et al, 2001;Nwafor, 2005;Manieniyan and Sivaprakasam, 2008;Banapurmath et al, 2009;Sahoo et al, 2009), it is observed that injection timing is one of the variables which affect the performance and emissions of diesel engines. Hence in the present work, the injection timing was advanced and its effect on engine performance was studied.…”

Rising petroleum prices, an increasing threat to the environment from exhaust emissions, global warming and the threat of supply instabilities has led to the choice of inedible Mahua oil (MO) as one of the main alternative fuels to diesel oil in India. In the present work, MO was converted into biodiesel by transesterification using methanol and sodium hydroxide. The cost of Mahua oil biodiesel (MOB) is higher than diesel. Hence liquefied petroleum gas (LPG), which is one of the cheapest gaseous fuels available in India, was fumigated along with the air to reduce the operating cost and to reduce emissions. The dual fuel engine resulted in lower efficiency and higher emissions at part load. Hence in the present work, the injection time was varied and the performance of the dual fuel engine was studied. From the engine tests, it is observed that an advanced injection time results in higher efficiency and lower emissions. Hence, advancing the injection timing is one of the ways of increasing the efficiency of LPG+MOB dual fuel engine operated at part load.

“…However, for higher CO2 content, the dilution effect dominates and lowers the thermal efficiency. Sahoo, Sahoo, and Saha [79] reviewed various works dealing with dual fuel gas diesel engines. They confirmed that biogas containing up to 20-30% CO2 offers lower BSFC compared to diesel-natural gas operation, whereas BSFC increases with further increase in CO2 content on account of the inert gas effect.…”

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.

“…The viscosity of fuel must be checked and have to maintain to the closest limit of diesel fuel viscosity which is around 1.7-4.1 cSt at 40˚C [14]. Controlling the viscosity of fuel helps to provide a proper atomization of fuel during combustion [15] which leads to complete combustion and help the emission control due to incomplete combustion [16]. The density and viscosity of diesel-ethanol blends were said to decrease as the ethanol contents increase which proved by De Gang Li [17]as shown in Figure 1.…”

Abstract. Diesel engine is known as the most efficient engine with high efficiency and power but always reported as high fuel emission. Malaysia National Automotive Policy (NAP) was targeting to improve competitive regional focusing on green technology development in reducing the emission of the engine. Therefore, ethanol was introduced to reduce the emission of the engine and while increasing its performance, Palm methyl ester was introduced as blend enhancer to improve engine performance and improve diesel-ethanol blends stability. This paper aimed to study the characteristics of the blends and to prove the ability of palm-methyl-ester as co-solvent in ethanol-diesel blends. Stability and thermophysical test were carried out for different fuel compositions. The stability of dieselethanol blended was proved to be improved with the addition of PME at the longer period and the stability of the blends changed depending on temperature and ethanol content. Density and viscosity of diesel-ethanol-PME blends also give higher result than diesel-ethanol blends and it's proved that PME is able to increase density and viscosity of blends. Besides, heating value of the blends also increases with the increasing PME in diesel-ethanol blends.
