“…With an increase in DOP concentration, PM emissions reduced, except at 100% engine load where PM emissions from reference diesel and 90D10DOP were similar. This PM emission benefit from DOP blended fuel is well expected here since the reduction in PM emissions from oxygenated fuels is common in the literature [30].…”

Physico-chemical properties of microalgae biodiesel depend on the microalgae species and oil extraction method. Dioctyl phthalate (DOP) is a clear, colourless and viscous liquid as a plasticizer. It is used in the processing of polyvinyl chloride (PVC) resin and polymers. A new potential biofuel, hydrothermally liquefied microalgae bio-oil can contain nearly 11% (by mass) of DOP. This study investigated the feasibility of using up to 20% DOP blended in 80% diesel fuel (v/v) in an existing diesel engine, and assessed the performance and exhaust emissions. Despite reasonable differences in density, viscosity, surface tension, and boiling point, blends of DOP and diesel fuel were found to be entirely miscible and no separation was observed at any stage during prolonged miscibility tests. The engine test study found a slight decrease in peak cylinder pressure, brake, and indicated mean effective pressure, indicated power, brake power, and indicated and brake thermal efficiency with DOP blended fuels, where the specific fuel consumption increased. This is due to the presence of 16.4% oxygen in neat DOP, responsible for the relatively lower heating value, compared to that of diesel. The emission tests revealed a slight increase in nitrogen oxides (NOx) and carbon monoxide (CO) emissions from DOP blended fuels. However, particulate matter (PM) emissions were lower from DOP blended fuels, although some inconsistency in particle number (PN) was present among different engine loads.

“…The effects of biodiesel on these parameters depend on mainly the tested engine, the engine operating point as well as the test method. Decreasing and also increasing of particulate mass and number with biodiesel compared to conventional diesel can be noticed, in these reviews [9,11,16,17] as well.…”

“…According to [11], which also summarize the results of different studies aiming to measure the particle size distribution in the engine exhaust running on biodiesel and biodiesel blends inconsistent trends reveal in particle size distribution when the engine is fuelled with biodiesel or biodiesel-diesel blend. Increase and also decline are published with using biodiesel regarding particulate mass and number.…”

Air pollutants derived from diesel engines have more and more dangerous effect on the nature and on the built environment as well. One of the most important emission-component of a diesel engine running on conventional diesel is particulate matter. For measuring particulate matter there are many different widely used measurement methods. Using biofuel in diesel engines also causes emission of particulate matter. The basic aim of our work was to investigate and to evaluate the conventional biodiesel's and the new type TBK-Biodiesel's effect on the particulate relevant emission of a compression ignition engine. Particulate relevant emission mean in this case the four different measurement methods like filter smoke number, opacity, particulate mass and particulate number. With a rising blending rate of the-in internal combustion engine useable-bio derived fuels (standardized biodiesel and nonstandardized TBK-biodiesel) to fossil diesel the particulate relevant emission of the engine changes significantly. The tendencies in particulate relevant emission with growing blending rate are different among the measurement methods. Because of this situation biofuels cannot be evaluated clearly compared to fossil diesel in point of view of particulate relevant emission.

“…Also, studies on volatile organic compounds (VOCs), which are unregulated environmental pollutants emitted from engines using biodiesel, are also underway [21,22]. There is also active research on the morphology of soot from biodiesel and increasing interest in the fine dust generated [23,24].…”

This study describes the effects of palm oil biodiesel blended with diesel on the combustion performance, emission characteristics, and soot morphology in a 4-cylinder common-rail direct-injection (CRDI) diesel engine. The operational condition is idle speed, 750 rpm (the lowest speed of the test engine without any operation by driver), and the load conditions of the engine are 0 Nm and 40 Nm. Five kinds of biodiesel fuels are blended with diesel in 0%, 10%, 20%, 30%, and 100% proportions by volume. A pilot injection was applied at BTDC 15 °CA and 20 °CA. Part of the pilot injection affects the combustion of the main injection due to the deterioration of the spray because of the high viscosity of palm oil biodiesel. Palm oil biodiesel is sufficient to keep the engine stable in an idling state, but the fuel economy deteriorated. The deterioration of the spray due to the high viscosity of palm oil biodiesel is offset by the effect of oxygen content and high cetane number, resulting in a constant nitric oxide (NOx) emission. However, particulate matter (PM) is reduced. When the engine load is increased, the carbon monoxide (CO) emission amount increased because of the insufficient intake air and oxygen content to reduce the fuel-rich areas. However, when the palm oil biodiesel blend ratio was above a certain level, the influence of oxygen content in the palm oil biodiesel increased, resulting in reduced CO emission levels. Hydrocarbon (HC) was reduced by oxygen atoms in palm oil biodiesel. The sizes of particulates emitted from diesel engine using palm oil biodiesel decreased with an increased blend ratio because of oxidization of hydrocarbons absorbed on PM.
