In this study an experimental investigation has been carried out on compression ignition engine to understand the engine behaviour like its performance and emission characteristics while using Aluminium oxide (Al2O3) nano particle as additive with a blend of diesel and biodiesel sourced from Jatropha and Pongamia vegetable oil. The Alumina nano particles are characterized by X- ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. The biodiesel is made engine ready with adoptable properties by carrying out standard alkali transesterification process. The alumina nano particles are blended with jatropha in the mass fractions of 50, 100, 150 ppm and with Pongamia biodiesel in the mass fractions of 40, 60 ppm using an ultrasonicator. The experiments are carried out in single cylinder four stroke variable compression ratio diesel engine by varying the load using eddy current dynamometer. The experimental results reveal that there is a significant improvement in the performance characteristics like brake thermal efficiency (BTHE) and brake specific fuel consumption (BSFC) and reduction in the emission constituents like carbon monoxide (CO) and unburned hydrocarbon (HC) but in turn increase in nitric oxide (NOx) emissions were observed.

A study on performance and emission of compression ignition (CI) engine has been made by utilizing biogas blends at different loads. The flow rate of biogas with air was important parameter to get the desired results. The blend of 30% with diesel was optimum which yielded optimum emission characteristics. Higher specific fuel consumption and lower brake thermal efficiency was observed when the proportion of biogas mixes with diesel in comparison with neat diesel. The out coming results from the experimental investigation exhibited reduction in NOx emission and smoke opacity. The other emissions hydrocarbon (HC) and carbon monoxide (CO) has been higher than diesel. The use of biogas as an alternative fuel in correct proportion with diesel can meet the energy demand on scarcity of conventional fuel.

In this present investigation titanium dioxide (TiO2) nano-fluid was blended with aphanizomenon flos (AF) biodiesel (20%)-diesel (80%) blend. Different percentages of TiO2 such as 5%, 10%, and 15%, was added with AF-D (aphanizomenon flos-diesel) blends. The blends are named as AFD-5TiO2, AFD-10TiO2, and AFD-15TiO2. The performance and emission parameters of a single cylinder CI engine fueled with AFD-TiO2 blends were experimentally investigated. The results reveal that, with the use of TiO2 nano particles, AFD-10TiO2 blend gave optimum results. BSFC decreased by about 5% and BTE increased by about 2% with the addition of TiO2 nano-particle as a catalyst. The tailpipe emissions such as CO, HC, smoke reduced drastically, but the NO emission increased, with the use of TiO2 nano-particles.

The present study examines the effect of silicon dioxide (SiO2) nano-additives on the performance and emission characteristics of a diesel engine fuelled with soybean biodiesel. Soybean biofuel was prepared using the transesterification process. The morphology of nano-additives was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). The Ultrasonication process was used for the homogeneous blending of nano-additives with biodiesel, while surfactant was used for the stabilisation of nano-additives. The physicochemical properties of pure and blended fuel samples were measured as per ASTM standards. The performance and emissions characteristics of different fuel samples were measured at different loading conditions. It was found that the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) increased by 3.48–6.39% and 5.81–9.88%, respectively, with the addition of SiO2 nano-additives. The carbon monoxide (CO), hydrocarbon (HC) and smoke emissions for nano-additive added blends were decreased by 1.9–17.5%, 20.56–27.5% and 10.16–23.54% compared to SBME25 fuel blends.

The objective of this work is to reduce viscosity and other related problems associated with biodiesel by adding non polluting additives. Magnetite is chosen as an additive in this work. Significant reason for using magnetite as an additive is that the magnetic nano particles (magnetite) can be collected from exhaust using magnetic billets in the tail pipe. Performance and emission test is carried out in single cylinder compression ignition engine using base and modified fuel and is compared to diesel. Modified fuel consists of 98.5% base fuel (Rice bran oil methyl ester), 1.3% additives (magnetite) and 0.2% surfactant (tri methyl ammonium hydroxide) by volume. The experimental work confirmed that by adding magnetite to methyl esters of rice bran oil enhances the brake thermal efficiency by 4.27% with 5.17% reduction in SFC. In addition, 10.8%, 9.1% and 8.49% reduction in HC, CO and nox emissions is observed respectively.

In this contemporary era it is mandatory to increasing the usage of non edible biodiesel to replace the fossil fuels. This non edible biodiesels are produced from vegetable oils which is clean burning and renewable. This paper deals with the performance and emission characteristics on diesel engine with blends of Castor oil as biodiesel. Castor oil biodiesel is prepared by the use of adding 1% v/v H2SO4 after the transesterification process. The engine tests were performed with various blends B20, B40, B60 on a single cylinder, 4-stroke, diesel engine. The result shows Higher performance and lower emissions for B20 than the diesel and other blends. The brake thermal efficiency is higher than the diesel and CO, HC and NOX emissions were 22%, 8.4%, and 21% lesser than that of diesel.

Day to day increasing vehicles usage for human activities is caused to accumulate greenhouse emissions into the environment. The biodiesel is a best alternative fuel to run diesel engines. But its lower Calorific value and higher NOx emissions makes the consumer should compromise with engine performance and emission characteristics. As we know, that the use of additives to improve engine Combustion and emissions are caused to increase the fuel cost due to the higher cost of additives. The biodiesel conversion process of third generation biodiesel is costlier and required technological advancements for qualitative fuel. In the present work, the author used mixed culture micro algal particles in Coconut biodiesel (CCNME+AP) to improve engine characteristics. The Brake Thermal Efficiency (BTE) was enhanced, and the NOx emissions were less due to the absorption of heat in the Combustion chamber, it led to cool combustion phenomena with the Algal particles contained Coconut Biodiesel (CCNME+AP).

Cooking Oil

The main reason for the limited usage of biodiesel is it tends to oxidize when exposed to air. It is anticipated that the addition of an antioxidant along with graphene nano particle improves combustion of diesel-biodiesel blend. In the present research biodiesel made from the transesterification of waste cooking oil is used. Three synthetic antioxidants butylated hydroxytoluene (BHT), 2(3)-t-butyl-4-hydroxyanisole (BHA) and tert butylhydroquinone (TBHQ) along with 30 ppm of graphene nano particle were added at a volume fraction of 1000 ppm to diesel–biodiesel blends (B20). The performance and emission tests were performed at constant engine speed of 1500 rpm. Because of the inclusion of graphene nano particles, surface area to the volume ratio of the fuel is augmented enhancing the mixing ability and chemical responsiveness of the fuel during burning causing superior performance, combustion and emission aspects of compression ignition engine. The results revealed that there was a slight increase in brake power and brake thermal efficiency of about 0.29%, 0.585%, 0.58% and 6.22%, 3.11%, 3.31% for B20GrBHT10000, B20GrBHA1000 and B20GrTBHQ1000, respectively, compared to B20. Additionally, BSFC, HC and NOx emissions were reduced to considerable levels for the reformed fuel.
