Determination of physico chemical properties of biodiesel from Citrullus lanatus seeds oil and diesel blends

In this research, the performance and emissions of a four-stroke spark ignition engine fuelled with varying proportion of propanol-camphor and gasoline blends were investigated. The physicochemical properties such as specific gravity, viscosity, fire point, flash point, and iodine value (I.V.) of the blends were determined, and the values obtained conform to the ASTM standard. Sample P0B (100% of pure gasoline and 5 g of camphor) had the best physicochemical property values higher than those of the least sample of P15B by the following percentages: specific gravity (0.5%), viscosity (30.8%), fire point (5.08%), flash point (21.8%), and I.V. sample (0.5%). Also, the engine performance parameters such as brake power, brake thermal efficiency, brake mean effective pressure (BMEP), and specific fuel consumption were generated from the engine-measured parameters. Sample P0B has the best specific fuel consumption for the torque of 3 N m with a value of 22.77 kg/kW h, and sample P0A (100% of pure gasoline) has the best fuel consumption for a torque of 6 N m with a value of 12.52 kg/kW h. For brake thermal efficiency, sample P0B gives the best brake thermal efficiency at the two constant torques with a value of 0.36 for torque 3 N m and 0.67 for torque 6 N m. Sample P15C (85% of gasoline, 15% of propanol, and 5 g of camphor) gives the best BMEP at torque 3 N m with a value of 1.92 bar, and sample P5C (95% of gasoline, 5% of propanol, and 10 g of camphor) gives the best BMEP at 6 N m with a value of 3.85 bar. Exhaust emissions were analyzed for unburned hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO 2 ), and nitrogen oxide (NOx). The results showed that increasing the blending percentage reduces the emitted concentration of CO, HC, and NOx. Carbon monoxide emission was found to be lowest at sample P10A (90% of gasoline and 10% of propanol) for torque 3 N m with a value of 0.16, and at torque 6 N m, the sample with the lowest percentage was P15C with a percentage of 0.21.

“…The engine performance and emissions of any engine intern depends upon the quality of the fuel being used in the engine [84][85][86]. Biodiesel as a fuel for a diesel engine has major problems, such as higher viscosity, low heating value and low volatility [87][88][89][90][91][92][93]. The pre-heating of biodiesel or crude oils decreases their viscosity and makes them suitable for diesel engines [94,95].…”

The ever-increasing demand for transport is sustained by internal combustion (IC) engines. The demand for transport energy is large and continuously increasing across the globe. Though there are few alternative options emerging that may eliminate the IC engine, they are in a developing stage, meaning the burden of transportation has to be borne by IC engines until at least the near future. Hence, IC engines continue to be the prime mechanism to sustain transportation in general. However, the scarcity of fossil fuels and its rising prices have forced nations to look for alternate fuels. Biodiesel has been emerged as the replacement of diesel as fuel for diesel engines. The use of biodiesel in the existing diesel engine is not that efficient when it is compared with diesel run engine. Therefore, the biodiesel engine must be suitably improved in its design and developments pertaining to the intake manifold, fuel injection system, combustion chamber and exhaust manifold to get the maximum power output, improved brake thermal efficiency with reduced fuel consumption and exhaust emissions that are compatible with international standards. This paper reviews the efforts put by different researchers in modifying the engine components and systems to develop a diesel engine run on biodiesel for better performance, progressive combustion and improved emissions.

[9][10][11] The benefits of nonedible oils as biodiesel are the high aromatic content and minimum sulfur emissions, comparable diesel fuel properties, high lubricity, oxygen content, and cetane number, while the few limitations are high viscosity, flash and pour point, low calorific value, and volatility. 12,13 Diethyl ether (DEE) is suitable as a liquid fuel additive in the diesel and biodiesel fuel for its high miscibility, increasing the cetane number, and calorific value of the base fuel, providing extra oxygen atoms, high flammability, and acceptable density for on-board storage.…”

An investigational analysis was performed to assess the effect of diethyl ether (DEE) that acts as an oxygenated additive in Jatropha biodiesel and diesel fuel blends on the performance enhancement and emission reduction of a variable compression ratio (CR) diesel engine. The DEE (10% vol) is added to different concentration levels of Jatropha biodiesel (B5, B10, and B20). The Jatropha biodiesel (JME) is prepared by the transesterification reaction and DEE is prepared through acid distillation
