“…One of the most advantageous branches in the biofuel sector is seen to be the production of straight vegetable oil (SVO) for direct use as fuel in diesel engines. There has been renewed interest in this activity in recent years, for stationary applications in the fields of agriculture, power generation and industry [10][11][12][13][14][15]. These sectors are major consumers of fuel oils, either high distillates (diesel), medium distillates (DDO Distillate Diesel Oil) or heavy Fuel Oil 180 (FO180), which might be wholly or partially replaced with SVO [10,12,13].…”

“…The NO x emissions substantially increase with temperatures. In many experiments, there has been decrease in nitrogen oxides emissions with biodiesel perhaps because in-cylinder temperature is lower which can be due to lower calorific value of the fuel [7].In single cylinder engine running with palm [8,9] and jatropha biodiesel [10,11], the reported results indicate lower brake powers and higher brake specific fuel consumptions (BSFC) [12].…”

Abstract-As we know from year to year the emission standards are become stringent due to Global Warming Effect. It is difficult for the developing countries like India to meet such stringent emission standards as it involves expensive technologies. In this crisis, there is a need to search for the costeffective methods to reduce emissions from IC engines. Previous research shows that Biodiesel fueled diesel engines emit less CO 2, HC and Smoke emissions than Diesel fueled Engines. In this study, a dual biodiesel blend, mixture of two different kinds of biodiesel namely palm and jatropha with diesel was considered for evaluation in a single cylinder DI diesel engine after going through physical properties analysis. The objective of present work is to investigate experimentally the effects of Dual Bio-diesel blends on performance and emissions of VCR DI constant speed Diesel Engine under various loads and Compression Ratios. Performance and Emission Tests were conducted on VCR Diesel Engine running at a constant speed of 1500 r.p.m. under various loads and compression ratios. Results showed that Brake power (BP) is increased by 1.5% for the test fuel D90PB5JB5 compared to Diesel. BSFC of D90JB5PB5 Test Fuel is almost same as that of conventional Diesel fuel whereas D80JB10PB10 test fuel showed a slight increase in BSFC at all loads when compared to fossil Diesel fuel. Brake Thermal Efficiency is maximum for D90JB5PB5 Bio-diesel blend and it is minimum for D80JB10PB10 when compared to diesel. It was observed that CO and HC emissions were decreased when Engine is running with dualbiodiesel blends when compared to conventional diesel fuel.

“…Table 1. Properties of vegetable oil compared to petro-diesel (Altın et al, 2001;Pugazhvadivu & Jeyachandran, 2005;Senthil Kumar et al, 2005;Agarwal & Agarwal, 2007;Murugesan et al, 2009;Misra & Murthy, 2011;Chauhan et al, 2012;Bousbaa et al, 2012;Yahya & Norhisyam, 2012 As shown in Table 1, the kinematic viscosity, cetane number, higher heating value, density and flash point of the alternative fuel for the CI engine are all substandard to petro-diesel. Based on this concern, this research has grouped the alternative fuels for the CI engine ranging from vegetable oil to higher viscous fuels (HVFs).…”

This paper investigates the in-cylinder air flow of a compression ignition (CI) engine modified by a guide vane swirl and tumble device (GVSTD) where the number of GVSTD vanes was varied to optimize its dimension to improve the CI engine performance using higher viscous fuel (HVF). Hence, eleven 3D CI engine models were developed; a base model and 10 GVSTD models, via SolidWorks. Computational fluid dynamics (CFD) were performed by utilizing ANSYS-CFX and simulated under motored conditions for two continuous complete cycles. The results are presented of the simulation of in-cylinder pressure, turbulence kinetic energy (TKE) and velocity during the fuel injection period until expansion. The recorded increments from six vanes of GVSTD were about 1.3%, 0.2% and 22% of the above results. Hence, this paper concludes that GVSTD has the potential to improve CI engine performance using HVF.
