Emission and combustion parameters of common rail direct injection combustion engine with differe... more Emission and combustion parameters of common rail direct injection combustion engine with different proportions of exhaust gas recirculation (EGR) rate and long-carbon-chain alcohol blends on performance are the main motive of this research. To lessen the dependency on diesel fuel and reduce harmful emissions, 1-hexanol is used, as it has better fuel properties than small-carbon-chain alcohol, and it can be blended with diesel. In common rail direct injection combustion engine, research was conducted, in which fuel blends (1-hexanol-diesel) were variant, i.e., (10%, 20%, 30%) by volume whereas engine speed was fixed at 1500 rpm by varying the load at 25% step from 25 to 100%. Blends were examined with various exhaust gas recirculation rates (10 and 20%) to see what impact they have on engine properties. It was observed that the higher the proportion of 1-Hexanol, the lower the engine performance. The research revealed that for the blend D70H30, around 8.24% rise in brake specific fu...

KME produced by base catalyzed transesterification of non-edible karanja oil was blended with DTBP in different volume proportions to result KMED1 (99% KME + 1% DTBP), KMED2 (98% KME + 2% DTBP), KMED3 (97% KME + 3% DTBP) and KMED5 (95% KME + 5% DTBP) fuel blends. With increase in DTBP content, viscosity was reduced, whereas the cold flow properties, cetane index and calorific value were enhanced. Engine test results exhibited improvement in brake thermal efficiency and brake specific energy consumption for all blends compared to neat KME. Combustion analysis showed improved combustion with rise in DTBP content in the blends. The CO, HC and NOx emissions with KME-DTBP blends were less compared to neat KME and the same significantly reduced with rise in DTBP percentage in...

The experiment was conducted in an IDI CI engine at 34, 67, and 100% load conditions at constant 1500 rpm. Totally, three blends were used for the experiment. The first blend was 100% diesel (PD), the second blend was Thumba biodiesel 10% diesel 90% (Blend 1), and the third blend was Thumba biodiesel 20% and diesel 80% (Blend 2). The experimental result of both biodiesel blends was compared with diesel. From the experimental result, it was found that both the biodiesel blends showed comparable results of BThE, But UHC was lower for the blends whereas NOx was higher for both the blends compared to diesel. From the experimental work, it was also found that the Blend 1 (Biodiesel containing Thumba biodiesel 10% and Diesel 90%) had better results than Blend 2. Also, Blend 1 showed comparable results to diesel.

Experiments are performed on a diesel engine working in single fuel mode using fossil diesel (FD)... more Experiments are performed on a diesel engine working in single fuel mode using fossil diesel (FD) as well as 5% and 10% (v/v) di-ethyl ether (DEE) additives with FD as fuels as well as in dual fuel mode using the above fuels as pilot fuels along with producer gas (PG) as primary fuel. This study aims to draw comparative analyses of engine combustion, performance and emission characteristics using the above fuel combinations to establish the most suitable fuel strategy for a diesel engine. The study revealed greater control over nitric oxide (NO) and smoke opacity in dual fuel mode compared to single fuel mode operations. Addition of DEE with FD, produced lower HC and CO emissions, comparable NO emissions along with reduced smoke opacity compared to FD in both modes of operation. Further, in dual fuel mode operation, the diesel percentage energy substitution (PES) reduced with increase in DEE content in the blends. The tradeoff study involving engine performance and emissions with re...

This study investigates the emission and combustion characteristics of diesel engines operating under the reactivity-controlled compression ignition mode. The primary objective of this research is to examine the effect of fuel injection timings (7.5, 12.5 and 17.5 bTDC) and injection pressure (500 and 1000 bar), experimental testing is carried out on single cylinder water-cooled testing engines at constant speed of 1500 rpm with variable engine load (16, 20 and 24 Nm). In case of a fuel injection pressure of 1000 bar, the maximum brake specific fuel consumption of 0.42 kg/kWh is registered with a brake mean effective pressure of 3.2 bar. In this experimental study, Box-Behnken based response surface methodology was used to predict the optimal input parameters, resulting in the optimal combination of output and emission parameters. In addition, a statistically relevant test analysis of variance has been developed to obtain a 'regression model.' Results have shown that the proposed 'Regression Model' is ideally suited to 0.095 standard deviation, 0.972 modified R2 and 18.482 acceptable accuracy. This analysis also attempts to describe the application of the response surface methodology analysis to optimize the emission and performance parameters.

The primary objective of this research is to design an alternative fuel having additive 2-Ethylhexyl nitrate of high cetane number and additive triacetin of low cetane number blended with palm kernel to analyse exhaust emission characteristics and engine performance. For the purpose, biodiesel made from palm kernel was added to pure diesel along with 20% (by volume) of two different additives (2-Ethylhexyl nitrate, triacetin). As compared with pure diesel, some of our fuel blends show better performance and have low emission which is much needed in the present scenario.

Fish methyl ester is available abundantly. The present experiment assess the performance and emission distinctive of a diesel engine using dissimilar blends of methyl ester of fish, 2-EHN and ethanol with mineral diesel. Methyl ester and diesel additive was blended with diesel in proportions of 20% and 100% by mass and studied under full load conditions. The performance and emission parameters were found to be better than the mineral diesel.

Leucas zeylanica plant is noncomestible in nature and available abundantly. Leucas zeylanica methyl ester is renewable and least polluting fuel, which can supplement fossil fuels with unmodified engine condition. The existing experimentation assesses the performance and emission analysis by using various blends of leucas zeylanica methyl ester, diesel, and diesel additives like 2-ethylhexyl nitrate. This experimental investigation gives less engine emission and better performance as compared with mineral diesel. In the radical portion of this investigation, fuzzy-based Taguchi optimization for predicting the optimum input blends results in the optimum combination of performance and emissions parameter.
