“…On the other hand, Haik et al 30 found that algae oil methyl ester was responsible for higher cylinder pressure rise rates dp/du (a typical 'surrogate' property of combustion noise) compared with neat diesel fuel or raw algae oil for their indirectinjection diesel engine. Bunce et al 31 proposed that a re-adjustment of the engine calibration is required in order to attain decreased pollutant and noise emissions simultaneously with the addition of soy biodiesel in the fuel blend. Although Anand et al 32 did not specifically measure combustion noise, they too reported on the cylinder pressure rise rate for neat karanja biodiesel fuel blends and concluded that the trend versus neat diesel fuel was not clear; in fact, the contributing factors acted in favour or against each fuel blend depending on the speed or load conditions.…”

In the current study, experimental tests were conducted on a turbocharged truck diesel engine in order to investigate the mechanism of combustion noise radiation during various accelerations and for various fuel blends. With this aim, a fully instrumented test bed was set up in order to capture the development of key engine and turbocharger parameters. Apart from the baseline diesel fuel, the engine was operated with a blend of diesel with either 30 vol % biodiesel or 25 vol % n-butanol. Analytical diagrams are provided to explain the behaviour of combustion noise radiation in conjunction with the cylinder pressure, the pressure rise rates, the frequency spectrum and the turbocharger and governor-fuel pump responses. The blend of diesel fuel with n-butanol exhibited the highest noise emissions throughout each of the transient tests examined, with differences up to 4 dBA from those with neat diesel operation. On the other hand, the biodiesel blend was found to behave marginally noisier than neat diesel oil but without a clear trend established throughout the transient events.

“…Volli and Singh 3 suggested mahua biodiesel production from by pyrolysis technique. Similarly biodiesel obtained from edible oils such as sunflower, palm, soybean, cottonseed, ricebran, etc., have been studied and tested by many researchers, Shlick et al, Bunce et al, Dayong and Yun, Peterson et al, and Nabi et al [4][5][6][7][8] It has been found that edible oil based biodiesels have a good scope for use in CI engines. Few attempts have also been made for the production of non-edible oil based biodiesels such as Jatropha, karanja, polanga, mahua, etc., and their performance has been checked in CI engines, Yadav The use of biodiesels in CI engines does not affect the performance parameters and it has an advantage of reduced harmful emissions such as CO, No x , unburnt hydrocarbons (HC), smoke opacity.…”

“…Research is now being focused to find the optimum combination of input variables in terms of performance and emission characteristics. Few Authors have reported the optimum values of responses in diesel engines, Bunce et al, 5 Ganapathy et al, 12 Jindal and Salvi, Maheshwari et al, Balajiganesh and Reddy, and Karuppasamy et al [14][15][16][17] There are various tools available for optimization of engine performance and emission parameters such as Response surface methodology (RSM) based on Central composite rotatable design (CCRD), Artificial neural network (ANN), Genetic algorithm (GA), fuzzy logic, etc. But till date no work has been reported for predicting optimum performance and emission parameters at particular input variables of mahua biodiesel.…”

The important fuel properties of mahua biodiesel blends were compared with those of high speed diesel and biodiesel standards. Variation of brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), P max , CO, NO x , hydrocarbons, and smoke opacity across compression ratio, blending ratio and load were studied successfully using response surface methodology based on Central composite rotatable design. The trends similar to general theory of compression ignition engines (CI) were obtained. Optimum performance and emission parameters were determined by considering the significant variables affecting the diesel engine. Significant reduction in emissions at 23% blending ratio were observed as compared to neat diesel at optimum input variables. Hence mahua biodiesel is an environment friendly alternate fuel over diesel and has good scope to run the compression ignition engines. V C 2013 AIP Publishing LLC. [http://dx.

Abstract. Biodiesel is a mixture of esters of short chain alcohols, produced as an alternative fuel for mineral diesel substitution. It is originated from renewable sources (fats and oils) and is less pollutants. But for its implementation, it is necessary to analyze some important quality parameters. A very important fuel`s feature is the calorific value, which represents the amount of heat transferred into the chamber during the combustion and indicates the available energy in fuel. The calorific value is obtained experimentally using a calorimetric bomb. The higher the calorific value, the higher is the yield of the fuel. The aim of this study is to determine the calorific value of rapeseed, soybean, jatropha curcas and crambe biodiesel using a calorimetric bomb. The results were associated with the ethyl ester composition of each biodiesel. The crambe biodiesel shows the highest calorific value (∆H= 40564 J g -1 ) influenced by the high amount of long chain ethyl ester originated from behenic acid (C22:0) that composes 57.2% of crambe oil. The rapeseed, soybean and jatropha curcas biodiesel that exhibit approximately the same amount of long chain ethyl ester showed calorific values near to ∆H= 39450 J g -1 .
