“…NO can also be formed through different mechanisms, but the model used here has taken care of NO formation through only thermal or Zeldovich mechanism. Similar NO formation model has been used by Kuleshov [21] for simulation of direct injection diesel engine. The model first calculates step by step equilibrium composition of combustion products for eighteen species in the burnt gas zone followed by the kinetic calculation of thermal NO following Zeldovich mechanism.…”

The effect of addition of jatropha biodiesel to mineral diesel on the performance and emission characteristics of a conventional compression ignition engine have been experimentally investigated and compared with simulated data using Diesel-RK software. The experiments were carried out using pure diesel (B0) and pure jatropha biodiesel (JB100) as fuels. The performance characteristics shows that brake specific fuel consumption (BSFC) increases and brake thermal efficiency decreases with the use of jatropha biodiesel. Experimentally, pure diesel has maximum efficiency 29.6%, where as pure biodiesel has maximum efficiency of 21.2%. In the simulation, the pure diesel has maximum efficiency 30.3% where as pure jatropha biodiesel has the maximum efficiency of 27.5%. In respect of emission characteristics, NO x emission is found to increase with load as well as use of biodiesel in both experimental and simulation study. After the successful validation of the numerical study with the experimental, another simulation was done, where the performance, combustion and emission characteristics of the same engine fueled with pure diesel (B0), pure jatropha biodiesel (JB100) and 50% jatropha blend (JB50) were derived. In the numerical study it is found that, with the use of jatropha biodiesel the BSFC increases whereas brake thermal efficiency decreases. Combustion characteristics show an increase in peak cylinder pressure and a decrease in ignition delay period with the increase in biodiesel share in the blends; whereas the emission of NO x and CO 2 increases; smoke and PM emission decreases for the same.

“…Therefore, only NO formation following Zeldovich mechanism is considered in this study. Kuleshov 2006 described the procedure and that has been adapted in this model. It consists of step by step calculation of equilibrium composition of combustion products for eighteen species in the burnt gas zone.…”

A numerical simulation has been carried out in this study to evaluate the effect of alcohol addition to the blends of diesel and palm stearin biodiesel on the performance, combustion and emission of a diesel engine. The commercial software Diesel-RK has been used in this study to simulate a single-cylinder, naturally aspirated, direct injection, four-stroke diesel engine. The simulated results have been validated against experimental observation for the base fuel diesel. The effects of two alcohols, namely ethanol and methanol have been separately investigated and compared. The results indicate that although the brakespecific fuel consumption is slightly increased, the other performance characteristics and the entire combustion and emission parameters are improved with alcohol addition to diesel-biodiesel blends. The instantaneous heat release rate, ignition delay and oxides of nitrogen emission are found to be more with methanol than with ethanol. The diesel-biodiesel blend also shows better combustion and emission characteristics than that of diesel except oxides of nitrogen emission.
