modeling the effects of biodiesel-diesel fuel blends on co2 emission of a diesel engine by response surface methodology

چکیده

nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. inthis research, the application of response surface methodology (rsm) was highlighted to investigate the effects of biodiesel-diesel blends (b0, b20, b50 and b100), engine operating parameters (engine load and  speed) on co2 emission of a diesel engine. the experiments were conducted on a four cylinder direct-injection diesel engine based on three-factor five-level central composite rotatable design. the developed mathematical models were helpful to predict the response parameters and further to identify the significant interactions between the input factors and the responses. the use of biodiesel resulted in higher emission of co2. the results also showed that an increase in engine speed  leads to an increase in the emission of co2.on the other hand,co2 emission is higher at low engine loads,while is lower at high engine loads.

Emission Performance of a Diesel Engine Running on Biodiesel Fuel at Different Compression Ratios

In the present study emission performance of a diesel engine (Lister Petter) was evaluated at different compression ratios and engine loads with soybean methyl ester and its 25%, 50%, 75% blends with diesel fuel at constant speed 1500 rpm. Exhaust emissions included CO, CO2, HC and NOx. The compression ratio and engine load varied from 14 to 20 with an interval 1 and 25 to...

The effect of a novel hybrid nano-catalyst in diesel-biodiesel fuel blends on the energy balance of a diesel engine

In internal combustion engines, only about a third of the total fuel input energy is converted into useful work. If the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. The main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing ce...
