The primary aim of this study is to alternate between conventional fossil fuels and reduce the emissions greenhouse gases sulphur dioxide from diesel engine. In current study, in order mitigate NOx emissions, EGR technique was implemented utilizing hybrid biodiesel at three varying proportions 5%, 10% 15% an optimum compression ratio 20:1. findings demonstrate that for a alternative 20:1 fully ...

This paper reports the results of an experimental investigation on the effect of the EGR on the pollutants emission, especially on oxides of nitrogen, from the exhaust gases and performance of the spark ignition engine. Also along with experimental work, a mathematical model for the determination of the effect of EGR on the peak cycle temperature and for the prediction of its effect on the NOx ...

Exhaust Gas Recirculation (EGR) concept is the most simple and Abstract more economical method for NO pollutant reduction in spark ignition engines. However, when the higher amount of the EGR gas enters into the engine, the power, torque and fuel economy of the engine decrease. One effective solution for reduction of undesirable effect of this method is to use cooled EGR, that results in more r...
