Low accuracy is the main challenge that plagues application of engine modeling technology at present. In this paper, correlation analysis used to analyze influencing factors torque and NOx (nitrogen oxides) raw emission performance from a statistical point view, on basis, regression algorithm construct prediction model. The RMSE between value true reaches 4.6186, R2 1.00. Prediction 67.599, 0.9...

nitrogen oxides (nox) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. in-cylinder high temperature flame and high oxygen concentration are the parameters which affect the nox emissions. the egr system is a very effective way for reducing nox emission from a diesel engine (via reduction of these parameters), particularly at the hi...

A global concern that has arisen in the present time due to the constant depletion of the fossil fuels reservoirs and also due to the greenhouse gases emitted by use these fuels has led many researchers to find alternate sources of energy, out of which biodiesels have found a suitable place. Thus, in this effort of finding the compatibility of bio-fuels in present diesel engines, many experimen...

Diesel engines, generating harmful NOx, will be subjected to legislation that stipulates large reductions in emission levels beginning in 2007. For controlling emissions, a NOx sensor is needed to provide feedback to the engine management system. In this work, we take advantage of the high mass sensitivity of resonant sensors and the chemical reaction of barium carbonate (BaCO3) with NO2 gas as...
