Review on Research and Development of Diesel Engine Energy Saving and Emission Reduction Technology
Diesel engine as an important thermal power machinery,is widely used in transportation,shipping,engineering construction,agricultural production and national defense construction and many other fields,greatly changed people's way of production and life.With the development of industry,diesel engine has been widely used,but also exposed a lot of problems,among which the excessive consumption of fuel and exhaust emissions and other harm to the environment gradually attracted people's attention.Now reducing the energy consumption and pollutant emission of diesel engine has become the main problem facing the development of diesel engine.In this paper,the energy-saving and emission reduction technology of diesel engine is studied in detail.Firstly,the types,hazards and causes of diesel engine pollutants are introduced.Then the main ways of energy saving and emission reduction of diesel engines are studied in detail.This paper discusses in detail from the improvement of fuel quality of pre-processing,electronic fuel injection technology of in-engine purification,and nitrogen oxide storage and reduction technology(NSR)of post-processing.Finally,the development trend of diesel engine energy saving and emission reduction technology is forecasted.Through this study,it can provide some reference for the development of diesel engine.
