Influence of multiple pre-injection on engine performance based on exhaust gas control [PDF]
With the development of the society, the emission laws are increasingly strict, and EGR and multiple pre-injection strategy can effectively reduce emissions. In order to study the influence of EGR rate and pre-injection on the emission and performance of

High Resolution Modelling of Traffic Emissions Using the Large Eddy Simulation Code Fluidity
The large eddy simulation (LES) code Fluidity was used to simulate the dispersion of NOx traffic emissions along a road in London. The traffic emissions were represented by moving volume sources, one for each vehicle, with time-varying emission rates ...

Co-firing of coal and woody biomass under conditions of reburning technology with natural gas
It is a continuous imperative to establish the most efficient process of conversion of primary energy from fuel through combustion, which also has the least possible harmful effect on the environment. In this time of expressed demands for decarbonisation,
