As the characteristics of fume emission,the author proposed that the environmental protection departments and relevant u-nits should intensify law enforcement and strengthen the spot checks on the catering industry as well as the super-vision and management work to ensure the standards of soot emissions.

Installation of continuous flue gas emission monitoring system of thermal power plants in China and some problems in its application;

Whether flue gas emission during coal-to-electricity conversion is sustainable determines not only power industry\'s growth,but also coal industry\'s growth.

New measuring method of smoke emission for diesel vehicle;

A engine bench test is carried out by means of exhaust gas recirculation, and a certain proportion of exhaust gas is mixed with inlet air to monitor the effect of the environment in the highway tunnel on smoke emission.

It is confirmed by the experiments that soot emission can be reduced by using diesel methanol compound combustion(DMCC).

The effect of CO2 concentration in the co-flow on the auto-ignition characteristics and soot emission of central jets flames were investigated.

Taking advantage of this model, the influence of injection rules, turbocharging pressure and compression ratio on soot emission can be predicted, which can be helpful to predict and improve the soot emis.

An additional electric supercharger(ES) system was developed to reduce the black smoke emission from diesel engine of bus.
