The influence to mechanical properties of carbon fiber made by preoxidation retention time、temperature of low-oven and exhaust emission;

The characteristics of spark timing and A/F ratio effect on HC、CO and NO x emissions are analyzed through test data, these characteristics may be used to correctly select or control the spark timing and A/F ratio for decreasing the exhaust emission of a gasoline engine.

The static exhaust emission performance of automotive gasoline engines is influenced by a few factors such as engine s crankshaft rotate speed, load, air/fuel ration and spark timing, etc, the relationship between those factors and the engine exhaust emission performance is nonlinear.

Experimental Studies on Optimum Control of Exhaust Gas Emission for Gasoline Passeger Cars;

An introduction of the IMO convention concerning the emission of marine diesel is made.

Progress of hydrogen sulfide waste gas treatment;

,Ltd in these five years:including waste gas treatment,waste liquid treatment and treatment of waste water.

Through a project example,this article introduces the catalytic combustion which can be applied in the waste gas treatment of VOCs with small air volume and high concentrations,and illustrate its characteristics,advantages and notes.
