1. A comparative analysis is carried out between common light-off temperature meth-od and uncommon light-off ties method for evaluating the light-off performance.

2. The light-off performance of automotive catalytic converters is very important for the stringent vehicle emission regulation.

3. A mathematical model was established to simulate the light-off performance of a catalytic converter. Simulation results and the experimental values are agreed well.

4. Life ,[/light-off.html] thin and light-off time and time again frivolous tireless.

5. The light-off time and emission temperature characteristics of FD catalyst are analyzed.

6. Results show that it has low light-off temperature while we noticed a delaying phenomenon existing between catalytic purification activity and temperature increase.

7. We see classroom light-off all the time in the evening, the aunt drives a talent to go.

8. The heat and mass transfer model of chemical reactions in monolith was coupled to simulate the light-off characteristics of catalytic converter during cold start by CFD.

9. According to the experience of major companies in Europe and USA, general single light-off technology and HC trapping catalytic technology can be suitable solutions.

10. And, finally, the value of conduction coefficient and wall thickness of the monolith almost have no obvious effect on the light-off temperature.

11. The effects of converter position, ignition timing and idle speed on catalytic converter light-off behavior were studied on an electronically controlled LPG injection engine.

12. The exhaust gas temperatures rise and variation during EUIII test cycle and its impact on the light-off time, ceramic temperature, dynamic response behavior and emission results were studied.

13. The result shows the change of its temperature field and concentration field in light-off course.

14. You should be able to identify the major parts of a boiler and its functions. Also, you will learn about safety precautions that must be observed during boiler light-off .

15. It may effectively reduce the HC emissions to use a catalyst with low light-off temperature, close-coupled catalyst, HC traps, second air injection and electrically heated catalyst.

16. Between the two aspheric IOLs, there was no difference both in light-off and light-on.

17. Flow velocity distributing in monolith gives great effect on transform efficiency and light-off character and life of catalytic converter.

18. Experimental results show that secondary air injection can shorten the light-off time of three-way catalytic converter, and effectively reduce the emissions of HC and CO during cold start.

19. Experimental results show that the position of the converter nearer to the exhaust port, the retard ignition timing and the higher idle speed can promote the catalytic converter light-off.
