In normal theoretical A-F ratio conditions,double peaks appear on light intensity curve of CH(431.5nm),C 2(516.5nm) and H 2O *(588nm) radica ls and light emission within the fire delay period is light emission of radicals .
Understand the polymer catch fire with combustion characteristic, can design for a fire safe engineering, a fire endangers valuation to provide the method and technique, at physically applied aspect exertive important function.
If they don't through the processing, not only will they pollute the soil and the headwaters, sometimes even will cause the dirty oil to catch fire, threating the people's life safety, result in the economy lose of our country, but also will endanger the benefits of the oil-field themselves.
The result revealed that the main reason why cold starting in diesel engine of vehicle was difficult was decrease of starting moment, increase of resistance moment and difficulty of catching fire of fuel when environment temperature was low.
Some research is done on prevention of electrostatic fire at the filling station in the logistics zone, such as causes, conditions catching fire, general regularity, danger and prevention of human static electricity, and countermeasures against electrostatic fire.
The results illustrate that the combustion happens in advance and the ignition delay period is shortened.
Ignition delay time was found to be longer than deflagration-to-detonation transition (DDT) time, and the sum of the two would change little as cycle frequency increased.
The results show that F-T diesel fuel exhibits a slightly longer injection delay and injection duration, an average of 18.7% shorter ignition delay, and a comparable total combustion duration when compared to those of conventional diesel fuel.
Control of homogeneous charge compression ignition combustion in a two-cylinder gasoline direct injection engine with negative v
Homogeneous charge compression ignition (HCCI) has challenges in ignition timing control, combustion rate control, and operating range extension.
