查询词典 octane value

The heavy oil combustion activator mainly used in heating stove of steel rolled, industrial stove, power plant stove, glass furnace ,metal furnace ,ceramic roller kiln and channel kiln .It can accelerate combustion , prevent over-burning, reduce the harmful gas emission. Its energy-saving reaches to 5-8%. Diesel oil combustion activator mainly used in the diesel oil engine which can strengthen atomization ,improve ignition conditions, adjust the value of cetane,restrict intense or knocking vibrations, reduce the fuel de-compound and black smoke emission, prevent over-burning, carbonization and reduce the machine's friction. Its fuel-saving reaches to 3-5%. High efficiency gasoline combustion activator mainly used in gasoline engine, which can improve the gasoline octane rating ,restrain extensive or knocking vibrations, reduce fuel de-compound , prevent over burning , carbonization, reducing machine's friction and toxic gas or black smoke emission, Its fuel saving reaches to 3-5%.

该产品分为重油、柴油和汽油燃烧催化剂三大类，重油燃烧催化剂主要用于轧钢加热炉，工业锅炉，发电厂锅炉，玻璃熔窑，金属熔炼炉，陶瓷辊道窑，隧道窑中，能够促进燃烧，防止结焦，节能达5-8%，减少有害气体的排放；柴油燃烧催化剂主要用于柴油发动机中，起到增强雾化、改善着火条件，调整十六烷值，抑制隆震爆震，降低燃料分解，防止结焦积碳的作用，同时减少机器磨损，节约燃料3-5%，减少黑烟及有害气体的排放；高效汽油燃烧催化剂用于汽油发动机中，能提高汽油辛烷值，平抑隆震爆震，降低燃料分解，防止结焦积碳，减少机器磨损，节约燃料3-5%，减少有害气体及黑烟的排放。

The experimental results indicated that under the steady operating conditions, the ignition timing of the base fuel (PRF90-90% iso-octane+10% n- heptane), which is equivalent to RON 90, delayed and the peak value of the heat release rate was low compared to the base fuel with single additive (Ditert-butyl peroxide-DTBP, Dicumyl peroxide-DCP, Tert-butyl hydroperoxide-TBHP, Tert-butyl cumyl peroxide -TBCP or Cumene hydroperoxide-CPO) which advanced ignition timing and increased the peak of the heat release rate obviously.

试验结果分析表明，在HCCI发动机燃烧稳定工况下，没有添加剂的基础燃料记作PRF90(为90%异辛烷与10%正庚烷的混合，相当于90号汽油)着火滞后，燃烧放热率峰值低，而混有单一添加剂(Ditert-butyl peroxide-DTBP、Dicumyl peroxide-DCP、Tert-butyl hydroperoxide-TBHP、Tert-butyl cumyl peroxide-TBCP或Cumene hydroperoxide-CPO)的基础燃料则着火明显提前，燃烧放热峰值升高。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
