light-off

基本解釋

The light-off performance of automotive catalytic converters is very important for the stringent vehicle emission regulation.
車用催化轉(zhuǎn)化器的起燃特性對(duì)滿足日益嚴(yán)格的排放法規(guī)是至關(guān)重要的。
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.
研究了電控LPG發(fā)動(dòng)機(jī)的催化轉(zhuǎn)化器安裝位置、點(diǎn)火提前角和怠速轉(zhuǎn)速對(duì)催化轉(zhuǎn)化器快速起燃的影響。
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.
試驗(yàn)結(jié)果表明，催化轉(zhuǎn)化器的位置距排氣口近可提高排氣溫度，大大提高催化轉(zhuǎn)化器的轉(zhuǎn)化效率；推遲點(diǎn)火提前角和提高怠速轉(zhuǎn)速均有利于使催化轉(zhuǎn)化器進(jìn)入快速起燃狀態(tài)。

They used light-sensitive molecules to turn on and off nerve cells in the deep brain structure of mice.
They were not hot enough -- like stars-- to give off light.

Soon after a light sell-off began, more pressure was added to the euro when the European Central Bank (ECB) reported that M3 Money Supply remained steady at 0.2% growth.

These slightly deeper quartz grooves result in light-wave phases that are slightly off-kilter from the light waves that pass through shallower grooves.

起燃
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.
試驗(yàn)表明二次空氣可以縮短催化器起燃時(shí)間,有效地降低冷起動(dòng)過程中HC和CO排放。
