Study on Unburned Hydrocarbon Emissions from Diesel Engine During Warm-up Period

柴油机 暖车 阶段未燃碳氢排放影响因素的研究

Compared with cold start it can reduce the idling warm-up period by 90 % and the fuel consumption in one start by about 0.4L .

与冷启动相比，可使怠速 暖机 时间缩短90%，每次启动可降低耗油量约0.4L；

This was just a warm-up to the pre-Christmas period Berger explained when the brasserie would seat 250 and their 30-seater private room would be full as well .

伯杰解释道，这只是圣诞节前的 热身 阶段，到圣诞节前时，餐馆的座位将达到250个，他们容纳30位客人的包间也是座无虚席。

Following this warm-up period the throttle plate remains open in normal driving so there 's no low-pressure area in the manifold impeding the engine 's ability to pump air .

紧跟这个 暖 升 期间，正常驾驶时节流板保持打开，所以没有歧管阻碍发动机泵空气行为的低压区。

This software can make the numerical simulation and testing research for catalyst converter during warm-up period .

运用该软件，对催化转化装置的 温 升 过程开展了数值模拟和试验研究。
