混凝土搅拌车冬季为什么油耗大?

所属分类:公司新闻 发布时间:2022-11-11 来源:http://www.shanqijituan.cn/ 浏览量:18

冬季搅拌车增加油耗原因一:发动机燃烧稳定性和效率变差.
The first reason for the increase of fuel consumption in winter: the engine combustion stability and efficiency become worse
冬天气温低,冷空气遇到冷的燃油会造成发动机燃烧稳定性和效率变得差:因为低温使柴油比重变大,会喷得更远,所以柴油雾化颗粒和缸壁碰撞机会更大(整个燃烧室燃烧效率低的就是缸壁);同时,低温空气会使燃烧压力和燃烧温度降低。
In winter, when the temperature is low, cold air meets cold fuel, which will lead to poor combustion stability and efficiency of the engine: because the low temperature makes the proportion of diesel fuel larger, it will spray farther, so diesel atomized particles have a greater chance to collide with the cylinder wall (the cylinder wall is the one with low combustion efficiency in the whole combustion chamber); At the same time, low temperature air will reduce the combustion pressure and combustion temperature.
一般电控柴油机在低温环境下启动以后会有一个低温保护措施:提高怠速,有的车此时踩油门会没有反应。
Generally, after starting an electronically controlled diesel engine in a low temperature environment, there will be a low temperature protection measure: increase the idle speed, and some cars will not respond when stepping on the accelerator.
冬季增加油耗原因二:发动机进入正常工作水温的时间会长
The second reason for increasing fuel consumption in winter is that the engine takes a long time to enter the normal operating water temperature
寒冷的气温条件下发动机进入正常工作水温的时间也会变长,在发动机水温逐渐升高的过程中,油耗是随温度升高而降低的,这个时间的变长意味着总油耗也会变大。
Under cold temperature conditions, the time for the engine to enter the normal operating water temperature will also be longer. When the engine water temperature gradually increases, the fuel consumption will decrease with the increase of temperature. A longer time means that the total fuel consumption will also increase.
须说明一点:提高水温就是提高缸壁温度,要想充分节油就不能让水温(缸壁温度)太低,不管是什么季节。
It must be noted that increasing the water temperature means increasing the cylinder wall temperature. In order to fully save oil, the water temperature (cylinder wall temperature) must not be too low, no matter what season it is.
冬季增加油耗原因三:机油的选用是否正确
The third reason for increasing fuel consumption in winter: whether the selection of engine oil is correct
北方进入九月份以后专用车的各种油液也要改用冬季的了。对于机油我的建议是:拿出你的发动机使用手册看上面对于机油和气温环境的对应使用条件。
After September in the north, all kinds of oil for special vehicles will also be used in winter. My suggestion for engine oil is: take out your engine manual and read the corresponding operating conditions for engine oil and temperature environment.
一般现在使用的都是冬夏通用机油,也叫多级机油。我们知道后面的数字30.40.50是粘度等级,前面的数字0、5、10、15都是指的是冬天相对应气温下的粘度等级,用-35℃摄氏度加上前面的数字就是可以使用的气温。
Generally, the engine oil used now is general oil for winter and summer, also called multi-stage oil. We know that the following figure 30.40.50 is the viscosity grade, and the preceding figures 0, 5, 10 and 15 refer to the viscosity grade at the corresponding temperature in winter. The temperature that can be used is - 35 ℃ Celsius plus the preceding figure.
