全自动搅拌车在高温下的两点异常

来源:https://www.jfjiaobanche.com 浏览:发表时间:2022-12-02
在炎炎夏日,因为外部平均气温高,全自动搅拌车发动机冷冻液与空气温度差缩小,造成制冷系统制热量缩小,使发动机过热,进而会出現一系列的难题。下面全自动搅拌车厂家给您讲解一番。
In the hot summer, due to the high average external temperature, the temperature difference between the engine coolant and the air of the fully automatic mixer truck shrinks, resulting in the reduction of the heating capacity of the refrigeration system and the overheating of the engine, which will lead to a series of problems. Next, the manufacturer of the automatic mixer will explain it to you.
全自动搅拌车发动机的打气指数降低:
The pumping index of the engine of the fully automatic mixer decreases:
平均气温越高,空气的密度越小,发动机的具体进气口量少。因为发动机过热,发动机罩内温度高些,发动机打气工作能力减少,均使打气指数降低。进而导致发动机输出功率降低,以至轿车行车乏力。另外混合气体相对性浓稠,尾气排放废气排放中的有害物浓度值扩大,加剧空气污染。
The higher the average temperature is, the smaller the air density is, and the specific air intake of the engine is less. Because the engine is overheated, the temperature in the engine hood is higher, and the engine's pumping capacity is reduced, the pumping index is reduced. This in turn leads to a reduction in the engine output power, resulting in a lack of driving power for cars. In addition, the mixed gas is relatively thick, which increases the concentration of harmful substances in the exhaust gas emissions and aggravates air pollution.

全自动搅拌车发动机点燃异常:
Abnormal ignition of the engine of the automatic mixer:
空气温度高,进到气缸的混和温度也高,造成发动机的温度提高,而热管散热器的排热高且效率低,发动机处在超温情况,发动机燃烧室内未燃混合气体接纳发热量多,加剧焰前反映,非常容易造成燃爆。另外积存于发动机燃烧室内各构件上的积碳产生炽热点,易造成异常的点燃,加剧了发动机的超温,产生的两极化,使之相关部伯造成热形变乃至裂痕毁坏。
The high temperature of the air leads to the high mixing temperature of the air entering the cylinder, which increases the temperature of the engine. However, the heat pipe radiator has high heat removal efficiency and low efficiency. The engine is in the over temperature condition. The unburned mixed gas in the engine combustion chamber receives more heat, which aggravates the reaction before the flame, which is very easy to cause combustion and explosion. In addition, the carbon deposits accumulated on various components in the engine combustion chamber produce hot spots, which are easy to cause abnormal ignition, and aggravate the engine's overheating, resulting in polarization, causing thermal deformation and even crack damage to the relevant parts.
在高溫自然环境里,全自动搅拌车发动机制冷系统的排热温度差小,排热能力较差,发动机非常容易超温。所以日常使用要及时检查各种事项以及零部件的使用。更多相关内容就来我们网站https://www.jfjiaobanche.com了解吧!
In the high temperature natural environment, the engine refrigeration system of the fully automatic mixer has a small heat removal temperature difference, poor heat removal capacity, and the engine is very easy to overheat. Therefore, in daily use, various items and the use of parts should be checked in time. More relevant content will come to our website https://www.jfjiaobanche.com Understand!
