要特别注意冷却系统的正常运行，冷却水、电瓶水、机油夏季蒸发较快，要及时检查，及时补充，尽量避免超负荷运行，同时应换用高黏度的润滑油，并适当缩短换油周期。电子元件高温下经常会发生车辆自燃的情况，其中电子元件短路是造成车辆自燃的一个重要原因，所以在行车过程中，一旦发现车辆电子元件出现问题，一定要及时检查，不可忽视。水箱高温天气行车，大运运隆6方搅拌车 水箱内的冷却水蒸发加快，发现缺水时要立即停车，等怠速运转降温后再补充冷却水，注意开水箱盖防烫伤。此外，还要注意散热器是否有灰尘等脏东西造成堵塞，电风扇是否运转正常等。
Pay special attention to the normal operation of the cooling system. The cooling water, battery water and engine oil evaporate quickly in summer. Check and supplement in time to avoid overload operation as much as possible. At the same time, replace with high viscosity lubricating oil and shorten the oil change period appropriately. Autoignition of vehicles often occurs under high temperature of electronic components, and the short circuit of electronic components is an important cause of autoignition of vehicles. Therefore, in the process of driving, once the problem of vehicle electronic components is found, it must be checked in time, which cannot be ignored. When the water tank is driven in high temperature, the cooling water in the water tank of the 6-side mixing truck of Dayun Yunlong will evaporate faster. If there is a shortage of water, stop immediately, and replenish the cooling water after the idle operation is cooled. Pay attention to opening the water tank cover to prevent scalding. In addition, pay attention to whether the radiator is blocked by dirt such as dust, and whether the electric fan operates normally.
发现发动机过热时，一定要停车检修，以防产生爆缸等严重问题。轮胎爆胎是大热天开车时更可怕的事情，因此经常检查轮胎气压尤其重要。轮胎气压不合适，很容易发生爆胎危险。准备一个“气压表”就非常方便。一般来说，冷车气压值约在，热车升高属于正常。空调高温下空调的使用必不可少。很多人认为制冷剂加得越多，制冷效果越好，其实不然。量要适中才好，过少或者过多，都会影响制冷效果。应严格按照维修手册上的规定和技术参数来加制冷剂。此外，要保证空调管道畅通，空气滤网要定时检查、清洗、更换。
When the engine is found to be overheated, it must be stopped for maintenance to prevent serious problems such as cylinder explosion. A tire blowout is the most terrible thing when driving in hot weather, so it is particularly important to check the tire pressure frequently. The tire pressure is not appropriate, which is easy to cause the risk of tire blowout. It is very convenient to prepare a "barometer". Generally speaking, the air pressure of the cold car is about, and the rise of the hot car is normal. The use of air conditioning under high temperature is essential. Many people think that the more refrigerant is added, the better the cooling effect is. The amount should be moderate. Too little or too much will affect the cooling effect. The refrigerant shall be added in strict accordance with the regulations and technical parameters in the maintenance manual. In addition, the air conditioning pipeline shall be ensured to be unblocked, and the air filter screen shall be regularly inspected, cleaned and replaced.
炎热的天气里混凝土搅拌车车的确容易出现故障，但只要平时多加留心并定期保养，就不会出大问题。天气酷热时，水温表如果显示在９０℃以上，只要报警灯不亮，冷却系统就属于正常。汽车电系中存在着多种形式的电磁干扰源，干扰电磁波通过传导和辐射对车载电了设备产生不同程度的干扰。汽车电系内产生干扰电磁波更强的是火花点火系统。所以，分析研究火花点火系统电磁干扰的形成机理，重汽牌6方搅拌车采取切实有效的抑制措施，提高火花点火系统的电磁兼容性设计是尤为重要的。点火系统的电磁干扰主要来源于高压点火线、火花塞和点火线圈等儿个部件。
The concrete mixer truck is prone to failure in hot weather, but as long as you pay more attention and maintain it regularly, it will not cause major problems. If the water temperature gauge shows above 90 ℃ in extremely hot weather, the cooling system is normal as long as the alarm light is off. There are many kinds of electromagnetic interference sources in the automobile electrical system. The interference electromagnetic waves cause different degrees of interference to the on-board electrical equipment through conduction and radiation. Spark ignition system has the strongest interference electromagnetic wave in the automobile electrical system. Therefore, it is particularly important to analyze and study the formation mechanism of electromagnetic interference of spark ignition system, and take effective suppression measures to improve the electromagnetic compatibility design of spark ignition system. The electromagnetic interference of the ignition system mainly comes from the high-voltage ignition wire, spark plug, ignition coil and other components.
当次级电路电压达到火花塞气隙击穿电压时，火花塞问隙被击穿，储存于火花塞分布电容中的能量迅速释放，放电时问极短，仅数微秒，但形成的放电电流则非常大，可达几十安培，这个过程称为电容放电过程。这一阶段的放电使次级电路的电压和电流形成陡峭的脉冲形式，这种宽带脉冲通过裸露的高压点火线对外辐射电磁波，造成周围环境的电磁干扰。汽车电系内产生干扰电磁波更强的是火花点火系统。所以，分析研究火花点火系统电磁干扰的形成机理，采取切实有效的抑制措施，提高火花点火系统的电磁兼容性设计是尤为重要的。
When the secondary circuit voltage reaches the spark plug gap breakdown voltage, the spark plug gap is broken down, and the energy stored in the spark plug distribution capacitor is released rapidly. The discharge time is very short, only a few microseconds, but the resulting discharge current is very large, up to tens of amperes. This process is called capacitance discharge process. The discharge at this stage makes the voltage and current of the secondary circuit form a steep pulse form. This broadband pulse radiates electromagnetic waves through the exposed high-voltage ignition line, causing electromagnetic interference in the surrounding environment. Spark ignition system has the strongest interference electromagnetic wave in the automobile electrical system. Therefore, it is particularly important to analyze and study the formation mechanism of electromagnetic interference of spark ignition system, take practical and effective suppression measures, and improve the electromagnetic compatibility design of spark ignition system.

随后，另一部分储藏在次级线圈电感中的能量将维持放电，其特点是时问较长，为几毫秒，放电电流约几十毫安，这一过程称为电感放电(火花尾)，该电流使气缸内的燃料得到充分燃烧，以保证点火可靠。可见需要抑制的是阶段的电容放电电流，该电流为宽带脉冲电流，带宽在甚更高频无线电的主要干扰源。由于搅拌车火花塞高压放电引起的电磁干扰主要是通过高压点火线向外辐射的，因此高压点火线此时成为干扰源的发射天线。天线的辐射功率与天线的激励电流的平方成正比，也就是说高压点火线上的电流越大，对外辐射的功率也就越大，造成的电磁干扰越强。因此通过减小高压线上的点火电流，可从源头上抑制点火系统对外的电磁干扰。
Then, another part of the energy stored in the secondary coil inductance will maintain the discharge, which is characterized by a long time interval of several milliseconds and a discharge current of about tens of milliamperes. This process is called inductive discharge (spark tail). This current makes the fuel in the cylinder fully burn to ensure reliable ignition. It can be seen that the capacitor discharge current in the first stage needs to be suppressed. This current is a broadband pulse current, which is the main interference source of even higher frequency radio. Because the electromagnetic interference caused by the high-voltage discharge of the spark plug of the mixer is mainly radiated outward through the high-voltage ignition line, the high-voltage ignition line now becomes the transmitting antenna of the interference source. The radiation power of the antenna is proportional to the square of the excitation current of the antenna. That is to say, the greater the current on the high-voltage ignition line, the greater the external radiation power, and the stronger the electromagnetic interference. Therefore, by reducing the ignition current on the high-voltage line, the external electromagnetic interference of the ignition system can be suppressed from the source.
