Sometimes it seems that there is nothing we can do about the solenoid valve for automatic transmission. Because we have no standard to evaluate its merits and demerits, and sometimes the faults caused by it are intermittent, we often feel puzzled. I think for the solenoid valve, we should regard it as another working mode of the fuel injection nozzle, because the faults caused by the fuel injection nozzle and the solenoid valve are all non blocking and leakage.

可是喷油嘴导致的結果我们可以根据剖析柴油发动机的短期内和长期性汽柴油调节值来多方面明确。假如长期性汽柴油调节超出百分之二十＋10，就表明油泵汽压过低或喷油嘴阻塞。

However, the results caused by fuel injection nozzle can be determined in many aspects according to the analysis of diesel engine short-term and long-term gasoline and diesel regulation values. If the long-term regulation of gasoline and diesel oil exceeds 20% and 10%, it indicates that the steam pressure of oil pump is too low or the fuel injection nozzle is blocked.

假如待速时短期内汽柴油调节超出百分之二十－10，则表明油泵汽压过高或某些喷油嘴泄露。喷油嘴相匹配柴油发动机电脑上的相对控制精度应当低于0.01ms。

If the adjustment of gasoline and diesel oil exceeds 20-10% in a short period of time when the speed is waiting, it indicates that the steam pressure of the oil pump is too high or some fuel injection nozzles are leaking. The relative control accuracy of the computer should be less than 0.01ms.

尽管我们不能像看待喷油嘴那般的分辨出故障的缘故，我不知道变速器电脑上相对电磁阀的控制精度是不是比喷油嘴高（应该是电磁阀要比喷油嘴的控制精度低，由于换挡全过程是以秒为企业测算的，压摆率电磁阀的操纵頻率一般是60HZ），可是大家开的是一样的，应用超声清洗机清理40分钟。由于导致故障的缘故是同样的：

Although we can't distinguish the fault as we look at the fuel injection nozzle, I don't know whether the control accuracy of the solenoid valve on the transmission computer is higher than that of the fuel injection nozzle (it should be that the control accuracy of the solenoid valve is lower than that of the fuel injection nozzle, because the whole shift process is measured by the enterprise in seconds, and the operating frequency of the yaw rate solenoid valve is generally 60Hz), but we have the same opening, The ultrasonic cleaning machine was used for 40 minutes. As the cause of the failure is the same:

全是被损坏并环境污染导致的，因此同样。01N电磁阀由于构造所至，不仅存有环境污染，有可能也有闸阀的损坏，因此清理以后要用其他方式 做进一步评定。01V的电磁阀则是存有于电磁阀內部的损坏残渣难以除去，因此大家应用车用汽油做为清洁剂，而且清理40分钟之上。

It's all caused by damage and environmental pollution, so it's the same. Due to the structure of 01N solenoid valve, there is not only environmental pollution, but also damage of gate valve. Therefore, after cleaning, further assessment should be made by other methods. 01v solenoid valve is stored in the solenoid valve internal damage residue is difficult to remove, so we use car gasoline as a cleaning agent, and clean up for 40 minutes.
