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.

可是噴油嘴導致的結果我們可以根據剖析柴油發動機的短期內和長期性汽柴油調節值來多方面明確。假如長期性汽柴油調節超出百分之二十＋10，就表明油泵汽壓過低或噴油嘴阻塞。

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.

假如待速時短期內汽柴油調節超出百分之二十－10，則表明油泵汽壓過高或某些噴油嘴泄露。噴油嘴相匹配柴油發動機電腦上的相對控制精度應當低于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.

盡管我們不能像看待噴油嘴那般的分辨出故障的緣故，我不知道變速器電腦上相對電磁閥的控制精度是不是比噴油嘴高（應該是電磁閥要比噴油嘴的控制精度低，由于換擋全過程是以秒為企業測算的，壓擺率電磁閥的操縱頻率一般是60HZ），可是大家開的是一樣的，應用超聲清洗機清理40分鐘。由于導致故障的緣故是同樣的：

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:

全是被損壞并環境污染導致的，因此同樣。01N電磁閥由于構造所至，不僅存有環境污染，有可能也有閘閥的損壞，因此清理以后要用其他方式 做進一步評定。01V的電磁閥則是存有于電磁閥內部的損壞殘渣難以除去，因此大家應用車用汽油做為清潔劑，而且清理40分鐘之上。

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.
