For the solenoid valve specialized in automatic transmission, sometimes it seems that there is nothing we can do, because we do not have the standard to evaluate its advantages and disadvantages, sometimes it causes intermittent faults, which often makes us feel confused. I think for the solenoid valve, we should regard it as another working mode of the fuel injector, because the faults caused by the fuel injector and solenoid valve are no 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。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。

However, the results caused by the fuel injection nozzle can be determined in many aspects according to the analysis of the short-term and long-term adjustment values of the diesel engine. If the long-term adjustment of gasoline and diesel exceeds 20% + 10%, it indicates that the steam pressure of oil pump is too low or the nozzle is blocked. If the adjustment of gasoline and diesel exceeds 20-10% in a short time, it indicates that the steam pressure of oil pump is too high or some fuel injection nozzles leak. The relative control accuracy of the matching diesel engine should be less than 0.01ms.

Automatic transmission maintenance

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 tell the cause of the fault as we think of the fuel injector, I don't know whether the control accuracy of the solenoid valve on the transmission computer is higher than that of the fuel injector (it should be that the control accuracy of the solenoid valve is lower than that of the fuel injector, 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), Clean with ultrasonic cleaner for 40 minutes. 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 are not only environmental pollution, but also gate valve damage. Therefore, after cleaning, further evaluation should be made by other methods. 01 V solenoid valve is stored in the solenoid valve internal damage residue is difficult to remove, so we use car gasoline as cleaning agent, and clean more than 40 minutes.
