4. The lowering hermetical state of an engine will not only cause economy and power coastdown, but also worsen the emission evaluating indicators of exhaust gas.
5. The applied examples show that the magnetic coupler can achieve the non-contacting and hermetical drive without any leakage under the condition of high-pressure, ultrahigh-pressure, vacuum, etc.
