This paper introduces the design concept of double closed-loopratio control system as well as the design and the application about acetylene with hydrochloride in chloroethylene synthesis unit.
Vehicles spend a period of time in an Open Loop air-fuel ratio programming until the oxygen sensors heat up to proper operating temperature of approximately 316 degrees Celsius.
汽车需要在开环空燃比程序上花费一段时间以达到氧传感器的工作温度大约为316摄氏度。
