Back Next Part Ⅲ Reading Passage Four Motronic Engine-management System The heart of the Motronic system is an electronic control unit (ECU) consisting of microprocessor and a memory. The memory contains a work program with data for determining the injection amount and the moment of ignition. Back Next Part Ⅲ Reading Passage Four Motronic Engine-management System CAN -Controller AreaNetwork 域网络控制器 The ECU determines which air/fuel ratio the engine runs at based upon engine conditions monitored by input sensors and the program stored in its memory. Back Next Part Ⅲ Reading Passage Four Motronic Engine-management System Sensors provide the microprocessor with information on the amount of intake air, engine speed, crankshaft position, the intake air temperature, the engine coolant temperatures, and more. Back Next Part Ⅲ Reading Passage Four Motronic Engine-management System The sensors are, basically, mass air flow sensor, crankshaft position sensor, camshaft position sensor, throttle position sensor, engine coolant temperature sensor, intake air temperature sensor, oxygen sensor, and knock sensor.
