The air-fuel mixture is determined by your car's _________.
Fuel Filter.
Exhaust manifold.
Fuel injector.
Detailed Explanation
The air-fuel mixture in a car's engine is determined by the Engine Control Module (ECM), also known as the Engine Control Unit (ECU) or Powertrain Control Module (PCM). The ECM is an electronic control module that monitors various engine parameters, such as engine speed, throttle position, oxygen sensor readings, and coolant temperature. Based on these inputs, the ECM calculates the appropriate fuel injection duration and ignition timing to achieve the desired air-fuel ratio for optimal engine performance and efficiency. The ECM continuously adjusts the air-fuel mixture to maintain proper combustion and meet emissions regulations.
