Air Intake Duct 13717571348 B For BMW F01 F02 E71

The main difference between automobile intake pipe without sensor and with sensor lies in whether it has the function and application of sensor.

1. Intake pipe without sensor: The traditional automobile intake pipe usually has no sensor, and its main function is to introduce air into the engine for combustion. This kind of intake pipe is usually a simple pipe structure, and there is no electronic component with integrated sensor. Its main function is to provide air flow and pressure to meet the combustion requirements of the engine.

2. Intake pipe with sensor: Modern automobile intake pipe usually integrates various sensors to monitor and control the working state of the engine. These sensors can measure air flow, air temperature, intake pressure and other parameters, and transmit these information to the engine control unit (ECU). According to the data provided by sensors, ECU adjusts parameters such as fuel injection quantity and ignition timing to optimize engine performance and fuel economy.

The intake pipe with sensor can provide more accurate data, so that the engine control system can adjust the fuel supply and ignition timing more accurately to adapt to different working conditions and driving needs. This helps to improve the combustion efficiency of the engine, reduce exhaust emissions and provide a better driving experience.

It should be noted that the types and quantities of intake pipe sensors of different automobile brands and models may be different. Common intake pipe sensors include air flow sensor (MAF), air temperature sensor (IAT) and intake pressure sensor (MAP). The specific applications and functions of these sensors may be different depending on vehicle models and engine types.
