What is the working principle of the air supply system?

The working principle of the air supply system is: air passes through the intake channel and the air flow meter. The sensor of the air flow meter outputs a voltage signal under the action of airflow pressure and transmits this voltage signal to the ECU. The ECU determines the basic fuel injection quantity based on this signal and other signals such as engine speed. The function of the air supply system is to provide clean air for the engine and control the exhaust volume during normal operation. The air supply system consists of an air metering device, idle speed control valve, supplementary air valve, inertia supercharging intake system, throttle position sensor, intake temperature sensor, etc.
The working principle of the air supply system is essentially to allow the engine to properly intake fresh air for the combustion of fuel. When the engine is running, air is drawn in through the intake at the front of the vehicle, first passing through the air filter to remove dust and impurities, ensuring clean air enters the system. Then, the air flows through the intake pipe to the throttle body, which is controlled electronically or mechanically to open and close, regulating the amount of air to meet acceleration or idle requirements. After entering the intake manifold, the air is distributed to each cylinder, where it mixes with fuel and is ignited to generate power. The entire system must operate smoothly and efficiently to ensure low fuel consumption and reduced emissions. If any part of the system becomes clogged or damaged, such as a dirty air filter reducing airflow, it can cause engine shaking or increased fuel consumption. Drivers should remember to regularly inspect the air filter, clean or replace it as needed, to keep the vehicle running smoothly.
The working principle of the air supply system mainly revolves around the mechanism by which the engine draws in air. Simply put, it intakes air from the outside, purifies it through the air filter, regulates the airflow via the throttle, and then distributes it to the cylinders for fuel combustion. This process directly affects the vehicle's performance: sufficient air intake and uniform mixing result in quicker engine response and more powerful acceleration. Conversely, if the air ducts are dirty or damaged, causing air leaks, you may experience reduced power, increased noise, or excessive emissions. Many modern vehicles now employ electronic throttle control and turbocharging technology to make air intake more precise and efficient. On long drives, I pay special attention to this system because dust accumulation is common, and a clogged air filter can impact fuel economy. Therefore, it's advisable to keep the engine bay clean when parked and regularly check the tightness of air duct connections. Paying attention to these details ensures smoother and more worry-free driving.
