Once inside, the system channels the incoming air towards the engine’s intake manifold. The manifold is responsible for evenly distributing the air to each cylinder for combustion.
- Regulates airflow.
To maintain optimal performance, the airflow needs to be regulated. This is where components like the throttle body and valves come into play. The throttle body controls the amount of air entering the engine based on driver input, while valves adjust and direct airflow as needed.
By efficiently managing the flow of air, a well-functioning air intake system ensures that an appropriate amount of oxygen reaches the engine, allowing for efficient fuel combustion and power generation.
Main parts of air intake system.
Air filter, mass flow sensor and throttle body are the main component parts of air intake system. The air intake system is a crucial component of an engine, responsible for delivering the necessary oxygen to support combustion. It consists of several main parts that work together to ensure optimal performance.
- Air filter.
The air filter is a vital part of the air intake system as it removes impurities from incoming air before it enters the engine. By preventing dust, dirt, and other particles from reaching the engine, it helps maintain its efficiency and longevity.
- Mass flow sensor.
Another essential component is the mass flow sensor. This sensor measures the amount of incoming air and relays this information to the engine control unit (ECU). The ECU then adjusts fuel injection accordingly to ensure optimal combustion.
- Throttle body.
The throttle body controls the airflow into the engine. It acts as a gateway between the air intake manifold and the engine bay. By adjusting the position of its internal flap or valve, it regulates how much air enters the cylinders, allowing for precise control over power output.
Different types of air intake systems for cars.
Stock or integrated systems, short ram intakes and aftermarket cold air intake options, are the different types of air intake systems available for cars. Each of the different type of air intake system has its pros and cons.
- Stock or integrated systems.
These are the factory-installed standard setups found in most vehicles. They come with a specific type of air intake system already installed. The stock or integrated systems are the standard setups that come with your vehicle from the factory. These systems are designed to meet general performance requirements and may not offer significant enhancements.

On the other hand, short ram intakes provide increased airflow with shorter tubing. While they may not offer the same cooling benefits as cold air intakes, they still deliver a higher volume of air to the engine, enhancing overall performance.
Overview of mass flow sensors in air intake systems.
The mass airflow sensor measures both the volume and density of incoming air. Mass flow sensors and throttle position sensors work together to optimize power output during vehicle acceleration. This data is then sent to the vehicle’s Engine Control Unit (ECU), enabling precise control over fuel injection.
Types of mass flow sensors.
Hot wire sensors, Vane meters, and Karman vortex sensors are the common types of mass flow sensors used in air intake systems.
- Hot wire sensors.
These sensors use a thin wire heated by an electric current. As the airflow increases, more current flows through the wire, allowing for accurate measurement of mass flow.
- Vane meters.
Vane meters utilize a movable flap that is deflected by the incoming air. By measuring the angle of deflection, these sensors can determine the mass flow rate.
- Karman vortex sensors.
These sensors rely on the principle that when air passes an obstruction, it creates vortices known as Karman vortices. The frequency at which these vortices occur can be measured to calculate mass flow.
Each type of sensor has its advantages and may be suitable for different applications depending on factors such as cost, accuracy requirements, and environmental conditions.
