What do you think of the choice of automobile air flowmeter?

The air flow meter in the vehicle is actually a sensor, which is usually called mass air flow sensor or MAF sensor. It is an important part of computer system, which is found in most modern vehicles. This sensor has the greatest impact on your gasoline economy. This compares with all other electronic components in your car.

When your MAF fails, it is likely to throw out codes and light up your dashboard lights. You may encounter unstable idle speed, hesitant engine, insufficient power and poor mileage. This may be a signal that you need to upgrade or replace. This article will let you know the idea and importance of having a well-functioning air flowmeter, its working principle and where to find a substitute.

There are two types of air flow meters. The first is the vane type, sometimes called VAF, or volume air flow sensor. VAF is an older type, which is not common in newer models of vehicles. It will use doors or baffles to measure the resistance of airflow through the wings found in the airflow. The resistance is determined by air density, air speed and the shape of the sensor.

The second and most commonly used air flowmeter is MAF sensor. The MAF sensor uses the fire line to determine the air flow entering the air intake. This heating wire is suspended in the airflow of the engine. The resistance of the wire will increase with the temperature of the wire. This in turn will cause the current flowing through the circuit to fluctuate.

Then, the computer in the vehicle uses this information to determine the ideal air-fuel ratio. If the sensor fails, you may notice unstable idle speed, poor fuel consumption and even find yourself stalling. There is also a cold wire version of the MAF sensor. This is similar to the MAF hotline. The difference is that in addition to thermal resistance, it also uses cold resistance to provide a more accurate reference point.

Most cars can usually use standard MAF sensors. Others are looking for performance improvements, and upgrades can help achieve this goal. Another reason for installing the MAF sensor is that if you are upgrading from the carburetor system to the fuel injection system.

Generally speaking, the upgraded MAF sensor will need a larger diameter than the parts in stock. A larger MAF sensor diameter allows more horsepower to be generated. This is because it allows more airflow into the engine. Therefore, more airflow allows more fuel to burn.

The upgrade of this component provides you with a more accurate and calibrated metering airflow than the original inventory component. Improve the performance of modified vehicles that need higher oil-gas ratio. To further improve your horsepower, please pair the upgraded MAF sensor with the aftermarket throttle body and cold air intake system.
