- The mass air flow (MAF) sensor measures the mass of the air entering the engine. Because air mass varies with air temperature (cold air is denser than warm air), measuring air mass provides the PCM with a very acurate way of determining the correct amount of fuel to obtain the ideal fuel/air mixture.fter you clean the mass air flow sensor make sure to reset the check engine light. You can reset your check engine by going to Auto Zone or Kragen Auto Parts and ask to borrow the code reader* (it's free all you need is your ID and credit card) to check out the code reader.

- 5.1.1 Geostrophic winds -- Newton's Second Law says that the force acting on an object equals the product of its mass and its acceleration. One force acting on an air parcel is the pressure gradient force: that force that causes acceleration from higher pressure to lower pressure. As an analogy, consider the pressure gradient that exists at the nozzle of your vacuum cleaner when it is turned on.

Pressurization Basics How much mass flow exits through the leaks depends upon ∆P. If there is a low ∆P, then the push that causes air to flow through the leak hole is small and hence the flow is small. But when ∆P is large, then the mass flow across the leak is also large, even though the leak size has not changed.

Hadley Cell The Hadley Cell involves air rising near the equator, flowing toward the North and South Poles, returning to the surface of the Earth in the subtropics, and flowing back toward the equator at the surface of the Earth.This produces winds called the trade winds and the tropical easterlies.n the Hadley cell, air rises up into the atmosphere at or near the equator, flows toward the poles above the surface of the Earth, returns to the Earth s surface in the subtropics, and flows back towards the equator. This flow of air occurs because the Sun heats air at the Earth s surface near the equator.

Mass Air Flow Sensor Vane Air Flow Meters. A vane air flow meter (also known as a “flap style” meter and a VAF sensor) is an early type of air flow meter that measures air intake volume. This type of meter uses a spring-loaded flap that is attached to a variable resistor. As air enters, it pushes against the flap or plate opening it.

Mass Air Flow Sensor (MAF) A Mass Airflow Sensor (MAF) is one of the components of a car electronic fuel injection system. A mass air flow sensor is installed between the air filter and the intake manifold of the engine. The main job of the mass air flow sensor is to measure the amount of air entering the engine or air flow.Often an intake air temperature sensor (IAT) is also installed within the mass air flow sensor. There are few types of air flow sensors, however most modern cars use a hot-wire type.Let's see how it works.he main job of the mass air flow sensor is to measure the amount of air entering the engine or air flow.

Ferrea Helps Explain Valve-flow Dynamics If we accept that airspeed and net mass flow are the key components of cylinder filling, it’s easy to see that moving high-velocity air past the valve and into the combustion chamber smoothly with minimal turbulence is critical to optimizing performance.

- If an air mass is warmer than the surface over which it is passing it receives the designation, w. For example, if a continental polar air mass (cP) moves out over the warm water, it becomes (cPk). An air mass’s stability can be assessed by weather it is colder or warmer than the surface over which it is passing. maritime tropical – mT ο maritime polar – mP AIR MASS MODIFICATION Once an air mass moves out from its region of origin, it can become modified by the surface over which it is passing. If an air mass is colder than the surface over which it is passing it receives the designation, k.

What Does a Performance Mass Air Flow Sensor Do? What Does a Mass Air flow Sensor Do? Your mass air flow sensor or “MAF” detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the computer can then direct fuel injectors to add more or less gasoline to the air/fuel mixture.

Mass Air Flow Sensor (MAF) Cleaning Clean the MAF sensor. Spray 10 to 15 spurts of the cleaner onto the wire or plate. A Mass Air Flow (MAF) sensor monitors the temperature and weight of air entering your engine.Your onboard computer needs that information to calculate the right amount of fuel for all engine operating conditions.ere's how: Before going to the store, pull off the air duct between the air filter box and the throttle body to see how the MAF sensor is anchored. If you see Torx screws, buy a Torx tool and a can of CRC Mass Air Flow Sensor Cleaner. Don't use any other cleaners; they can ruin the MAF.

Venturi effect However, mass flow rate for a compressible fluid can increase with increased upstream pressure, which will increase the density of the fluid through the constriction (though the velocity will remain constant). This is the principle of operation of a de Laval nozzle.
