What is an air mass meter (AFM), how to recognize and what it does?
Did you know that you can go the gas pedal in a car as fast, in order to push more air and fuel into the engine allows. All this happens under the hood or cap, but how is it regulated? Well, the AFM is an important part in regulating the amount of fuel in a modern car engine is injected, so that all modern petrol and diesel, an AFM.
As you go faster (the foot) 'sAFM believes that more air flows and the brain tells the engine (ECU), which has more then the fuel injectors. And 'some' as a hill or run faster, your brain recognizes the muscles need more oxygen, increases heart rate and breathing faster.
Engines with carburetor (remember those?) Not AFM, because the same gasifier regulates the amount of fuel and air into the engine. So if your engine management panel for an error in the AFM, it is necessarysearch and replace. This can often be performed without special tools and with a little '.. "Savvy", common sense and a workshop manual
Pay attention to the air intake to the engine. This is usually made of plastic, shaped like a little 'just like a trumpet. Follow the air filter and, in general, the AFM will be the filter box, or cut the pipe to find the engine.
Most AFMs have a 12-volt (not dangerous) electrical sockets in them, which is slightlyseparately.
What are the different types of MAF are used in modern cars and how they work?
The first type of AFM (eg Bosch Jetronic) used a bucket or flap inside the meter body as the air is above the door is open. A spring then the flap towards a closed position when the engine slows down. This type of flag to make it cumbersome and expensive. Following the mode of AFM sensors are often called air flow and work on a hot wire air flow (through the wire) is measuredthe electricity needed to keep one of the wires at a given temperature. Looking in and you can usually see two filaments, they must be thin to accurately measure the speed of the air flowing into the engine.
Which companies make the mass air meter? There are sample copies on the market? Equipment installed on the car is used by European companies such as Bosch, Siemens and Hella, and yes, there are a lot of copies of the models on the market. Depending on your budgetYou can also mount a proper replacement.
How will you know if your MAF has failed and the impact of errors on the performance of your car? The simplest statement is, of course, the error light on the dashboard shows! In general, the car will start but will run unevenly, and can also be cut, with more fuel and poor implementation.
How easy is it to change the airflow meter itself?
Fortunately, there is an easy job and requires no special skills or tools. OftenThe instrument is easy to shoot or find Torx or Allen screws.
