Description

Mass air flow sensor is installed between the air filter and throttle for measuring the intake air mass of the engine, it decides the basic fuel injection mass and provides an optimal air-fuel ratio for the engine. Therefore, the engine can make the fuel completely burst, and achieve the largest power and reduce emission. Consequently, the automobile can achieve the best performance, and meet the emission limits required by law.

Comparision of the feature with Original

(1) Comparision of static-state feature with Original

In the case of the same air flow, the output signal feature of same model mass air flow sensor is compared with Original.

The comparision results are showed in the follow figure. The abscissa denotes air flow mass, the ordinate denotes output voltage signal. In the figure, the blue curve is output signal of Original, and the red curve is output signal of ours. Through comparing with two curves, it is easy to find that our air flow sensor has the same output signal feature as Original. The same model of our air flow sensor can directly replace Original.

(2) Comparision of dynamic feature with Original

The dynamic feature of mass air flow sensor directly determines whether the engine can quickly accelerate or decelerate or not, or it will be flame-out. The waveform of our air flow sensor and Original is showed in the follow figure, the blue curve is output signal of Original, and the red curve is output signal of ours. It can be found that the rise curve of our air flow sensor coincides with Original, and not appears any overshoot when rising to the top. The dropping curve is also the same. The test results show that our air flow sensor completely reaches the dynamic feature level of Original.

FAQ

(1) Why ofen to replace automobile air flow sensor?

Air flow sensor is a hi-accuracy electronic device which is easy affected by dust, grease, water mist and so on, and its precision also will be reduced after two-three years' use even the OE product or that from the international brands. Consequently, we advise to replace the air flow sensor as the emissions against the limits by law.

(2) Which problem may poor quality air flow sensor cause?

♦Higher fuel consumption, up to 20%.

♦Poor driveability, loss of power/torque.

♦Danger of engine damage, due to excessive lean mixture at full load.

♦Danger of catalytic converter damage.

♦Higher pollutant emissions.

♦Reduce component service life.

The performance comparison table for DOMITE, Original or International brands and Common manufacturers

S/N	Items	Original/ International brands	DOMITE	Common manufacturer
1	Measuring accuracy	≤3%	≤3%	≥5%
2	Response time	≤15ms	≤15ms	≤200ms
3	Plastic	International PBT-GF30	International PBT-GF30	Common PA or PBT with recycling materials which has a pungent smell
4	Appearance	Good	Good	There are spots, coking, floating fibers and burrs on the surface
5	Air intake grid	Grid thickness is ideally designed, moderate degree of airflow blockage, uniformly smooth	Grid thickness is ideally designed, moderate degree of airflow blockage, uniformly smooth	Grid thickness is unreasonable, large degree of airflow blockage, unevenness
6	Metal inserts	Copper, gold plating, oxidation resistance, good electrical conductivity	Copper, gold plating, oxidation resistance, good electrical conductivity	Copper or aluminum, no gold plating, low oxidation resistance, low electrical conductivity
7	Price	High	Medium	Low

Judging from the table, DOMITE'S products have already matched or infinitely reached the quality of the Original or international brands, while common manufacturers' products can't meet the required quality. Our price is quite competitive comparing to the Original or international brands. this is why DOMITE enjoys a fame among large number of clients.
