Mass flow sensor

Mass (air) flow sensor (MAF) digunakan untuk mengetahui debit massa udara yang masuk mesin pembakaran internal bahan bakar injeksi.

Informasi massa udara yang diperlukan untuk unit kontrol mesin (ECU) untuk menyeimbangkan dan memberikan massa bahan bakar yang benar untuk mesin. Air berubah densitasnya karena memperluas dan kontrak dengan suhu dan tekanan. Dalam aplikasi otomotif, kerapatan udara bervariasi dengan suhu lingkungan, ketinggian dan penggunaan induksi paksa, yang berarti bahwa sensor aliran massa lebih tepat daripada sensor aliran volumetrik untuk menentukan jumlah udara masuk di setiap silinder. (Lihat stoikiometri dan hukum gas ideal.)
