Selain itu, Karburator Keihin FCR juga dilengkapi dengan teknologi TPS (Throttle Position Sensor), yaitu suatu sensor yang dapat mengukur posisi throttle pada saat berakselerasi. …Now, we're going to try to explain how the darned thing works. The air measuring unit is the venturi, which makes use of a basic law of physics: as the velocity of a gas or liquid increases, the pressure decreases. Warm up engine to normal operating temperature. The partial vacuum caused by increased air speed through the venturi sucks fuel through a jet to mix with the air. The conical angle is normally 21 0 ± 2 0. They were used on 351W police cars with the DS2 ignition system (no ECM) for several years. Berikut penjelasan secara detail tentang spesifikasi karburator yang akan di analisa.

Dari situ, bisa disimpulkan fungsi katup gas adalah untuk mengatur kecepatan aliran udara The fixed-jet carburettor resembles the simpler variable-jet type (See How variable-jet carburettors work) in having a venturi - a constricted neck - through which air flows on its way to the engine. Due to the pressure difference within the Venturi and float chamber, fuel comes out Originally Posted by bubbaf250. © 2023 Google LLC. Udara yang melewati Venturi mengalami peningkatan kecepatan dan penurunan tekanan, yang memungkinkan bahan bakar disedot ke dalam aliran udara untuk membentuk campuran yang mudah terbakar di mesin. To conserve mechanical energy, an increase in the air's speed must be met with a decrease in pressure, and this decrease in pressure is enough to draw fuel from the fuel intake into the airflow. Let us learn more about this concept, which was aptly named the Venturi effect. Besar kecilnya kevakuman yang dihasilkan oleh venturi sesuai dengan kecepatan aliran udara. The Venturi tube provides a handy method for mixing fluids or gases, and is popular in carburetors and atomizers, which use the low pressure region generated at the Variasi lebar venturi ini akan mempengaruhi RPM mesin. …Now, we’re going to try to explain how the darned thing works.
