Composition and working principle of air intake system?
The air intake system consists of an air filter, an air flowmeter, an intake pressure sensor, a throttle body, an additional air valve, an idle speed control valve, a resonant cavity, a power cavity and an intake manifold.
2. Working principle
When the engine is working, the driver controls the opening of the accelerator through the accelerator pedal, thus changing the air intake and controlling the operation of the engine. After the air entering the engine is filtered by the air cleaner to remove impurities such as dust, it flows through the air flowmeter, enters the power room along the throttle passage, and is distributed to each cylinder through the intake manifold; When the engine is idling, some air bypasses the throttle and enters the cylinder through the additional air valve or idling control valve.
