Precision air flow quantity dosing device for internal combustion engine

摘要

The dosing device delivers an air stream with a defined flow quantity using air flow devices (2,3,4,16) with two air openings (24,26) and five parallel flow paths (4a-4d,16) between them. Four of the flow paths contain non-adjustable flow control valves (5) and are selectively blocked. The other flow path (16) contains a continuously adjustable flow quantity dosing device (20,21) and a flow measuring device (17,18,19).
