J-10B with a diverterless air intake displayed at Airshow China 2018. A diverterless supersonic inlet (DSI) is a type of jet engine air intake used by some modern combat aircraft to control air flow into their engines. It consists of a "bump" and a forward-swept inlet cowl, which work together to divert boundary layer airflow away from the ...
BMW — DISA (DIfferenzierte SaugAnlage – "Differential Air Intake"), two stage: M42, M44, M54, N62TU, three stage: N52; DIVA (continuously variable length runners): N62, is the world's first continuously variable length intake manifold. [2] Citroën — XM 3,0 V6.24 (200 hp) used during 1991 to 1997, ZX Coupe 2.0 16v XU10J4 engine.
An intake ramp is a rectangular, plate-like device within the air intake of a jet engine, designed to generate a number of shock waves to aid the inlet compression process at supersonic speeds. [1] The ramp sits at an acute angle to deflect the intake air from the longitudinal direction. [ 2 ]
The set point of the tumble flap is adjusted by an electrical or vacuum-activated servo mechanism which is under the control of the engine management system.Tumble flaps are open or closed depending on engine operating states (related to engine speed and load), engine temperatures, combustion modes (characterized by air-fuel ratio), catalytic converter heating or cold start active or inactive etc.
The air intake (inlet U.S. [6]) is an aerodynamic duct extending from an entry lip to the engine fan/compressor. For supersonic intakes with variable geometry it is called an intake system, referring to the need for shock-wave and internal duct flow management using variable position surfaces (ramps or cones) and bypass doors.

The ACIS/TVIS System. Acoustic Control Induction System, or ACIS, is an implementation of a variable-length intake manifold system designed by Toyota.. Simply put, the ACIS system uses a single intake air control valve located in the intake to vary the length of the intake tract in order to optimize power and torque, as well as provide better fuel efficiency and reduce intake "roar".

VCT on the intake camshaft is used primarily for increasing engine power and torque as the PCM is able to optimize the opening of the intake valves to match the engine conditions. [ 2 ] VCT is used in Ford's Triton 5.4L 3-valve V8 engine, the Australian Barra 182 and 240 Inline-6s , and Ford's 4.6L 3-valve V8 engine used in the 2006-2010 Ford ...
