INTERNAL COMBUSTION ENGINE TURBOSUPERCHARGE CONTROL DEVICE Russian patent published in 2017 - IPC F02B37/12 F01N3/04 F02D23/02 

FIELD: engines and pumps.

SUBSTANCE: device comprises a turbocharger (1) with a turbine (2), which input is connected to output manifold (6) of the engine, and a compressor (3), which output is connected through a cooler 4 and a throttle valve 5 to the input manifold (6), a catalyst (9), which input is connected to turbine output (2), a control unit (10), controllable liquid injection module (16) installed in engine output branch pipe (17) before the turbine input (2), and a supercharging controller (19) connected to information bus (20) control unit (10). The information inputs of the unit (10) are electrically connected to temperature and pressure sensors (11) installed at compressor input (3), at the throttle damper (5) input, at the input manifold (6), at a block of cylinders (12) and output manifold (13) of internal combustion engine, as well as with exhaust gases emission control sensors (14) installed at the input and output of catalyst (9). The control input of the unit (10) is connected to accelerator sensor (15), and its control output is connected to the throttle damper (5). The information inputs of pressurisation controller (19) are connected to temperature and pressure sensors (11) installed at the input of the throttle damper (5), the engine output manifold (6), and at input and output of the turbine (2). The control output of the controller (19) is connected to the control input of controlled liquid injection module (16).

EFFECT: improved engine control dynamics and reduced toxicity.
