DEVICE TO CONTROL TURBOCHARGED INTERNAL COMBUSTION ENGINE Russian patent published in 2017 - IPC F02B37/10 F02G5/02 

FIELD: engines and pumps.

SUBSTANCE: device comprises a turbocharger (1) with a turbine (2) and a compressor (3), which outlet is connected through a cooler (4), and a throttle valve 5 with inlet manifold (6) of the engine, a catalyst (9) installed after the turbine (2) and before heat exchanger (10), a steam turbine (15), which inlet communicates with the outlet of the heat exchanger (10), and an outlet connected to capacitor input (16), which output is connected to reservoir input (18), a pump (19) connected between the reservoir (18) and heat exchanger (10). The device also includes a separator (20) connected to the outlet of the heat exchanger (10) and which condensate outlet is connected to the reservoir (18), and steam outlet connected through a check valve (21) to steam accumulator (22), which first outlet is communicated with steam turbine inlet (15) through adjustable steam damper (23), and a second output connected through check valve (17) to the capacitor input (16). The steam turbine (15) is arranged on a common shaft with turbosupercharger (1). To control the turbocharge, the device includes in a combined information line (26) a control unit (11) and controller (25) of steam turbine control which receives information signals from throttle sensor (27), temperature and pressure sensors (12, 28), on the basis of which the control signals delivered to throttle valve (5), controlled steam damper (23) and the pump (15) are generated.

EFFECT: efficiency and engine intake are improved.
