ENGINE WITH CONTROLLED TURBOCHARGER SYSTEM Russian patent published in 2018 - IPC F02B37/24 F02D23/00 

FIELD: engine building.

SUBSTANCE: invention can be used in systems of supercharging of diesel engines. Ship engine (1) is equipped with a controlled turbocharging system with a change in the position of the blades of a guiding nozzle device of the turbine. Engine (1) contains turbochargers (2), (3), air supply systems, gas burners, fuel supply, electronic control system (10). Electronic control system (10) receives information about torque on motor shaft (1), frequency of rotation of crankshaft and turbocharger rotors (2), (3), exhaust gas temperatures in front of the turbines, and actuators (8), (9), which change the position of the blades of the turbine nozzle device. Actuators (8), (9), which change the position of the blades of the turbine nozzle device, are at the same time sensors that display the actual angular position of the blades of the guide nozzles of turbine devices. Signal from actuators (8), (9) enters electronic control system (10) parallel to the signals from engine torque sensors (11)–(17), temperature of exhaust gases, rotational speeds of the crankshaft and rotors of turbochargers. Combination of these signals after processing in control electronic system (10) and comparison with their predetermined values in the form of a working mode matrix provides generation of control electrical signals to actuators (8), (9), realizing the necessary position of the blades of the turbine nozzle device, corresponding to the operating modes of the engine, ensuring the optimal coordination of the hydraulic characteristics of the diesel engine and the compressor part of the engine by changing the rotor speed of the turbochargers.

EFFECT: technical result consists in coordination of the hydraulic characteristics of the diesel engine and the compressor part of the engine by changing the rotor speed of the turbochargers.
