METHOD OF CONTROLLING DIESEL WITH TURBO-REJECTION AND DEVICE THEREFOR Russian patent published in 2019 - IPC F02G5/02 F02D23/02 F02D1/14 

FIELD: machine building.

SUBSTANCE: invention may be used in supercharge diesels. Control method of turbo-charged diesel engine consists in that after fuel combustion and expansion in diesel engine cylinder (31) exhaust gases with excessive energy are directed by outlet pipeline (7) for expansion into gas turbine (10). Operation of gas turbine (10) by means of the shaft is transmitted to compressor (12) for compression of the supercharging air supplied to the cylinder of the supercharging air cylinder. Control of diesel engine (31) with turbo-supercharging is performed by closing of feedback along two parameters - speed of crankshaft rotation and pressure of supercharging. Control of rotation speed of shaft (2) of diesel engine (31) is performed by negative feedback. Control of boost pressure is performed by positive feedback by two-pulse controller (30) acting on common control element of fuel supply to cylinder of diesel engine - rail of high pressure fuel pump. Water is fed into outlet pipeline (7) upstream of gas turbine (10). Water supply is controlled by feedback closing by two parameters - crankshaft rotation speed and supercharging pressure. There is disclosed control device for diesel engine with turbocharger.

EFFECT: technical result consists in providing more complete utilization of exhaust gas energy by automatic control of boost pressure in any modes of movement of a power plant using a diesel engine with turbocharged engine.
