Description

LO

WITH

The invention relates to mechanical engineering, in particular to combined internal combustion engines with adjustable supercharging,

The purpose of the invention is to increase the efficiency of the engine.

The drawing shows a schematic diagram of the engine.

The internal combustion engine 1 is made with an exhaust manifold 2, to which a power turbine 3 is connected successively along the exhaust gas, connected by means of a kinematic transmission 4 to the crankshaft of the engine 1, and the turbine 5 of the turbocompressor 6. The gas inlet pipe of the turbine 5 is connected to the exhaust manifold gases of the power turbine 3 and is connected to the atmosphere by means of a bypass channel 7, equipped with an overlapping body 8, which is connected to the actuator 9 of the drive.

Transmission is performed with a variable gear ratio. The intake pipe 10 of the engine 1, to which the air-inlet port of the turbocharger is connected, communicates through channel 11 with the atmosphere through the inlet pipe of the compressor 12, which is part of the turbocharger 6. In channel 11, the check valve 13 is installed with the possibility of opening inside the inlet pipe the engine load and the sensor 15 of the frequency of rotation of the shaft of the engine 1, which are associated with the block 16 of the control body 8 blocking the bypass channel and the body change (not shown) gear ratio gear 4.

When the engine is operating at loads close to nominal, the exhaust gases are fed through the exhaust manifold 2 to the turbine 5 of the turbocharger 6. where they do work that is spent on compression

air in the compressor 12 and creating the necessary pressure in the intake manifold of the engine 1. Sensors 14 and 15 of the load and rotational speed of the crankshaft of the engine 1 continuously receive signals to the control unit 16. If the energy of exhaust gases in the cylinder exceeds the value required to create the pressure in the intake manifold, then part of the energy is transmitted through the power turbine 3 to the shaft of the engine 1 using the control unit 16 in accordance with the signals of the sensors 14 and 15. When the engine load decreases, variable value, depending on the speed of the engine, in block 16 of the control signal is generated. which, using the actuator 9, opens the shut-off body 8 and the exhaust gases are directed after the power turbine 3 through the channel 7 directly to the atmosphere, a mine of the turbine 5 of the turbo-compressor 6. In this case, a negative pressure occurs in the inlet pipe 10 which leads to the opening of the automatic valve 13 that allows the air charge to be supplied to the engine, min compressor 12, via channel 11. Simultaneously, from the control block 16, a control signal is transmitted to gear 4, changing its gear ratio and increasing In this way, the resistance of the flow section of the power turbine 3. The exhaust gases, expanding in the power turbine, perform work that is transmitted to the shaft of the engine 1 through the transmission 4.

The gear ratio control 4 is controlled as follows. Using signals from engine load sensors 14 and crankshaft speed 15, the control unit uses positive feedback to establish the optimum gear ratio for the transmission 4 at which the engine develops maximum torque at a given speed mode.

The memory of the control unit contains the law of variation of the engine torque to create the necessary adaptability factor. Using signals from sensors 14 and 15, the control unit calculates the deviation from the required torque variation law and, using negative feedback, establishes the appropriate position of the gas distributor 8. to eliminate the deviation of the torque from the calculated one.

The turbocharger is disconnected at partial load modes, information about which is stored in the memory of the control unit according to signals from sensors 14

and 15, if the engine load at this speed limit corresponds to the data embedded in control block 16.

Thus, the engine operation is controlled by a dual contour automatic control system with two adjustable values. The first loop is a continuous control with positive feedback by transfer ratio 4, the second loop is continuously discrete control by the organ 8 with negative feedback. As a result of simultaneous adjustment of the bypass
