DEVICE FOR SUPPLYING PLENUM AIR TO PISTON TURBO-CHARGED INTERNAL COMBUSTION ENGINE, AND ITS OPERATING METHOD Russian patent published in 2010 - IPC F02B37/04 F02B33/44 F02D9/02 

FIELD: engines and pumps.

SUBSTANCE: invention refers to the device for supplying plenum air to piston turbo-charged internal combustion engine (ICE) equipped with pneumatic accumulator, and to operating method of such device. Device for supplying plenum gas to piston ICE (2) equipped with turbo-charge includes pipeline section (8) for plenum gas. Pipeline section (8) for plenum gas includes controlled gate valve (60), the first (10) and the second (9) end connections (9). Gate valve (60) is connected to control device (66). Between gate valve (60) and the second end connection (9), connection (42) for compressed air (42) opens to internal discharge cavity (62). Connection (42) is equipped with device (68) for controlling the amount of air. Device (68) has valve (70) controlled through electric input (69). The latter is connected to electronic control unit (38). Control device (66) is brought into action with control device (68) for controlling the amount and/or electric control unit (38). Fully closed position of device (60) corresponds to fully open position of gate valve (68). Outputs (71) of the first and the second pressure sensors (72) are connected to electronic control unit (38). Manometre (73) of the first pressure sensor (71) is located in internal inlet cavity (61). Manometre (73) of the second pressure sensor (72) is located in internal outlet cavity (62). Method of improving dynamic characteristic and characteristic of exhaust of piston ICE of transport vehicle involves detection of signal requiring increase of torque moment, determination of engine characteristics, air pressure in internal inlet (61) and outlet (62) cavities, processing of the received data and measured values in electronic control unit (38). The latter creates control signals of pressurisation valve (70) and gate valve (60). It is possible to control boost air charging and gate valve adaptively to the frequency of acceleration performed by the driver.

EFFECT: development of device and method for air supply to cylinders of ICE, which are adapted for the driving method and payload of transport vehicle.
