INTERNAL COMBUSTION ENGINE WITH EXHAUST-GAS TURBO SUPERCHARGER AND ACCELERATING METHOD FOR EXHAUST-GAS TURBO SUPERCHARGER FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To perform acceleration of an exhaust gas turbosupercharger particularly at high engine speed, by arranging a nozzle member toward a turbine blade, and connecting to a combustion chamber of at least one cylinder in an internal combustion engine through an accumulator. SOLUTION: An exhaust passage in each cylinder of an internal combustion engine, which is a straight-type four-cylinder engine, is connected to an exhaust gas turbosupercharger through an exhaust gas flow pipe, exhaust gas is loaded in a turbine blade 6 of a turbine part 5, and it is rotated. Here, partly in a plurality of cylinders, a hole 19 is formed so as to open in a combustion chamber 20 by penetrating a wall part of a cylinder head 18, and one end of a pressure flow pipe 21 is connected to this hole 19. The other end of the pressure flow pipe 21 is connected to a nozzle member 22 provided toward the turbine blade 6. When the supercharger is in high rotation, in the case of increasing its acceleration, a control valve 24 is opened, accumulated gas in the pressure flow pipe 21 is injected from the nozzle member 22, and, in this way, the turbine blade 6 is additionally driven.
