Engine provided with turbo-supercharger

Abstract

Abstract PURPOSE:To enhance the accelerating response of an engine with a simple structure without the necessity of a check valve, by disposing compressors, respectively in two intake-air passages separately opened to a combustion chamber, and also by providing turbines in series in an exhaust passage. CONSTITUTION:First and second branched intake-air passages 18 through 21, 22 through 25 are separately opened to the combustion chambers of cylinders 1 through 4 thorough surge tanks 16, 17. With this arrangement, upon intake- stroke no blow-off of intake-air occures even if they are communicated with each other through the combustion chambers whose pressure becomes negative during intake-stroke. Further, the turbines 26, 27 of first and second turbo-superchargers 10, 10 are disposed in series in an exhaust passage 32, and therefore, the turbines 26, 27 receives all volume of exhaust gas so that they rotate high- responsively.
