V-TYPE SUPERCHARGED INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: each set of the cylinders of the engine is provided with a turbine compressor with a system for cooling of supercharging air that comprises path for supercharging air composed of inlet manifold, supplying and discharging pipe lines, and two-compartment cooler of supercharging air whose compartments are interconnected through a common manifold. The inlet and outlet of the cooler are connected with the turbine compressor and inlet pipe line of the engine, respectively. The compartment of the cooler are interconnected with a common receiving manifold and have individual separating manifolds each of which is connected with the turbine compressor of respective cylinder set. From the side of supercharging air the heat exchanging surface of the cooler has turbulizers made up as perforations in the ribs on the heat exchanging surface. Each of the turbine compressors is connected with its inlet manifolds through a by-passing valve. EFFECT: enhanced efficiency. 3 cl, 2 dwg
