Title:
DEVICE FOR CONTROLLING AMOUNT OF FLUID FED TO INTAKE OF SUPERCHARGED INTERNAL-COMBUSTION ENGINE EQUIPPED WITH EXHAUST GAS RECIRCULATION CIRCUIT AND METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2018135884
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a boost circuit and an EGR circuit to be used within a single engine while preventing a risk of collision between the two circuits and preventing their respective lines and controllers from becoming excessively complicated.SOLUTION: The device according to the present invention is a device for controlling the amount of fluid fed to the intake of a supercharged internal-combustion engine, the supercharged internal-combustion engine comprising: a turbocharger with a compression part including a compressor having an intake for the fluid to be compressed and connected to a delivery line, and with an expansion part including a turbine having an exhaust gas inlet and an expanded exhaust gas outlet and connected to an expanded exhaust gas line; a transfer line carrying the compressed fluid from the compressor outlet to the turbine inlet and comprising throttling means for controlling the compressed fluid transfer to the turbine; and an exhaust gas recirculation line between the exhaust gas outlet of the turbine and the intake of the compressor.SELECTED DRAWING: Figure 1
