Problems solved by technology

[0017] However, when the operation is carried out using a turbocharger, a supercharger, and LP-EGR having individual operating characteristics, it is difficult to achieve optimal control capable of improving the synergistic effect of these devices, and equipped with a supercharger and a The configuration of the engine system of LP-EGR will inevitably become complicated
[0018] The complex engine system significantly limits the layout of the engine compartment, making it extremely difficult to use the turbocharger, supercharger and LP-EGR at the same time

Abstract

The present invention discloses an engine system based on a turbo charger and a fuel ratio improving method thereof. The engine system may include an electric or mechanical supercharger and an LP-EGR, basically with a turbocharger, an EGR valve, a channel control valve, and a bypass valve, which control the flow rate of external air and exhaust gas, may be integrally operated, and a operation section may be divided into a turbo-lag and low torque section, a mid-load section, and mid / high-load section such that the open amount of EGR valve, channel control valve, and bypass valve may be optimally controlled, such that it may be possible to improve availability for a low-speed / high-load section with turbo-lag reduced, using supercharger and considerably increase the ratio of fuel efficiency improvement in the low-speed / high-load section, using LP-EGR operating with supercharger.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0043833 filed on May 11, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a kind of engine system based on turbocharger (turbocharger), more particularly, the present invention relates to a kind of engine system based on turbocharger and a kind of using this engine system based on turbocharger to improve fuel Efficiency-based approach, this turbocharger-based engine system optimizes the synergy of multiple discrete devices used to enhance engine performance by combining the functions of these devices without detracting from the engine compartment layout. Background technique [0004] Generally, vehicles are equipped with various devices for improving engine performance and fuel efficiency. [0005] A turbocharger, which is a typical device, contr...
