Abstract
Official abstract text for this publication.
An engine with a supercharger includes a low pressure loop EGR apparatus. An EGR passage having an inlet connected to an exhaust passage downstream of a turbine and an outlet connected to an intake passage upstream of a compressor. An intake bypass passage is provided to bypass the intake passage downstream of the compressor and the intake passage upstream of the compressor, with an ABV in the intake bypass passage. A throttle valve is closed during stop or deceleration operation of the engine. An electronic control unit (ECU) is configured such that, when the ECU determines based on an operation state of the engine that the EGR valve is in a valve-opened state and the engine is in deceleration operation from a supercharging region, the ECU controls an EGR valve to close and the ABV to open from a valve-closed state delayed from start of closing the EGR valve.
First claim
Opening claim text (preview).
What is claimed is: 1. A control device of an engine with a supercharger, the engine including: the supercharger provided between an intake passage and an exhaust passage of the engine and configured to increase intake pressure in the intake passage, the supercharger including a compressor placed in the intake passage, a turbine placed in the exhaust passage, and a rotary shaft connecting the compressor and the turbine so that the compressor and the turbine are integrally rotata…
