Patent ID: 8146573

Claim:
An EGR device for an engine comprising: an EGR passage connecting an exhaust passage of the engine to an intake passage of the engine; a control valve opened and closed for controlling an opening degree thereof defining a passage area of the EGR passage; a valve casing attached to the engine, wherein apart of the EGR passage is formed in the valve casing, and wherein the control valve is provided in the valve casing so as to open and close the part of the EGR passage; a detecting means for detecting an exhaust gas temperature of the engine; a control means that controls the control valve in correspondence to the exhaust gas temperature detected by the detecting means so as to control the passage area of the EGR passage defined by the opening degree of the control valve; a bypass passage bypassing the control valve; a restrictor restricting a passage area of the bypass passage, wherein, when the exhaust gas temperature detected by the detecting means is not less than a predetermined value, the control means fully closes the control valve so as to recirculate exhaust gas from the exhaust passage to the intake passage via only the bypass passage having the passage area restricted by the restrictor.
