Abstract
Herein disclosed is an exhaust gas recirculation system for an internal combustion engine, in which system communication is provided between an exhaust passage and an intake passage by way of an exhaust gas recirculation passage so that the exhaust gas in the exhaust passage is partially recirculated into the intake passage by the intake vacuum prevailing in the intake passage. The exhaust gas recirculation system is constructed to include: a vacuum-operated type exhaust gas recirculation valve disposed midway of the exhaust gas recirculation passage for regulating and controlling the flow rate of the exhaust gas to flow in said exhaust gas recirculation passage; a vacuum supply passage for providing communication of a vacuum chamber of the exhaust gas recirculation valve with the intake passage downstream of a throttle valve; a vacuum control valve connected with the vacuum supply passage for controlling the vacuum force of intake air to flow in the vacuum supply passage; and an interlocking mechanism for interlocking the vacuum control valve and the throttle valve. As a result, the exhaust gas recirculation control can be properly conducted, and a rider is enabled to do his throttling operation smoothly and lightly.
