気装置。The supercharging passage includes a main intake passage, a supercharging passage with a supercharger interposed therebetween, and a secondary air supply passage branching from the supercharging passage downstream of the supercharger and supplying secondary air to the exhaust system. This system detects engine abnormalities in a supercharged engine that is equipped with a switching valve at the branch between the passage and the secondary air supply passage to introduce the turbocharger as secondary air into the exhaust system during light load operation. An intake system for a supercharged engine, characterized in that a switching valve side control device is provided to switch the switching valve, and the supercharging passage is communicated with a secondary air supply passage when the engine is abnormal.
