Abstract
Disclosed is a method for detecting disconnection of a closed breatherseparating and recovering oil mist from blow-by gasextracted from an engineto return the blow-by gas through a gas return pipeto an intake pipe. Under condition of no exhaust gasrecirculation being conducted, a mass flow rate of in-cylinder working gas is calculated based on a boost pressure, an intake temperature of an intake manifoldand a rotational frequency of the engine, and whether the calculated mass flow rate is divergent from a value detected by an air flow sensoris determined. When determined to be divergent, the divergence in a last determination is compared with a current divergence; if difference between the divergences is beyond a predetermined range, the gas return pipeis determined to be in disconnection from the intake pipe
