摘 要：正In internal-combustion engines with multi cylinders,fuel is injected into cylinders and exhaust gas is discharged from cylinders serially and *** going through runners,exhaust gas flows into the confluence region of exhaust manifold where oxygen sensor is equipped for the air-fuel ratio measurement of the mixed *** paper aims to present a modeling approach from individual cylinder fuel injection to the output of the *** consideration of above features of the exhaust system,a BDC-scaled periodic model is *** further illustration,some previous models are compared with new model. Simulation shows that the new model describes appropriately the relation between individual fuel injection and mixed air-fuel ratio.
