A nonlinear model for a single-cylinder diesel engine is developed in the angle domain. The model can be used as an engine simulator to aid diesel engines control system design and fault diagnostics. The model does not use any empirical inputs, and accurately predicts in-cycle variations of engine parameters during transient response. The model treats the cylinder strokes and the manifolds as thermodynamic control volumes by using the filling and emptying method, solving energy and mass conservation equations with submodels for combustion, heat transfer, instantaneous friction and dynamic analysis. Inertia variations and piston pin offset are taken into consideration. In-cycle calculations are performed at each crank-angle, so the correct crank-angle of ignition, speed variation, amount of fuel and air as well as the fuel burning rate are predicted. The model is validated using experimentally measured cylinder pressure and engine instantaneous speeds, under transient operating conditions, giving good agreement.
