METHOD OF TYPICAL DETERMINATION OF FRESH AIR AMOUNT BEING SUPPLIED INTO CYLINDERS OF INTERNAL COMBUSTION ENGINE DURING EXTERNAL RETURN OF COMBUSTION PRODUCTS |
摘要 |
A method for calculating an actual fresh-air mass flowing into a cylinder with the aid of an inlet pipe flow model. The description of the flow model is based on a nonlinear differential equation. The chosen model approach contains modeling of an external exhaust-gas recycling system, variable inlet systems and systems with variable control valves. The model-assisted load detection method can be used in engine control systems based on air mass flow and on inlet pipe pressure. A correction algorithm, in the form of a model control loop allows permanent improvement of accuracy when the model parameters are inexact. That is to say model balancing is provided in steady and unsteady operational states. |
