Method for determining filling of suction tube with fuel in petrol engine, involves utilizing rotation speed, suction tube pressure and temperature, exhaust gas mass flow, valve timing and valve stroke as inputs of model

摘要

The method involves utilizing rotation speed, suction tube pressure (Ps), suction tube temperature, exhaust gas mass flow, external exhaust gas recirculation of an internal combustion engine, output quantity of a model for internal residual gas determination, a valve timing, a valve stroke and a variable for a course of a mode switching of the engine as model inputs. The variable is selected from running time, cycle number and specification of a switching strategy. The switching is carried-out from an initial mode into an operating mode e.g. spark-ignition mode or a self-igniting mode. The mode is selected from a homogeneous charge compression ignition (HCCI) mode, a controlled auto ignition (CAI) mode, an active thermal atmosphere combustion (ATAC) mode and a Toyota soken (TS) mode. The model is selected from an empirical model and a physically based model. Independent claims are also included for the following: (1) a computer program comprising a set of instructions for performing a method for determining cylinder filling of an internal combustion engine (2) a data carrier comprising a set of instructions for performing a method for determining cylinder filling of an internal combustion engine (3) a control device for operating an internal combustion engine.
