Title: Maximum filling efficiency estimation method and apparatus for internal combustion engine
Inventor: SUZUKI KENJI
IPC: F02D43/00
Filed: 2022-03-28
Abstract: To accurately estimate a maximum filling efficiency obtainable under a present engine revolution speed, considering an intake air density influencing a turbocharger.SOLUTION: An internal combustion engine has a turbocharger. A maximum filling efficiency obtainable under a present engine revolution speed for engine torque control is calculated on the basis of the engine revolution speed and a maximum intake air density. The maximum intake air density is obtained from a table defining a relationship between the engine revolution speed and maximum filling efficiency for every intake air density. In a characteristic L1 of a standard intake air density, an increase rate of the maximum filling efficiency increases at a point P1 corresponding to a turbo intercept revolution speed N1. In a low intake air density, the turbo intercept revolution speed changes to a high revolution speed side, that is, toward N2, hence, in a maximum filling efficiency characteristic L2, an increase rate increasingly changes at a point P2. Therefore, an estimation accuracy is better than a characteristic L3 that does not take a change in the intercept revolution speed into consideration.SELECTED DRAWING: Figure 6
