Title:
COMBUSTION SYSTEM CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/090404
Kind Code:
A1
Abstract:
As a combustion system control device, an ECU (80) is equipped with a first estimation unit (81a), a second estimation unit (82a), a comparison-selection unit (83), and various control units such as an injection control unit (85a). On the basis of a detection value from a cylinder sensor (21), which is a combustion sensor, the first estimation unit (81a) estimates, as a first estimated value, the air-fuel ratio for each type of molecular structure included in the fuel. On the basis of detection values from a density sensor (27) and a kinetic viscosity sensor (28), which are property sensors, the second estimation unit (82a) estimates the air-fuel ratios as a second estimated value. The comparison-selection unit (83) compares the first estimated value and the second estimated value, and selects the estimated value having the higher estimation precision. The various control units such as the injection control unit (85a) use the selected estimated value to control the operation of the combustion system.
