CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

Title:

CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2013/014739

Kind Code:

A1

Abstract:

A particulate matter sensor (8), which emits output according to the quantity of particulate matter in gas, is installed on an exhaust path (4) of an internal combustion engine (2). A control device (10) is provided with a means for detecting the output of the particulate matter sensor (8), a means for detecting information pertaining to the operating condition of the internal combustion engine (2), and a means for correcting the output according to the information in a predetermined period from when the internal combustion engine starts to when the engine warms up. By correcting the output when such an internal combustion engine starts, variations in the output of the particulate matter sensor (8), which occur due to differences in particle diameters and sensor temperatures, are minimized.
