Abstract
A particulate detection system () detects the quantity of particulates S contained in exhaust gas EG discharged from an internal combustion engine ENG and flowing through an exhaust pipe EP. The system () includes a detection section () attached to the exhaust pipe EP; and a drive processing circuit () electrically connected to the detection section (), driving the detection section (), and detecting and processing a signal Is from the detection section. The drive processing circuit () includes drive start delay means (S, S, S, S, S, S, S) for delaying start of the drive of the detection section () until a start condition determined by the drive processing circuit () is satisfied after startup of the internal combustion engine ENG.
