  • Engine controller for a vehicle including an automatic centrifugal clutch
    Patent number: 6932050
    Abstract: An engine controller for a vehicle having an automatic centrifugal clutch device, includes an engine halt controlling means (ECM) for performing engine halt control. The engine halt controlling means halts the engine with the condition that the engine speed becomes equal to or higher than a first set rotational frequency, which is set to be equal to or lower than the clutch engagement rotational frequency of the automatic centrifugal clutch device.
    Type: Grant
    Filed: April 2, 2004
    Date of Patent: August 23, 2005
    Assignee: Suzuki Motor Corporation
    Inventors: Ken Shibano, Eiichi Iyoda
  • Vehicle-mounted four-cycle engine control device
    Patent number: 6834739
    Abstract: A vehicle-mounted four cycle engine control device which includes an oil pressure detecting sensor that detects a pressure of lubricating oil circulated under pressure in an engine. An oil pressure detecting sensor failure judging system judges whether or not the oil pressure detecting sensor has failed. An engine speed judging system judges whether or not a speed of the engine is equal to or above a predetermined engine speed. A pressure state judging system judges whether or not the lubricating oil pressure detected by the oil pressure detecting sensor continues to be in a state of being lower than a predetermined reference pressure for a predetermined time interval or more.
