Abstract
In an operation of an internal combustion engine for a vehicle in which an operation of the internal combustion engine is stopped by a control of a vehicle operation control device during a vehicle operation, the control determination includes a determination that the internal combustion engine is not stopped when a temperature of the catalyst is not equal to or less than a predetermined threshold value.
Claims13
An operation method of an internal combustion engine for a vehicle including the internal combustion engine and an exhaust gas purification catalyst which is provided in a exhaust system of the internal combustion engine comprising:
- determining whether an operation of the internal combustion engine should be stopped during a vehicle operation;
- detecting a temperature of the catalyst;
- and
- determining not to stop the internal combustion engine when the detected temperature of the catalyst is higher than a predetermined threshold value.
An operation method of an internal combustion engine for a vehicle including the internal combustion engine and an exhaust gas purification catalyst which is provided in a exhaust system of the internal combustion engine comprising:
- determining whether an operation of the internal combustion engine should be stopped during a vehicle operation;
- detecting a temperature of the catalyst;
- and
- not stopping the internal combustion engine when the detected temperature of the catalyst is higher than a predetermined threshold value, even if it is determined that the operation of the internal combustion engine should be stopped.
An operation device of an internal combustion engine comprising:
- a detector that detects a temperature of a catalyst of an exhaust gas purification catalyst which is provided in a exhaust system of the internal combustion engine, and
- a controller that determines whether an operation of the internal combustion engine is automatically stopped during a vehicle operation, and that determines not to stop the internal combustion engine when the temperature of the catalyst which is detected by the detector is higher than a predetermined threshold value.
