Abstract
A work vehicle includes a diesel engine, a heater to heat a gas to be supplied to a combustion chamber of the diesel engine, and a controller to execute an afterglow routine to cause the heater to operate. The controller is configured or programmed to execute the afterglow routine in response to the diesel engine being started, an elapse of a predetermined stop time since an end of a previous execution of the afterglow routine, and the work vehicle being in a warming-up state.
Claims8
A work vehicle comprising:
- a diesel engine;
- a heater to heat a gas to be supplied to a combustion chamber of the diesel engine;
- a controller to execute an afterglow routine to cause the heater to operate;
- and
- a work device;
- wherein
- the controller is configured or programmed to execute the afterglow routine in response to (i) the diesel engine being started, (ii) an elapse of a predetermined stop time since an end of previous execution of the afterglow routine, and (iii) the work vehicle being in a warming-up state;
- and
- the controller is configured or programmed to determine that the work vehicle is in the warming-up state in response to the work device being stopped.
A work vehicle comprising:
- a diesel engine;
- a heater to heat a gas to be supplied to a combustion chamber of the diesel engine;
- a controller to execute an afterglow routine to cause the heater to operate;
- a travel device;
- a work device;
- and
- a parking brake;
- wherein
- the controller is configured or programmed to execute the afterglow routine in response to (i) the diesel engine being started, (ii) an elapse of a predetermined stop time since an end of previous execution of the afterglow routine, and (iii) the work vehicle being in a warming-up state;
- and
- the controller is configured or programmed to determine that the work vehicle is in the warming-up state in response to (i) the travel device being stopped, (ii) the work device being stopped, and (iii) the parking brake being activated.
