  • Patent number: 10876465
    Abstract: An intake-air temperature controlling device is provided, which includes an engine body, an intake passage, a supercharger, a first passage, a second passage, an intake air flow rate adjuster, an intercooler, a pump, and a controller. The controller outputs a control signal to the pump so that coolant is supplied to the intercooler in a first operating range in which the intake air flow rate adjuster at least partially opens the first passage to supply intake air boosted by the supercharger to the engine body, and outputs a control signal to the pump so that the coolant is supplied to the intercooler also in a second operating range in which an engine load is below a given load, and the intake air flow rate adjuster opens the second passage and closes the first passage to supply the intake air to the engine body in a non-boosted state.
