Abstract

An engine system is provided, including an engine, a circulation system that circulates coolant through a water jacket, and a controller. The circulation system includes a radiator passage including a heat exchanger, a bypass passage, a flow rate control device, and a thermally-actuated valve. The engine has a spark plug that forcibly ignites an air-fuel mixture. The engine switches between a first combustion in which the air-fuel mixture combusts without the forcible ignition, and a second combustion in which the air-fuel mixture combusts by the forcible ignition. The controller is electrically connected to the flow rate control device, and when the engine performs the first combustion, the controller controls the flow rate control device to adjust the flow rate of the coolant flowing through the water jacket according to the engine load, by closing the radiator passage and adjusting the flow rate of the coolant flowing through the bypass passage.
