Abstract
An internal combustion engine to which a controller is applied includes a cylinder, a turbocharger, an intake passage, a throttle valve, and an exhaust passage. The turbocharger includes a turbine wheel, a compressor wheel, and a wastegate valve. The controller executes a loss estimating process that calculates an estimated value of a pumping loss of the internal combustion engine from an intake air pressure, which is air pressure at a downstream side of the throttle valve in the intake passage, an engine speed of the internal combustion engine, and a charging pressure.
