Abstract

See full text

An engine of the invention includes an engine main unit having cylinders, an intake line, an exhaust line, a supercharger, a turbo sensor detecting a rotational speed of the supercharger, a control device controlling, based on signal from the turbo sensor, an operating state of the engine main unit that has a correlation with the rotational speed of the supercharger, and a crank angle sensor detecting a rotation angle of a crankshaft. The control device recognizes timings at which the cylinders are in a top dead center state based on detection signals of the crank angle sensor and, also, makes a disconnection judgment for the turbo sensor at non-top dead center timings that are within one combustion cycle of the engine main unit and at which none of the plurality of cylinders are in a top dead center state.
