Abstract
An object is to provide a starting diagnosis apparatus for an internal combustion engine system, capable of diagnosing an abnormal location of an internal combustion engine system. The starting diagnosis apparatus includes: a pressure sensorwhich measures a cylinder pressure for each of the cylinders; a starting confirming unitwhich confirms whether the internal combustion engine system fails to start; a cylinder-pressure increase confirming unitwhich confirms an increase of the cylinder pressure for each of the plurality of cylinders, on the basis of a pressure measurement result of the pressure sensor, if the starting confirming unitconfirms a failure; a normal-cylinder confirming unitwhich confirms whether the cylinder for which the increase of the cylinder pressure is confirmed by the cylinder-pressure increase confirming unitis a normal cylinder; and a diagnosing unitwhich diagnoses an abnormal location of the internal combustion engine system on the basis of confirmation results of the cylinder-pressure increase confirming unitand the normal-cylinder confirming unit
