Beschreibung
Zusammenfassung:	In an exhaust gas purification system of an emergency vehicle, a control unit performs a regeneration process when a collection amount of particulate matters exceeds a predetermined amount and, at the same time, when conditions for regeneration are satisfied. The control unit shifts the state of the engine to an engine output limitation state in which an engine output is limited when the regeneration process is not performed for a continuous period and the amount of particulate matters collected by the main filter exceeds a first predetermined amount. The control unit forcibly cancels the engine output limitation state when the emergency vehicle is being dispatched to an emergency and when the state of the engine is the engine output limitation state.
