Document Type and Number:
WIPO Patent Application WO/2015/146545
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an engine device which can maintain the exhaust gas temperature at a high temperature and can burn away particulate matter when regenerating an exhaust gas purification device. This work vehicle is provided with an engine (5), an exhaust gas purification device (50) arranged in the exhaust path of the engine (5), and an engine control device (311) which controls driving of the engine (5). The engine control device (311) performs multiple types of regeneration control for burning away particulate matter that has accumulated in the exhaust gas purification device (50). In non-work regeneration control, which is one of the multiple types of regeneration control, the engine control device (311) drives the engine (5) exclusively for burning away particulate matter, and forcibly performs isochronous control in order to maintain the rotation speed of the engine (5) constant regardless of fluctuation in the load on the engine (5).
