ENGINE AND METHOD FOR CONTROLLING ENGINE

WIPO Patent Application WO/2018/051748

A1

Provided are an engine and a method for controlling an engine, with which an engine body can be operated in a stable manner. This engine is provided with an engine body, an engine control device that controls the actions of the engine body, and an EGR system that recirculates some of the exhaust gas expelled from the engine body as recirculated gas to the engine body. The EGR system is provided with an exhaust gas recirculation line that recirculates some of the exhaust gas expelled from the engine body as recirculated gas to the engine body, an EGR control device that controls the recirculated gas supplied to the engine via the exhaust gas recirculation line and transmits and receives information to and from the engine control device, and a transfer coefficient calculation device that outputs information about a transfer coefficient that increases as time elapses. When the supply of exhaust gas from the exhaust gas recirculation line to the engine body is initiated, the transfer coefficient calculation device initiates the increase in the transfer coefficient and transmits the information about the transfer coefficient to the EGR control device and the engine control device.
