Abstract
A fuel supply controlling device includes: an auxiliary chamber fuel supply valve that supplies a gaseous fuel to an auxiliary chamber; a non-return valve between the auxiliary chamber fuel supply valve and the auxiliary chamber, the non-return valve blocking a reverse flow from the auxiliary chamber; a valve state detector that detects an operating state of the non-return valve; a rotation angle detector that detects a rotation angle within an engine cycle; and a controller that determines an operation command value of the auxiliary chamber fuel supply valve. The controller measures an actual operating state of the non-return valve based on signals from the valve state detector and the rotation angle detector in association with the detected rotation angle, and corrects the operation command value of the auxiliary chamber fuel supply valve such that the measured actual operating state is brought close to a target operating state.
