Title:
MULTI-CYLINDER ENGINE
Document Type and Number:
Japanese Patent JP2013194682
Kind Code:
A
Abstract:

To suppress variations in explosion forces among a plurality of cylinders and to bring an explosion force of each cylinder to a predetermined target value as close as possible in a multi-cylinder engine including an engine body having a plurality of cylinders, a supercharger, and a plurality of fuel injection devices for supplying fuel to each of the plurality of cylinders.

A deviation between a reference turbocharger rotational speed determined based on an engine speed and an engine load and a turbocharger rotational speed for each explosion stroke of each cylinder is obtained, a reference fuel injection amount to each of a plurality of cylinders calculated based on the engine speed and the engine load using a correction value depending on the turbocharger rotational speed deviation is corrected, and a corrected fuel injection amount that should be supplied for each cylinder is calculated.
