Starting method and starting device of internal combustion engine, method and device of estimating starting energy employed for starting method and starting device

摘要

A method of starting an internal combustion engine is characterized by comprising: setting a target kinetic energy as being a kinetic energy required for starting the internal combustion engine; and supplying a starting energy controlled in accordance with the target kinetic energy to the internal combustion engine from a predetermined starting energy supply source, wherein the starting energy supply source includes a primary energy supply source and a secondary energy supply source, a difference between the target kinetic energy and a kinetic energy supplied from the primary energy supply source is obtained, and a kinetic energy corresponding to the obtained difference is further supplied from the secondary energy supply source, wherein the primary energy supply source supplies the kinetic energy generated by a combustion within a cylinder (2) of the internal combustion engine.
