Abstract: A method of manufacturing an internal combustion engine is provided. The engine includes a cylinder forming member, a piston reciprocatably accommodated in a cylinder, an injector which supplies fuel into a combustion chamber, and a heat insulating layer covering at least a part of a combustion-chamber wall surface and having a lower heat conductivity than the combustion-chamber wall surface. The method includes applying a coating material that is a material of the heat insulating layer to the combustion-chamber wall surface, assembling the piston to the cylinder forming member while the coating material is uncured, and heating the coating material to be cured by combusting the fuel injected from the injector and reciprocating the piston. The heating the coating material includes injecting the fuel from the injector at least in an early stage of the heating so that the injected fuel adhering to the surface of the coating material is suppressed.

Abstract: A device includes a battery case (42) that stores a battery (62A or 62B), a lock mechanism (133) that is capable of fixing and holding the stored battery (62A or 62B) in the battery case (42), and an operation member (44) that is capable of performing switching operation of the lock mechanism (133) between a battery-fixed state and a non-battery-fixed state.
