Title:
CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE AND CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/203361
Kind Code:
A1
Abstract:
According to the present invention, an internal combustion engine (1): can modify a mechanical compression ratio by modifying the range in which a piston (33) slides along a cylinder bore (32); and can control the flow of cooling water inside a water jacket (31a) that is provided around the cylinder bore (32). When a cooling water temperature (Tw) at the water jacket (31a), which correlates with a cylinder bore wall temperature, is below a prescribed temperature (Twth), the flow of cooling water inside the water jacket (31a) is suspended, which rapidly increases the cylinder bore wall temperature and rapidly stops the condensation of water on an inner circumferential surface (32a) of the cylinder bore (32), making it possible to delay the progress of corrosion of the inner circumferential surface (32a) of the cylinder bore (32).
