Title:
pH REGULATION DEVICE FOR CYLINDER LINER SLIDING SURFACE OF INTERNAL COMBUSTION ENGINE, CYLINDER OILING DEVICE FOR INTERNAL COMBUSTION ENGINE, AND INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/147427
Kind Code:
A1
Abstract:
Provided are a pH regulation device for a cylinder liner sliding surface, a cylinder oiling device for an internal combustion engine, and an internal combustion engine, in which the pH value of a cylinder liner sliding surface can be maintained in an appropriate range irrespective of how much sulfur is contained in fuel. The pH regulation device is provided with a pH detection means (14) for detecting the pH value of the cylinder liner sliding surface of the internal combustion engine, a regulatory agent feeding means for feeding in a pH regulatory agent, a regulatory agent supply channel, a regulatory agent supply rate regulation means (11) for regulating the supply rate of the pH regulatory agent, and a control means (20). The control means (20) is provided with a regulatory agent supply rate setting unit (23) for setting the supply rate of the pH regulatory agent on the basis of the detection result of the pH detection means (14) so that the pH value of the sliding surface is kept within an appropriate range, and a regulatory agent regulation means control unit (24) for controlling the operation of the regulatory agent supply rate regulation means (11) so that the pH regulatory agent can be supplied to the sliding surface at the supply rate set by the regulatory agent supply rate setting unit (23).
