The invention discloses a cylinder liner-piston ring test platform for simulating the environment of an LNG fuel diesel engine, comprising a test platform, a sample chamber, a cylinder liner fixture, a piston ring fixture, a main connecting rod, a driving device, a data monitoring device and data acquisition device; the sample chamber is equipped with a compressed air supply device to control the humidity inside; the cylinder liner fixture is set on the test platform in the sample chamber, the bottom of the cylinder liner fixture is equipped with a temperature control device, and the piston ring fixture is set on the cylinder liner in the sample chamber Above the fixture, it is installed on one end of the main connecting rod through a vertical translation device; the middle part of the main connecting rod is connected with the side plate of the sample chamber through a horizontal sliding pair, and extends out of the sample chamber through the transmission device and the driving device; the data monitoring device It is used to monitor the temperature, pressure, friction force and oil film thickness during the relative movement of piston ring and cylinder liner. Real friction conditions such as high temperature, high pressure and dry environment of LNG fueled diesel engine can be simulated.
Description
technical field [0001] The invention belongs to the field of engines, and relates to a cylinder liner-piston ring reciprocating test platform, in particular to a cylinder liner-piston ring test platform for simulating the environment of an LNG fuel diesel engine, which can simulate the high temperature, high pressure and dry environment of an LNG fuel diesel engine. Background technique [0002] Environmental problems have always been a major problem facing human society. Since the beginning of the 21st century, as the consumption of fossil fuels has greatly increased, the emission of greenhouse gases has endangered the safety of human society. Environmental problems have gradually become a constraint on my country's overall sustainable development an important factor. Among them, due to the widespread use of internal combustion engines, energy shortage and environmental pollution have gradually become the primary issues in the environmental problems facing the world today. ...
