Description
Technical field
The invention belongs to engine art, be specifically related to the lubricated analogue means of a kind of engine piston ring cylinder jacket.
Background technology
Under the situation that the energy and environmental issue are very severe now; Requirement for internal combustion engine is more and more stricter; Add the high speed high load capacity, increase the service life and long-term continuous working etc. that an urgent demand improves the wearing quality of friction pair in the internal combustion engine, reduces because the power that rubs and lose.
Research shows; The friction power loss that internal combustion engine is caused by reciprocating type friction pair piston ring-cylinder jacket in the course of the work can account for 65% of whole engine friction power consumption when maximum, and its friction, wearing and tearing and greasy property directly influence the power consumption, exhaust emissions of engine etc.Therefore, the friction power loss that how to reduce piston ring-cylinder liner is that numerous scholars and engineering technical personnel endeavour the important topic studied all the time.
In recent years, method and the emphasis about piston ring-cylinder jacket friction pair research is a lot of both at home and abroad, but because the complicacy of piston system, a little less than the simulation test research relatively of piston ring-cylinder jacket friction process.For this reason, 70 domestic relevant universities and colleges have developed piston ring-cylinder jacket simulation friction-wear test system jointly.This system can simulate piston ring-cylinder jacket reciprocatingly slide motion, can realize that piston ring loads, also can realize through resistance heated the environment temperature of friction pair to the radially swelling of cylinder jacket; But; Fail to resolve the spray lubrication between piston ring-cylinder jacket always; Cause lubricating oil skewness in the process of the test, more serious eccentric wear phenomenon occurs, bring very big difficulty for the evaluation of later stage friction pair friction and wear characteristic.
Summary of the invention
Technical matters to be solved by this invention provides the lubricated analogue means of a kind of engine piston ring cylinder jacket; This device is used for the spray lubrication state of simulated engine piston ring-cylinder jacket friction pair; Stable and reliable operation, lubricated simulate effect are good, have solved the eccentric wear problem of cylinder liner-piston ring.
Technical scheme of the present invention: a kind of engine piston ring cylinder jacket is lubricated analogue means; It comprises grease-box, timing controller, electronic pump, flow pump, tensimeter, plastic flexible pipe, oil spout copper pipe, annular holder and upper piston; Grease-box is connected with the oil spout copper pipe through plastic flexible pipe; Plastic flexible pipe is connected with timing controller, electronic pump, flow pump, tensimeter, evenly is provided with two above double horn shape spray orifices on the oil spout copper pipe, and the pitch-row of believing two double horn shape spray orifices is 10mm; The axis of double horn spray orifice and the angle of normal are 30 °; Described oil spout copper pipe is arranged in the annular groove of annular holder, and annular holder is connected with upper piston, and the cross sectional shape of annular holder and upper piston joint face is conical.
The present invention compared with prior art has following beneficial effect: lubricating oil extracts from fuel tank through the electronics oil pump; Fuel delivery and supply time are regulated through timing controller; Charge oil pressure 0.2MPa; Lubricating oil is under pressure from the ejection of double horn shape jet, with simulated engine piston ring-cylinder jacket spray lubrication.Have the advantages that controllability is strong, simulate effect is remarkable, cost is low, except that can simulating friction pair lubricated, can also be generalized to the acid etching effect of simulation friction pair, solved the eccentric wear problem of cylinder liner-piston ring.
