Abstract

The invention discloses an engine cylinder bore wear simulation test device, which comprises a base, a motor, a connecting shaft sleeve, and a heating oil tank, wherein an engine tray is arranged at the upper side of the base, and is used for supporting and fixing the whole engine, and a motor fixing bracket is arranged at one end of the base; the motor is fixedly arranged on the motor fixing bracket, and the motor is connected with a PLC controller; the PLC controller is used for controlling the rotating speed and working time of the motor, and the connecting shaft sleeve is connected with the motor and the whole engine; the motor drives the whole engine to work by the connecting shaft sleeve, and the heating oil tank is connected with a lubricating oil path of the whole engine to form acirculating loop; an abrasive is stored in the heating oil tank, and the temperature of the heating oil tank is controlled by the PLC controller. The device can obtain the accurate wear resistance test results by actually simulating the engine cylinder bore and cylinder liner operating conditions.

Description

technical field [0001] The invention relates to the field of engine tests, in particular to an engine cylinder hole wear simulation test device. Background technique [0002] With the continuous upgrading of diesel engines, the wear resistance of main engine parts such as cylinder bores and cylinder liners directly affects the overall quality of the engine. At present, the way to compare and evaluate the wear resistance of engine cylinder bores, cylinder liners and other parts is to take suitable samples from local parts of engine cylinder bores and cylinder liners, process them into samples, and then conduct relevant friction and wear tests. So as to compare and evaluate the pros and cons of wear resistance. [0003] However, the friction and wear test method for sampling key components such as engine cylinder bores and cylinder liners is as follows: process the corresponding samples and install them on the friction and wear testing machine, load the load and set the speed...
