Embodiment Construction

[0021] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0022] The automobile engine has a cylinder block 2 with several cylinders 1 and a number of pistons 3 consistent with the number of cylinders 1, and each piston 3 is located at a corresponding cylinder 1, such as figure 1 As shown, the number of cylinder 1 and piston 3 in this embodiment is four, figure 1 In order to show that there is a lubricating gap between the piston 3 and the cylinder 1, the lubricating gap is enlarged, and the actual lubricating gap between the piston 3 and the cylinder 1 is relatively small.

[0023] Such as figure 1 Shown, this automobile engine piston 3 lubricating effect observation device comprises the frame 4 that is used to place cylinder block 2 and is positioned at the machine oil sump 5 ...

Abstract

The invention provides a lubrication effect observing device for engine pistons of an automobile and belongs to the technical field of automobile manufacture, and the device is used for solving the problem that the existing lubrication effect of the engine pistons of the automobile cannot be observed. The lubrication effect observing device for the engine pistons of the automobile disclosed by the invention comprises a rack for placing an air cylinder body and an engine oil pool which is arranged below the rack and is used for containing engine oil. The inner end of one oil pipe is located in the engine oil pool and the outer end of the oil pipe extends out to the air cylinder body. The outer end of the oil pipe is fixedly connected with oil nozzles which are the same with the pistons in quantity. Each oil nozzle points to the corresponding piston. The oil pipe is connected with an engine pump and the engine pump is linked with a control structure for controlling the flow of the engine oil pump. The lubrication effect observing device disclosed by the invention further comprises an observing piece which can be used for observing by extending into an air cylinder and is connected with a display screen. The observing piece is linked with the control structure. The lubrication effect observing device disclosed by the invention has the advantages of direct observation and easiness for implementation.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to an automobile engine observation device, in particular to an automobile engine piston lubrication effect observation device. Background technique [0002] When the car is running, the piston of the car engine is in high-speed reciprocating motion, that is, there is a rapid relative sliding between the piston and the cylinder of the car engine. In order to prevent the parts from wearing out too quickly, it is necessary to establish an oil film between the piston and the cylinder. The surfaces of the piston and cylinder are separated to reduce wear. Therefore, the quality of the lubricating effect at the engine piston determines whether the engine performance can be effectively brought into play to a large extent, so existing automobiles are all provided with an oil supply structure that sprays engine oil toward the engine piston. [0003] The current oil supply str...
