Abstract
A kind of car engine ignition advance angle teaching aid, including supporting table, engine, transmission shaft, pointer, instruction disk, engine is placed in instruction disk in supporting table, and transmission shaft passes through instruction disk to be connected with one end of engine crankshaft；Pointer is fixed on transmission shaft, is intersected vertically with the central axes of transmission shaft.The rotary motion of engine crankshaft is converted to the rotation for being fixed on pointer in connecting shaft by using the mode of connecting shaft by the utility model, again by indicating that disk is identified the angle that it is rotated, so that the motion process of engine crankshaft is very clear, the other end of engine is operated manually by manual axle mechanism, facilitate the motion process of control engine crankshaft, the motion state of bent axle can be adjusted in time with the explanation of teacher, make student clearer in teaching process, the apparent concept for understanding engine advanced ignition angle, and student is made to have more intuitive understanding to the motion process of engine, convenient for the development of re-service term.
Description
Technical field
The utility model is related to a kind of car engine ignition advance angle teaching aids.
Background technology
The mixed gas of petrol engine is in burning, from lighting, being burned to burning-out there are one time course, from during igniting
It plays piston quarter and reaches compression top center, the angle that this period, inside crankshaft turned over is known as ignition advance angle, and optimum igniting shifts to an earlier date
Angle is exactly that gas expansion trend largest segment is made to be in piston acting descending stroke under various different operating modes.Efficiency highest in this way,
Vibration is minimum, and temperature rises minimum.When being imparted knowledge to students, due to being related to specific internal structure, need to transport bent axle in teaching
Dynamic process and corresponding advanced ignition angle are presented, and are otherwise difficult that student is allowed to fully understand this concept.And it teaches at present
Method used by class hour is mostly explained using the schematic diagram of structure of engine, and process is complicated, student's indigestion.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of car engine ignition advance angle teaching aid.
The utility model is achieved by the following technical programs.
A kind of car engine ignition advance angle teaching aid provided by the utility model, it is characterised in that：Including supporting table, hair
Motivation, transmission shaft, pointer, instruction disk, engine are placed in instruction disk in supporting table, and transmission shaft passes through instruction disk bent with engine
One end of axis is connected；Pointer is fixed on transmission shaft, is intersected vertically with the central axes of transmission shaft.
Also a manual wheel shaft is connected with the other end of engine crankshaft.
Transmission shaft passes through the center of circle of instruction disk, and the central shaft of transmission shaft is with indicating that the center of circle of disk overlaps.
The length of pointer is between the radius and diameter of instruction disk.
Angle index is labeled on the instruction disk, shown scale is with vertically upward for 0 degree.
The engine is in-line engine.
The beneficial effects of the utility model are：The utility model is by using the mode of connecting shaft by engine crankshaft
Rotary motion is converted to the rotation for being fixed on pointer in connecting shaft, then by indicating that disk is identified the angle that it is rotated, makes
The motion process for obtaining engine crankshaft is very clear, and the other end of engine is operated manually by manual axle mechanism, side
Just the motion process of engine crankshaft is controlled, the motion state of bent axle can be adjusted in time with the explanation of teacher, student is allowed to teach
It is clearer, apparent during learning to understand the concept at engine advanced ignition angle, and make motion process of the student to engine
There is more intuitive understanding, convenient for the development of re-service term.
Description of the drawings
Fig. 1 is the left view of the utility model；
Fig. 2 is the front view of the utility model；
In figure：1- supporting tables, 2- engines, the manual wheel shafts of 3-, 4- transmission shafts, 5- pointers, 6- instruction disks.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1 and Figure 2, a kind of car engine ignition advance angle teaching aid including supporting table 1, engine 2, passes
Moving axis 4, pointer 5, instruction disk 6, engine 2 are placed in instruction disk 6 in supporting table 1, and transmission shaft 4 passes through instruction disk 6 and engine 2
One end of bent axle is connected；Pointer 5 is fixed on transmission shaft 4, is intersected vertically with the central axes of transmission shaft 4.
Also a manual wheel shaft 3 is connected with the other end of 2 bent axle of engine.
Transmission shaft 4 passes through the center of circle of instruction disk 6, and the central shaft of transmission shaft 4 is with indicating that the center of circle of disk 6 overlaps.
The length of pointer 5 is between the radius and diameter of instruction disk 6.
Angle index is labeled on the instruction disk 6, shown scale is with vertically upward for 0 degree.
The engine 2 is in-line engine.
As the engine that teaching uses, in order to protrude internal structure, section processing need to be done to it in early period, removes part
Its internal structure is presented in shell.Further, it is also possible to by the various stages that the bent axle of engine 2 is run on instruction disk 6
It is indicated, the operational process of complete engine 2 is showed by the rotation angle of pointer 5.
In use, rotation manual wheel shaft 3, the crank rotation of drive engine 2, at this point, due to being connected with valve on bent axle
The mechanisms such as connecting rod, valve can also be moved together therewith, can simulate corresponding state and process when engine works.By
It is connect in pointer 5 by connecting shaft 4 with the bent axle of engine 2, the rotation synchronized with bent axle, by indicating 6 upper angle of disk
Mark, teacher can combine engine motion process the concept of advance angle of engine ignition is explained.
