Problems solved by technology
[0002] In the prior art, the compression ratio measurement system of the diesel cetane number measuring machine adopts manual reading of the scale, and its accuracy and stability are greatly affected by human interference. The test reading and test results need to be calculated manually, which cannot be automated, and in the actual use It requires operators to have rich experience, and it is also difficult for maintenance and repair.
Therefore, it takes a long time for the diesel cetane number measuring machine with this structure compression ratio measurement system to reach the required working conditions, and the workload is heavy, which also affects the stability of the machine and the accuracy of measuring samples.

The invention discloses a compression ratio measuring system applied to a diesel cetane number measuring machine. The eccentric position on the opposite side is provided with a nozzle installation hole with a cooling water jacket, which is communicated with the pre-combustion chamber; the fixed part is arranged outside the pre-combustion chamber and is connected with the cylinder head; the rotating part is arranged in the fixed part and is connected to the cylinder head. The contact and positioning connection with the fixed part is used to realize rotation; the lateral moving part is arranged in the inner cavity of the pre-combustion chamber, the rotating part and the fixed part, and is connected with the rotating part to realize the rotation of the rotating part. When rotating, it moves laterally, and the lateral moving part includes a compression ratio plug; a locking part is arranged in the inner cavity of the rotating part and the lateral moving part, and is used to realize the compression ratio plug in the pre-combustion chamber. seal.
Description
technical field [0001] The invention relates to a measuring system, in particular to a compression ratio measuring system applied to a diesel cetane number measuring machine. Background technique [0002] In the prior art, the compression ratio measurement system of the diesel cetane number measuring machine adopts the manual reading of the scale, and its accuracy and stability are greatly affected by human interference. It requires operators to have rich experience, and it is also difficult for maintenance and repairs. Therefore, the diesel cetane number measuring machine with this structure compression ratio measurement system will take a long time for the machine to reach the required working conditions, and the workload will be large, which will affect the stability of the machine and the accuracy of the measured sample. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a compression ratio measurement system applied to a diesel cetan...
