Problems solved by technology
[0002] The cylinder head is the main fixing part of the engine. The injector hole on the cylinder head is divided into direct mounting type and oblique mounting type. The tolerance of the end face of the injector mounting hole to the body joint surface (large face) of the cylinder head seriously affects the combustion process of the diesel engine. Combining the common engine faults that appear in the market every year: incomplete combustion, poor atomization of the injector, high exhaust temperature and other faults, such problems are only solved by replacing the injector during routine maintenance. In addition to quality problems, the protruding length of the injector nozzle is rarely analyzed, and it is difficult to analyze and measure it
[0003] There is no measurement datum above the cylinder head, and the machining depends entirely on the accuracy of the machine tool, so effective measurement values cannot be obtained
It is easy to cause the protruding amount of the fuel injector to be out of tolerance after assembly
