The ship's main engine can be divided into steam engines, internal combustion engines, nuclear power engines, and electric motors according to the nature of the fuel used, the place of combustion, the working fluid used, and its working mode. At present, most ships use reciprocating diesel engines in internal combustion engines as main engines, and some warships use nuclear power engines and electric main engines. Power equipment set up to ensure the normal operation of the ship. The ship's main engine consists of three main parts: ① Main power unit; ② Auxiliary power unit; ③ Other auxiliary machines and equipment.

[0003] Generally, ships are equipped with a fuel injector (hereinafter referred to as fuel head) test room, which is specially used for testing the effectiveness of fuel injectors on the cylinder heads of ship main engines and generators. During the test, there are many fuel injectors, and there is still some residual oil on each fuel injector after the fuel injection test. If it is randomly piled up, it will not only cause oil pollution, but also make the fuel head that has been tested be contaminated again, affecting the use effect.
