KNOWN STATE OF THE TECHNIQUE Two-stroke and four-stroke internal combustion engines for vehicles, ships, electricity generation It is used in many areas, especially generators in power plants. Briefly two and four If we define stroke engines; four-stroke engines, one cycle of the piston in four stages (4-stroke cycle) are the engine types that are completed. Two-stroke engine more commonly The difference from the four-stroke engine used is in the linear movements of the piston, two instead of four. having a stroke. But in these two strokes, the four operations of the four-stroke engine (suction, compression, combustion, exhaust). So sucking and banging a combustion and exhaust are done in one stroke.

Today, especially in ships that cycle with fossil heavy fuels such as diesel and fuel oil, the main propulsion mechanism and used in generators in power generation plants. in engines/machines; great work-production loss, very high repair, spare parts, time and labor Valve failure, which causes costs, is a frequently encountered malfunction. Fossil fuel is the cause of the majority of valve cut-off failures in the current art. valve and valve guide/jacket of post-combustion residues over time due to poor quality formation of soot and deposits on the lower part, cold or hot corrosion, cavitation formation, again due to the poor quality and pollution of the lubricating oil on the upper part of the valve and valve guide. It is sedimentation and deposit that occurs over time.

Failure of the valves to break or cut due to the reasons explained above. First, there is a slowdown in the valve's rotation speed, an increase in its temperature and a decrease in its vertical movement. synchronization error occurs. However, it is possible to detect them in the current technique. is not.
