AI Technical Summary
Existing technologies cannot effectively maintain valve clearance in the valve train of high-speed diesel engines, leading to valve leakage and wear, which affects the performance and reliability of diesel engines.
The wear of the valve and valve seat is measured by material-level testing. Valve caps and guide tubes with different hardness are selected to ensure that the wear is similar and the valve clearance is kept within a reasonable range. The valve cap hardness is increased by quenching treatment to compensate for the wear difference.
This achieves stability of valve clearance after long-term operation of the diesel engine, reduces malfunctions and wear caused by valve clearance, and improves the reliability and performance of the diesel engine.
