valve-tappet clearance

The causes of phase variation in air supply obtained after analysis are mainly errors in manufacture, abuse in operation and errors in repair. Several adjusting methods for correct installation of timing gears, inspection of meshing clearance of gear faces and adjustment of valve clearance are suggested.

分析了配气相位变化的原因主要是制造误差、使用不当和修配误差等，提出了正确安装正时齿轮、检查齿面啮合间隙和调整气门脚间隙等几种调整方法。

Study on Valve Timing and Fast Adjustment of Valve Clearance of Four-Stroke Internal Combustion Engines

四冲程内燃机配气相位与快速调整气门间隙的研讨

The effects of five adjusting parameters of valve timing, admission valve clearance, emission valve clearance, rotational speed, load rate are interacted.

配气相位、进气门间隙、排气门间隙、转速、负荷五个调整参数之间是相互影响的。

Too much valve clearance causes a lag in valve timing causing engine valve train imbalance.

气门间隙过大会引起气门调时延迟,造成引擎气门组系不平衡.

Furthermore, this thesis also states the checking and adjusting method of valve timing and valve clearance.

并介绍了配气相位和气门间隙的检查调整方法.
