道依茨公司FL413F风冷柴油机系列的增压或非增压机型的进气门上安装了该公司视为专利的气门旋转机构。它之所以安装在进气门上,是为了降低进气门的热负荷,改善它的工作条件,以便延长寿命。在进气门上安装旋转机构能有效的清除阀杆与导管间的积炭利防止“卡死”,也可以将锥面及气门杆上的积炭擦掉。这样不但可以改善气门杆的润滑条件,而且对于气门座及导管的导热性也都极为有利。因此气门锥面就不易产生腐蚀磨损和磨损不
The valve rotary mechanism, which the company considers to be patented, is installed on the intake valve of the turbocharged or non-turbocharged version of the Deutz FL413F air-cooled diesel engine. The reason why it is installed on the intake valve, in order to reduce the thermal load on the intake valve to improve its working conditions, in order to extend the life expectancy. Install the rotary valve on the intake valve can effectively remove the accumulation of carbon between the stem and the catheter to prevent “stuck”, you can also the cone and the valve stem on the carbon off. This will not only improve the valve rod lubrication conditions, but also for the valve seat and the catheter thermal conductivity are also extremely beneficial. Therefore, the valve cone is not easy to produce corrosion wear and abrasion does not
