ABSTRACT:
A method for preventing damage to valve faces and valve seat faces and also for preventing partial gas escape, which is mainly caused by solid particles generated by the reaction between incomplete combustion materials produced during engine operation and additive agents included in lubricant oils as well as by adherence of metal dust on the faces by filtering out selected particles.
The solid particles are produced by the reaction of carbon as an incomplete combustion material in an engine with calcium, zinc, phosphorus, magnesium and so on which are included in the additives of the lubricant oils as well as with solid impurities generated by incombustibles included in fuel, and also with metal dust. Particles and impurities bigger than 1 .mu.m are removed by filter device composed of many piled thin papers, while the same smaller than 1 .mu.m are retained in the lubricant oil. The valve face and the valve seat face surfaces are maintained clean and smooth.
