Lubricating oil injector used in a large low-speed two-stroke engine and having a quenching valve seat and manufacturing method

摘要

Injectors for injection of lubrication oil into the cylinder of a large slow-running two-stroke engine, especially marine diesel engine, proved better uniform performance the when using hardened surfaces for the plain bearing in which the valve member slides. Also, hardened surfaces for valve seats at the nozzle was an improvement
