PURPOSE:To inject oil with correspondence to the engine rotation through simple structure by communicating the working oil feed path to a cylinder oil injector with a working oil feeding system in hydraulic drive mechanism of engine exhaust valve. CONSTITUTION:A cylinder injector 10 for feeding lubricant to the cylinder liner 7 of engine is provided. The working oil feed path 27 to the cylinder oil injector 10 is communicated to the working oil feeding system 28 in hydraulic drive mechanism for exhaust valve 17 of engine E. The hydraulic drive mechanism for exhaust valve 17 is constructed with upper and lower exhaust valve moving systems 16, 15. Pressure variation in hydraulic drive mechanism for exhaust valve 17 of engine E can be utilized as the operating source of cylinder oil injector 10. Consequently, oil injection corresponding with engine rotation can be achieved through simple structure. |
