Title:
シリンダに潤滑油を注油する方法及びシステム
Document Type and Number:
Japanese Patent JP6574440
Kind Code:
B2
Abstract:
There is disclosed a system for dosing lubricating oil into cylinders, preferably in twostroke diesel engines, for example marine engines. The system includes: - injection units (251) provided in the walls (57) of the cylinders as a number of injection units are used for each cylinder; - a lubricating apparatus (252) for delivering a dosed amount of lubricating oil under pressure to the injection units; - means (56) for detecting the load of the engine; - an exhaust valve (55) connected to an actuator (53) for displacing the exhaust valve; and - a control unit (50) for electronic control and timing of the closing time of the exhaust valve of the cylinder, depending on detection of the engine load, as a signal is transmitted to the actuator, and as an adjustment of the closing time of the exhaust valve in relation to the actual engine load is performed. The control unit is also adapted to electronic control and timing of the lubricating oil delivery. In order to possibly improve engine emission and enhance utilisation of the lubricating oil, the system further includes: - a connection (44) between the means (56) for detecting the engine load and the control unit (50) for transferring the detected data; and - a connection (43) between the control unit (50) and the lubricating apparatus (252) for transferring a control signal to the lubricating apparatus for adjusting the timing of the lubricating oil delivery in dependence of the engine load.
