    Abstract: A large engine, in particular a marine engine or engine for power plants, and a method of lubricating the engine with injectors. According to the method there are provided one flowmeter for all injectors in the engine, one flowmeter for all injectors in a cylinder or one flowmeter for each injector in the engine. The method comprises the steps of measuring with the at least one flowmeter the lubricant flow, transforming in the controller the measured actual flow into an actual amount, comparing the calculated actual amount to the desired value, and controlling the injectors and adjusting the setting thereof in order to regulate the amount to the desired value for lubricant amount to be injected for a specific operation mode.

    Abstract: Safety system for lubrication of the cylinder of a large slow- running internal combustion engine and a large slow- running two-stroke internal combustion engine A system for lubrication of the cylinder (1) of a large slow-running internal combustion engine. The lubrication system comprises a plurality of lubricant injectors (4) of which each one is connected via one of a corresponding plurality of lubricant supply lines (9) to a lubricant pump unit (11). The injectors (4) have an injection pressure level at which the injectors (4) are activated for ejecting lubricant. Each of the plurality of lubricant supply lines (9) is connected to an upstream side of one of a corresponding plurality of overpressure relief valves (16) for opening the overpressure re- lief valve (16) when the pressure in the corresponding lubricant supply line (9) exceeds a predetermined overpressure relief level which is above the injection pressure level. The downstream sides of all overpressure relief valves (16) are connected to a common overpressure detection device (17, 19, 26), which is configured for giving a signal when a pressure in any one of the plurality of lubricant supply lines (9) exceeds the predetermined overpressure relief level. In particular, the overpressure relief valves (16) are provided remotely from the lubricant pump unit (11) and are communicating only by pipes (9, 15) via the lubricant supply lines (9) to the lubricant pump unit (11).
