    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: The method comprises steps for delivering lubricating oil under pressure from a lubricating oil reservoir (7) via a forced lubrication system to injectors (3) provided in the cylinder walls. A number of injectors (3) are used, each adapted for injecting a dosed amount of lubricating oil into each cylinder. The method further includes steps of: - establishing data indicating the temperature of cylinder linings (5); - establishing data that indicate the temperature of the lubricating oil in the lubricating oil reservoir (7); - storing the temperature data for cylinder linings (5) and the lubricating oil in a computer; - establishing at least one temperature regulating unit (9) controlled by the computer and connected with the delivered lubricating oil for establishing a temperature regulation of the lubricating oil before injection into the cylinder; - controlling the temperature regulation of the lubricating oil in dependence of the temperature of the cylinder linings (5) and the temperature of the lubricating oil in the lubricating oil reservoir (7), as the computer controls heating/cooling in the temperature regulating unit (9) for influencing the viscosity of the lubricating oil such that a uniform injection independent of the temperature of the cylinder linings (5) is established.

    Abstract translation: 该方法包括以下步骤：在润滑油储存器（7）的压力下经由强制润滑系统将润滑油在压力下输送到设置在气缸壁中的喷射器（3）中。 使用多个喷射器（3），每个喷射器适于将定量的润滑油喷射到每个气缸中。 该方法还包括以下步骤： - 建立指示气缸衬套（5）的温度的数据; - 建立指示润滑油储存器（7）中的润滑油的温度的数据; - 将气缸衬套（5）和润滑油的温度数据存储在计算机中; - 建立至少一个温度调节单元（9），所述温度调节单元（9）由所述计算机控制并且与所输送的润滑油连接，用于在注入所述气缸之前建立所述润滑油的温度调节; - 根据计算机控制温度调节单元（5）中的加热/冷却，根据缸衬（5）的温度和润滑油储存器（7）中的润滑油的温度来控制润滑油的温度调节 9）用于影响润滑油的粘度，使得不依赖气缸衬套（5）的温度的均匀喷射被建立。
