Embodiment Construction

[0096] exist figure 1 , 2 In and 3, a plurality of fuel injectors 3 are shown, which are arranged on the cylinder liner 5 at an appropriate interval. These injectors are arranged to open at a certain pressure in the oil delivery line 2 from the lubricating device 1 to the respective injector 3 .

[0097] At the end of the fuel injector 3, close to the inner surface of the cylinder, a nozzle 4 is installed, which has a nozzle hole, and when the pressure in the oil delivery pipeline 2 reaches a preset value, the oil is atomized through the nozzle hole. Alternatively, the oil can be sprayed without atomization.

[0098] Oil is supplied to each oil delivery line 2 from a lubricating device 1 consisting of a plurality of small pumps, one for each oil delivery line 2 , receiving oil from an oil reservoir 7 .

[0099] The oil pump is capable of delivering a quantity of oil at given time intervals and can be, for example, a conventional timed cylinder lubricator as disclosed in In...

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 numberof 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 thelubricating oil before injection into the cylinder; and controlling the temperature regulation of the lubricating oil in dependence of the temperature of the cylinder linings (5) and the temperatureof 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.

Description

technical field [0001] The invention relates to a method for quantitatively injecting lubricating oil into a cylinder, preferably a cylinder of a two-stroke diesel engine, such as a marine engine, the method comprising the steps of: [0002] - the lubricating oil is delivered under pressure from the lubricating oil reservoir via the pressure lubrication system to the injectors arranged in the cylinder wall, a plurality of injectors are used, each injector is adapted to inject a certain amount of lubricating oil into in each cylinder; [0003] - Create data representing the temperature of the lubricating oil in the injector, cylinder liner or injector, or a combination thereof; [0004] - store the temperature data in the computer; [0005] - creation of at least one computer-controlled thermoregulation unit associated with the incoming lubricating oil to establish thermoregulation of the lubricating oil before it is injected into the cylinder; [0006] The invention also in...
