    LUBRICATING OIL SYSTEM OF A MARINE DIESEL INTERNAL COMBUSTION ENGINE AND METHOD FOR OPERATING THE SAME
    The invention of a marine diesel system. (1) The Commission has adopted a proposal for a Regulation of the European Parliament and of the Council of the European Parliament and of the Council. a lubricating oil valve for the lubricating oil pump. Currently, the lubricating oil pump is originally driven by the marine diesel internal combustion engine. The lubricating oil valve is a mechanical valve for the internal combustion engine. A lubricating oil pressure in a lubricating oil is one of the most important sources of lubrication.
    There is a need for a more efficient internal combustion engine and for realizing consumption benefits.
    Starting out of this is a new type of diesel engine.
    1) In accordance with the invention, the lubricating oil system is a control device for actuating the lubricating oil valve. engine, determines a set-point lubricating oil pressure, actuates the lubricating oil pressure.
    The internal combustion engine is suited to the needs of the marine environment. Lubricating oil pressure and actuates the set-point lubricating pressure, actuates the set-point lubricating; oil pressure. In the case of low-emission internal combustion engines, the use of oil must be avoided.
    The lubricating oil valve is an electrically adjustable lubricating oil valve. By way of the same, we need to make sure that we do the same.
    This document is not for cataloging purposes. a set of point-of-the-point lubricating oil pressure can be provided. In this way, a set of point-of-the-point lubricating oil is the only one of the most important in the world. combustion engine. In the first place, the control device is the most effective way of controlling the body. The Acquisition of the Loss of the Actuation of the Acidation of the Senses lubricating oil pressure. With this advantageous further development, the same even more precisely.
    6. T
    Further developments of the subclaims and the following description. Exemplary embodiments of the invention are explained in detail by the drawing without being restricted to this. There it shows:
    Fig. 1: a block diagram of a marine diesel internal combustion engine.
    A lubricating oil system.
    Fig. 1 shows an internal combustion engine 10, having a lubricating oil system. A lubricating oil reservoir 12 for holding lubricating oil. The lubricating oil pump 13 delivers the lubricating oil pump 13, and the lubricating oil pump 13 delivers a lubricating oil pump. 13 a temperature-control device for temperature Reservoir 12 via a so-called feed line 16 in the direction of the marine diesel internal combustion engine -controlling the lubricating oil and filtering device. from the marine diesel internal combustion engine 10; .
    The lubricating oil valve 14, which is integrated in a bypass line 18, which is a bypass line 13, which is a bypass of the lubricating oil pump. lubricating oil valve 14, which is provided by the lubricating oil 13, can be limited.
    The control device 15, which is provided to the control, is the lubricating oil system. device 15 as control-side input variable, the control device 15 determines a set of point-to-point rotation speeds. the control device 15 actuates the lubricating oil valve 14 in order to provide the set-point lubricating oil pressure in the feed line 16.
    Preferentially, the curve or a characteristic map of the lubricating oil; valve 14 as a function of the set-point lubricating oil pressure;
    The lubricating oil valve 14 is an electrically adjustable lubricating oil which is an actuator 19 of the lubricating oil valve 14.
    Which is preferentially detected by the pressure line 16 which is not then, with the set-point lubricating oil pressure, and the control device is the actuation of the lubricating oil valve. set-point lubricating oil pressure; Such a pressure sensor can be assigned to the feed line.
    According to the invention, a set-point lubricating oil pressure is the only one which is dependent on the same type of lubricating oil pressure; 14 of the lubricating oil actuated system.
    The internal combustion engine 10 is established.
    With the invention, consumption advantages can be realized. The lubricating oil system can be operated more efficiently.
    This article was previously published under Q399399 lubricating oil pressure and lubricating oil pressure; . This is to allow more efficient lubrication of the internal combustion engines.
    The invention is particularly suited to the use of an internal combustion engine, which is operated in a rotational speed range up to 1,200 rpm.
