摘要： Method for injecting fuel (14a) into a combustion chamber having at least two fuel injectors (12a, 12b, 12c) of a cylinder (11) of a reciprocating internal combustion diesel engine in underload operation comprises alternately injecting the fuel so that during at least two successive working cycles no fuel is injected by at least one of the fuel injectors and during at least two following successive working cycles no fuel is injected by the other fuel injector. An Independent claim is also included for a reciprocating internal combustion engine operated by the method. Preferred Features: Each combustion chamber has two, three or four fuel injectors.

摘要： PROBLEM TO BE SOLVED: To provide a method for operating a reciprocating internal combustion engine, particularly, a large diesel engine, and further a reciprocating internal combustion engine to be operated by this method.
SOLUTION: The method is provided to operate a longitudinally scavenging reciprocating internal combustion engine (1), particularly, a large diesel engine. The reciprocating internal combustion engine includes a cylinder (2) having and outlet valve (3) and a scavenging opening designed in the form of a scavenging slot (4), the cylinder being configured so that a piston (5) reciprocates therein along a traveling surface (6) between a bottom dead center (UT) and a top dead center (OT); and a supercharger group (7) for compressing air (11), including a turbine (9) driven by exhaust gas (8) from a combustion chamber (22) of the cylinder. The compressed air is supplied as scavenging air (12) through the scavenging slot to the combustion chamber of the cylinder. When the internal combustion engine is operated in a low-load operation area, the outlet valve (3) is opened, subsequently to combustion step, to introduce exhaust gas (8) to the supercharger group (7).

摘要： PROBLEM TO BE SOLVED: To provide a method of machining for forming a sliding surface on a cylinder wall of a cylinder liner of a piston type combustion engine, in particular low-speed large diesel engine of the two stroke type, where a piston is arranged in a cylinder liner and reciprocates in the cylinder axis direction. SOLUTION: The method of machining includes a step for providing a cylinder liner material and a step for cutting cylinder wall 2 using a cutting tool, forms a capillary-like fine structure 6 having circumferential capillaries 61 on the cylinder wall 2 in a fine-machining step, and extends the capillary-like fine structure 6 helically along the cylinder axis 4 of a cylinder liner 3. The method of machining forms cross connections between the circumferential capillaries 61 of the capillary-like fine structure 6 by a transverse machining method so that the capillary-like fine structure 6 is substantially maintained.
