Embodiment Construction

[0013] Coolant conduits have been provided in the engine block to dissipate the heat generated during combustion operation. Furthermore, the development of modern internal combustion engines is aimed at tighter construction as well as engine power gains. In order to be able to obtain a compact configuration of the cylinder block into which the cylinder bores extend from the upper side, the cylinder bores may be arranged closely together in the cylinder block, which results in an arrangement between two adjacent cylinder bores The width or thickness of the web (web) decreases.

[0014] However, due to their proximity to combustion operation in internal combustion engines, said webs are thermally and mechanically exposed to certain loads. Proposals aimed at increasing the cooling of webs arranged between two adjacent cylinder bores are known from the prior art.

[0015] For example, EP 2 325 453 B1 describes an internal combustion engine with a coolant circuit which is divided...

Abstract

The present application provides a cylinder block of an internal combustion engine, the internal combustion engine and an engine cooling system. The cooling system includes: a cylinder bore including a central axis; a coolant conduit including a first section positioned on a first side of the cylinder bore and a second section positioned on a second side of the cylinder bore; a connecting conduit , which extends between the first section and the second section and includes a first end leading to the first section and a second end leading to the second section. The connecting pipe includes a first segment and a second segment extending inward toward the central axis, and the intersection of the first segment and the second segment on a plane perpendicular to the central axis forms a non-right angle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102017206716.0 filed on April 21, 2017. The entire contents of the above-referenced applications are hereby incorporated by reference in their entirety for all purposes. technical field [0003] The present description generally relates to a cylinder block of an internal combustion engine having a cooling system. Background technique [0004] In the field of internal combustion engines it is known to allow cooling in a coolant circuit to flow independently through the engine block and the cylinder head of the internal combustion engine. The cylinder head, which is in particular thermally connected to the combustion gases via the combustion chamber and duct walls, and in particular the engine block, which is thermally connected to the friction points, can thus be cooled differently. A system that allows the cylinder head and block to be cooled separat...
