Cylinder head of an internal combustion engine with integrated exhaust manifold and cooling jacket

Abstract

The invention relates to a cylinder head of an internal combustion engine, with at least an integrated exhaust manifold. The exhaust manifold comprises: a, at least two conduits that direct the exhaust gas, which are arranged substantially side by side with respect to each other and are collected at the flow connection portion upstream of the exhaust manifold outlet to the manifold line, respectively, which passes through the wall Of the terminal areas are separated from each other; and b, at least one coolant jacket disposed above and / or below at least and having an upper dividing wall and a lower dividing wall, wherein the at least one coolant jacket and the pipe are separated from each other by a common dividing wall The coolant jacket is passed through the coolant in a fixed flow direction, wherein at least one tab extends between the upper dividing wall and the lower boundary wall in the coolant jacket, which has an upstream flow in the upstream; the influent flow being separated by a flow of coolant, wherein the coolant flow is accelerated downstream of the partition in a first zone of the coolant jacket, wherein the portion of the first zone or tab directly adjacent to the inflow surface is arranged directly at and / or on the mobile connection site and / or the terminal area.

Description

technical field [0001] The invention relates to a cylinder head of an internal combustion engine with an integrated exhaust manifold and cooling jacket. Such a cylinder head is produced in particular by a casting method, in which a plurality of exhaust-gas-carrying lines of the exhaust manifold and the cooling jacket are integrated in a one-piece component. The exhaust-gas-conducting line and the cooling jacket have a common boundary wall made of cast material. Background technique [0002] Such a cylinder head is used in particular as part of an internal combustion engine of a motor vehicle, for example a diesel engine, a gasoline engine or a hybrid engine. The heat released during the combustion of fuel in the combustion chamber of the internal combustion engine or motor block is emitted partly via the walls of the motor block to the cylinder head and partly via the exhaust gas flow to adjacent components and the environment place. In order to avoid thermal overloading ...
