Embodiment Construction

[0030] The following is a detailed description of exemplary embodiments of the present disclosure. The exemplary embodiments described herein and illustrated in the accompanying drawings are intended to teach the principles of the invention, thereby enabling those of ordinary skill in the art to make and use the invention in many different environments and for many different applications. Therefore, the exemplary embodiments are not intended to be and should not be considered as a limiting illustration of the scope of patent protection. Instead, the scope of patent protection should be defined by the appended claims.

[0031] The present invention may be based in part on the realization that EGR can cause damage to the charge air system, which creates a potential need for easy replacement of damaged components of the charge air system. Accordingly, a new configuration for medium speed engines is disclosed that improves the accessibility / accessibility (ability to access, for e...

Abstract

A charge air guide element (23) and a water ring element (40) for an internal combustion engine are configured to supply cooling water to the water ring element (40) via the charge air guide element (23). Specifically, a cooling water channel system (50A, 50B) may be integrated into a wall structure of the charge air guide element (23) and comprise at least one opening at the cylinder unit side of the charge air guide element (23), which opens towards the top side of the charge air guide element (23), and at least one opening at an access side of the charge air guide element (23), the access side being opposite to the cylinder unit side. Moreover, a specific arrangement of screw guiding holes (64A, 64B) at the charge air guide element (23) may allow using the charge air guide element (23) for internal combustion engines in in-line configuration and in V-configuration.

Description

technical field [0001] The present invention relates generally to internal combustion engines, and more particularly to charge air systems and cooling systems for internal combustion engines. Background technique [0002] Moderate speed internal combustion engines include a large number of components. Some of these components are subject to repairs, eg at components of the cylinder unit, such as the pistons. In addition to physical wear, various components can also be exposed to chemically active substances, such as aggressive fuel and exhaust gases. [0003] Internal combustion engines emit a complex mixture of air pollutants. These air pollutants consist of gaseous compounds such as nitrogen oxides (NOx) and solid particulate matter also known as soot. Exhaust emission standards have become more stringent due to increased environmental awareness, and NO emissions from engines to the atmosphere can be regulated according to engine type, engine size, and / or engine class ...
