Definitions

• the present invention relates to a cylinder block with an EGR cooler housing which has housing and parts in which the EGR cooler can be mounted on the engine cylinder block.
• EGR exhaust gas recirculation
• EGR cooler By means of EGR system, combustion temperature is reduced, and the generation of nitrogen oxide gas is decreased.
• EGR cooler is used in order to send more gas to the combustion chamber by increasing the density of the gas.
• EGR cooler is placed different places around the engine depending on the engine package, and it is fixed on placed where it is located differently. Connecting members and carriers have to be placed around the engine for the mounting of EGR cooler, and these procedures cause additional weight and space loss.
• the EGR coolers used today are mostly fixed somewhere close to the engine or somewhere on the engine. A connection is made between the place where the EGR cooler is fixed and the engine, and thus exhaust gases are enabled to be cooled.
