Crankcase lower part

1. A supercharged internal combustion engine comprising:

a crankcase lower part extending about a space below a crankshaft;

a crankcase upper part;

at least one intercooler cooling charged air from a first compressor by coolant;

a charge air intermediate cooler cooling charged air from a second compressor by coolant;

a plate that adjoins the crankcase upper part;

wherein said at least one intercooler and/or said charge air intermediate cooler is integrated and secured to said plate, and

an oil sump that adjoins said plate and together therewith forms said crankcase lower part.

2. A supercharged internal combustion engine according to claim 1 , wherein said intercooler and/or charge air intermediate cooler is at least partially monolithically formed with said plate; wherein said plate is a yoke plate.

3. A supercharged internal combustion engine according to claim 1 , wherein said intercooler and/or charge air intermediate cooler is at least partially monolithically formed with said plate; wherein said plate is a bearing plate.

4. A supercharged internal combustion engine according to claim 1 , wherein said intercooler and/or charge air intermediate cooler contains a first chamber that guides the coolant, and a second chamber that guides the charge air and is closed off relative to said first chamber, wherein said first chamber is incorporated into a coolant circuit via a coolant inflow and a coolant outflow, and wherein said second chamber communicates via a charge air supply line with the pressure side of a compressor that provides the charge air, and communicates via a charge air discharge line with a charge air header pipe or with the intake side of a further compressor.

5. A supercharged internal combustion engine according to claim 1 , wherein a wall separates said first chamber from said second chamber and has a maximized heat exchanger surface.

6. A supercharged internal combustion engine according to claim 1 , wherein said intercooler and/or said charge air intermediate cooler is tubular.

7. A supercharged internal combustion engine according to claim 6 , wherein said intercooler and/or said charge air intermediate cooler is formed from an outer tube, through which charge air flows, and a cooling insert, through which the coolant flows, or wherein said intercooler and/or said charge air intermediate cooler is formed from an outer tube, through which the coolant flows, and an insert, through which charge air flows.

8. A supercharged internal combustion engine according to claim 7 , wherein said outer tube is secured to the plate.

9. A supercharged internal combustion engine according to claim 7 , wherein said outer tube is monolithically formed with the plate.

10. A supercharged internal combustion engine according to claim 1 , wherein the internal combustion engine is provided with exhaust gas recirculation, and wherein for cooling recirculated exhaust gas, an exhaust gas recirculation cooler, which is cooled by a coolant, is integrated into said crankcase lower part.

11. A supercharged internal combustion engine according to claim 1 , wherein at least one charge air pipe is integrated into said crankcase lower part such that said at least one charge air pipe leads from a first side of said crankcase lower part to a second side thereof.
