C. engine is attached troops to a unit high pressure supercharging device and low-pressure supercharging device.The high pressure supercharging device comprises high-pressure turbine, and the exhaust flow that leaves motor reduces pressure therein.High-pressure turbine drives high pressure compressor, and the high pressure compressor compression will be delivered to the combustion-air flow of motor.Between high pressure compressor and motor, also be connected with charger-air cooler.Low-pressure supercharging device has low-pressure turbine, leaves the exhaust flow decompression more therein of high pressure turbine.Low-pressure turbine drives low pressure compressor, be transported to combustion-air flow in the motor therein by precompression by high pressure compressor.Between low pressure compressor and high pressure compressor, be connected with another charger-air cooler usually at this.
For the internal-combustion engine with two-stage exhaust-gas turbocharger, so the motor of internal-combustion engine attaches troops to a unit two supercharging devices arranged, i.e. high pressure supercharging device and low-pressure supercharging device, and they all must be structured on the motor according to prior art.If the V-shaped layout of motor, each bank of cylinder of motor has independent exhaust-gas turbocharger, thereby the quantity that will be fixed on the supercharging device on the motor for the exhaust-gas turbocharger of two-stage is brought up to four, and a high pressure supercharging device and a low-pressure supercharging device are promptly respectively arranged on each bank of cylinder.
Improve if fix or be placed in the quantity of the supercharging device on the motor, this is owing to the space requirement that is not unconspicuous supercharging device causes installation question so.The intensity of internal-combustion engine and vibration performance are subjected to negative effect in addition.
Summary of the invention
The problem of the present invention of setting out thus is, proposes new-type internal-combustion engine.
This problem solves by the internal-combustion engine according to claim 1.According to the present invention, low-pressure supercharging device is made of independent module and separates with motor, and low-pressure supercharging device is placed on the independent framework or frame.
The present invention proposes, and for having the internal-combustion engine of two-stage exhaust-gas turbocharger at least, low-pressure supercharging device constitutes as independent module and separates with motor, and low-pressure supercharging device is placed on the independent supporting frame or support frame.The intensity of internal-combustion engine and vibration performance do not change with respect to the single stage supercharging internal-combustion engine by this way.Avoided installing or assembling the space problem of low-pressure supercharging device.Because low-pressure supercharging device constitutes as independent module,, and need not on motor or high pressure supercharging device, to carry out structural change so the existing internal-combustion engine that has the low exhaust-gas turbocharger of single-stage can replenish equipment simply.
Preferably, the high pressure supercharging device is placed on the common framework or frame with motor, and its mesohigh supercharging device and motor are used as a module especially and constitute.
Advantageous modification of the present invention is provided by dependent claims and following description.
