### Contents

• Object of the investigation;

• Purpose and restrictions;

• Optimized parameters;

• Turbocharger;

• Structural analysis;

• Results.

### 1. Object of the investigation

• 1.5L 4-stroke diesel engine;

• 4 inline cylinders

• Ne = 32.7kWt at 4500 rpm

1.1 Diesel engine

### 2. Purpose and restrictions

Purpose:Ne = 82.5kWt

Restrictions:

• Pz= 180 bar;

• Pinj= 2000 bar;

• Matching Euro-5 ecological standard.

### 4.1 Turbocharger

• πk =2.5;

• G = 0.114 kg/s;

• N = 153 000 rpm;

• η = 0.43.

4.1. 3D model of the turbocharger

### 4.2 Turbocharger

Compressor discharge

Charge air cooler

Intake manifold

Exhaust manifold

Turbine inlet

Turbine discharge

4.2. The turbo system operation

### 4.3 Turbocharger

4.3. The turbocharger construction

### 5. Structural analysis

Object: Compressor wheel

Material:aluminum alloy

n = 1.51

5.1. Stress distribution in

the compressor wheel

### 6.1 Results

6.1. Power capacity (Ne) dependence from revolution rate (n)

### 6.2 Results

Euro-5

6.2. NOx emission dependence from revolution rate (n)

### 6.3 Results

Conclusion. As a result of the optimization the significant increase of power capacity and torque was obtained. The negative result is the system complication and more stringent technical maintenance requirements.
