Weichai J135A/W58T Urbo -compressor

Product representation

1. Introduction to turbocharged technology

The turbocharged J135A/W58T is an innovative device that uses the energy of the exhaust gases of the engine to compress the incoming air. This allows you to increase the air density in the combustion chamber, increase the engine power by 30–40% and reduce fuel consumption by 3-5%. The technology is based on the principle of converting the kinetic energy of gases into mechanical work, which is achieved by combining the turbine and compressor on a common shaft.

2. The design of the turbocharged j135a/w58t

Turbocharged consists of three main components:

Turbine

Function: converts the energy of the exhaust gases into a rotational movement.

Design:

Blades: titanium alloy products (TI-6L-4V) with an aerodynamic form that provides maximum efficiency.

Corps: power steel with anti -corrosion coating (zincing + epoxy paint).

Balancing: carried out to G2.5 (ISO 1940) to minimize vibrations.

Compressor

Function: squeezes air and directs it into the engine.

Design:

Lapes: magnet -packed with laser -leveled ribs.

Rotation camera: optimized geometry for reducing energy water.

Burning group

Function: Holds the shaft in the working position and provides smooth rotation.

Design:

Air-oo-resistant bearings: use a combination of pneumatic and liquid suspension.

Lubrication system: automatic lubricant through motor oil (guarantees work up to 180,000 rpm).

3. Detailed working cycle

Stage 1: The entry of exhaust gases into the turbine

Gase temperature: up to +850 ° C.

Pressure: 1.2–1.5 bar.

Process:

Gases are entered through a special pipe in the turbine.

The turbine blades rotate under the influence of gases, transmitting rotation to the shaft.

Stage 2: Compressor stage

Rotation of the shaft: 180,000 rpm.

Compressor:

Highs air through an air filter.

Squeezes the air to a pressure of 0.3-0.5 bar.

Compressed air temperature: +150 ° C.

Stage 3: Air cooling in the heat exchanger

Heat exchanger:

Uses a coolant (water or solo solution).

The air temperature is reduced to +50 ° C.

Air density increases by 20–25%.

Stage 4: Clusted air intake to the engine

Combustion chamber:

Compressed air is mixed with fuel.

The increased air density allows you to burn more fuel, increasing power.

Stage 5: operating modes and regulation

(Bypass value):

It opens with excess pressure (for example, 0.8 bar).

Part of the gases is sent to the exhaust, preventing the wear of the turbine.

T UrboCharger Control Unit (TCU):

Automatically regulates the pressure of the infusion depending on the load of the engine.

4. Technical solutions to increase efficiency

4.1. Aerodynamic modeling

CFD analysis:

Computer modeling of air and gases.

Optimization of the shape of the blades for minimizing funnels and turbulence.

Results:

The effectiveness of turbocharged: 66–72%.

Maximum performance: 25 kg/min.

4.2. Materials and production technologies

Titanium blades:

Reducing weight by 30% compared to steel.

Corrosion resistance and high temperatures.

Ceramic coating:

On turbine blades (thickness 0.2 mm).

Hardness: HRC 60–62.

4.3. Lubrication and cooling system

Lubrication:

Synthetic lubricant (Castrol GTX 20W-50).

Replacing every 1000 hours of work.

Cooling:

Two -stage heat exchanger (water + air).

Temperature regime: -40 ° C → +120 ° C.

5. Environmental friendliness and energy efficiency

5.1. Reducing emissions

NOX: -15% (through the EGR system).

Co₂: -20% (due to complete combustion).

SCR technology:

Additional gas purification using ammonia.

5.2. Fuel saving

Example:

Weichai WP12 engine (336 hp):

Without turbocharged: consumption 38 l/100 km.

With turbocharged: consumption 36.5 l/100 km.

6. Testing and certification

6.1. Laboratory tests

Wear test:

10,000 loading cycles (90% of the maximum power).

Vibration test:

100,000 cycles with an amplitude of 2 mm (frequency 50 Hz).

Climate tests:

100 cycles of temperature differences (-40 ° C → +80 ° C).

6.2. Certification

ISO 4548-12: International standard for turbocharges.

IMO Tier II: the world standard of environmental friendliness.

CCS: Chinese court registration (for marine applications).

7. Application in various industries

7.1. Cargo transport

Advantages:

Increasing traction when driving on steep lifting.

Fuel saving on intercity routes.

7.2. Shipbuilding
