heavy truck exhaust pipe intake pipe

Shengkunda provides the heavy truck exhaust pipe intake pipe (Model VG2600111136) as a precision-engineered solution for heavy-duty exhaust management. This HOWO Truck Engine Spare Part Engine Rear Exhaust Manifold is installed between the engine cylinder head and the turbocharger, acting as a high-strength conduit for combustion by-products. As a durable Sinotruk Spare Parts Vg2600111136 Rear Exhaust Manifold, it prevents exhaust gas backflow from compromising cylinder combustion efficiency. The unit is designed to maintain structural integrity under extreme thermal cycles, ensuring stable air flow and reducing the risk of manifold cracking in demanding logistics environments.

Product Parameters

Key Features and Advantages

● Optimized Fluid Dynamics
The internal flow channel is designed to minimize exhaust turbulence and lower back pressure. This optimization ensures a faster turbocharger spool-up and improves overall fuel combustion efficiency.

● Extreme Thermal Resilience
The manifold is cast from heat-resistant alloys capable of withstanding continuous operating temperatures up to 1000°C. This prevents warping and ensures a leak-free seal between the cylinder head and the turbocharger.

● Precision Flange Sealing
CNC-milled flange surfaces provide an ultra-flat interface for mounting gaskets. This high-precision finish eliminates exhaust leaks that can lead to power loss and increased cabin noise.

● Internal Stress Elimination
Every unit undergoes a specialized aging treatment to stabilize the molecular structure of the metal. This process prevents the heavy truck exhaust pipe intake pipe from deforming or cracking due to the repeated expansion and contraction of the engine bay.

Applications

This heavy truck exhaust pipe intake pipe is specifically designed for the Sinotruk HOWO TX, NX, T7, and N7 truck models. It is a direct-fit replacement for heavy-duty engines requiring a rear-mounted exhaust manifold configuration, suitable for both long-haul freight and engineering transport vehicles.

Manufacturing Process

Investment Casting (Lost Wax Method)
The heavy truck exhaust pipe intake pipe is formed using high-precision molds with an IT8 accuracy level. This ensures that the internal walls are smooth and the external dimensions meet strict original equipment parameters.

Constant Temperature Aging Treatment
Components are held at a constant 450°C for 20 hours. This critical step eliminates internal casting stresses, ensuring the manifold remains dimensionally stable throughout its service life.

Precision CNC Machining
All mounting surfaces and positioning pin holes are processed using CNC milling machines. We maintain a positioning hole tolerance of ±0.02mm to ensure a perfect alignment during engine assembly.

Quality Assurance

1. Hydraulic Pressure Verification
Each manifold is subjected to a 0.5MPa water pressure test for 5 minutes. This ensures the casting is completely dense with zero leakage under operational pressures.

2. Non-Destructive X-Ray Inspection
We utilize X-ray detection to inspect the internal structure of the manifold. This process identifies any hidden shrinkage or microscopic cracks that could lead to premature failure in the field.

3. Extreme Thermal Cycle Testing
Units are subjected to 100 cycles of temperature fluctuations ranging from -40°C to 1000°C. This rigorous test confirms that the heavy truck exhaust pipe intake pipe will not deform or crack under the most severe operating conditions.
