High Performance Turbocharger Bracket 3051793 For Cummins

The main body is forged from SAE 4340 chromium-molybdenum steel, vacuum quenched and tempered, with a tensile strength of ≥1200MPa and a temperature resistance limit of 650°C, which is 80% higher than that of ordinary cast steel brackets, and adapts to high-temperature exhaust environment of the turbine (peak temperature of 600°C).

Adopting multi-rib topology, the thickness of key stress points is increased to 12mm, and the deformation is ≤0.05mm after 100,000 times of high-frequency vibration test (amplitude ±2mm, frequency 200Hz), which effectively suppresses the NVH problem of the turbine system.

The bracket is corrected by dynamic balance (residual unbalance ≤1.5g-mm), combined with the design of weight reduction holes (weight reduction of 15%), which reduces the rotational moment of inertia, improves the response speed of the turbine, and reduces the phenomenon of turbine hysteresis.

Surface aluminium plating treatment (thickness 20μm), salt spray corrosion resistance up to 2000 hours (ASTM B117 standard), to adapt to marine engineering, mining and other highly corrosive working conditions.

Generator sets: matched with KTA38-G5 diesel generator sets, guaranteeing turbocharging pressure stability (1.8-2.2Bar) under 1500r/min continuous operation, reducing black smoke emission by 30%.

Construction Machinery: Matching with QSK19 engine for mining dump trucks, it can withstand frequent start-stop shock loads and extend the life of turbo bearings to 12,000 hours (2 times higher than that of sub-factory parts).

Transportation: Suitable for heavy trucks equipped with NT855 engines, optimising the piping layout of the exhaust gas recirculation (EGR) system to reduce airflow turbulence loss.

Intelligent O&M compatibility: OEM data is pre-loaded into the Cummins Insite diagnostic system, real-time monitoring of bracket stress status, and the accuracy of triggering the warning code SPN 5246-31 is increased to 99%.
