Cummins engine spare parts turbocharger C5603544 in stocked

Built to maximize the performance of Cummins 14L engines, this turbocharger features a twin-scroll turbine design that optimizes exhaust gas utilization. The dual-inlet turbine housing separates exhaust pulses from adjacent cylinders, reducing turbo lag by 30%—ensuring boost pressure reaches 1.0 bar in 0.5 seconds at 1200rpm, delivering immediate low-end torque for heavy-load startups and uphill driving. The compressor wheel uses a backward-curved blade design, achieving a compression efficiency of 78% (15% higher than single-scroll alternatives) and increasing engine power output by 8-10%. By improving air-fuel mixing, it reduces fuel consumption by 5-7% and cuts particulate matter (PM) emissions by 25%, fully meeting strict emission regulations

Engineered to endure the extreme conditions of turbocharged engines (high temperature, high speed), the C5603544 uses high-grade materials for exceptional durability. The turbine wheel is made of Inconel 713C nickel-based superalloy—resisting continuous operating temperatures up to 950℃ and peak temperatures of 1050℃ without deformation. The compressor wheel is crafted from forged aluminum alloy (6061-T6) with a CNC-machined surface, ensuring high rotational stability at 120,000rpm. The bearing housing is made of nodular cast iron (GG40) with an integrated oil cooling jacket, maintaining bearing temperature below 120℃. These materials enable the turbocharger to withstand 100 million operating cycles (equivalent to 1.2 million km) without failure

The turbocharger integrates a high-performance bearing and sealing system to guarantee long-term reliability. It uses a floating journal bearing with a bronze alloy lining, reducing friction by 40% compared to traditional ball bearings and improving oil film stability. The bearing is lubricated by the engine’s pressure oil system (2.5-4.0 bar), with a dedicated oil inlet and return channel that prevents oil coking. A dual-seal design—carbon ceramic primary seal and nitrile rubber secondary seal—prevents oil leakage into the turbine or compressor housing, eliminating blue smoke emissions and oil consumption. The seals also resist high temperatures and chemical corrosion, maintaining integrity for ≥200,000km

Optimized for efficient fleet maintenance, the turbocharger features a plug-and-play design and minimal maintenance requirements. It comes pre-balanced (residual unbalance ≤2g·cm) and pre-assembled with all necessary gaskets and hardware, aligning perfectly with the engine’s mounting points. The 12-pin electrical connector plugs directly into the engine wiring harness, requiring no on-site calibration—two technicians can complete replacement in 3 hours, 40% faster than non-OE turbochargers. The turbocharger’s self-cleaning compressor wheel design reduces carbon deposit formation, eliminating the need for regular disassembly and cleaning. Backed by a 1-year/150,000km warranty, it minimizes replacement frequency and long-term operational costs for fleet operators
