Description

 

The 424-3429 and 20R-3861 turbochargers are key performance-enhancing accessories tailored for CAT C9.3 diesel engines, primarily deployed in large excavators for construction, mining, and heavy-duty earthmoving tasks. As a core component of the engine’s intake system, it boosts air pressure entering the combustion chamber, enabling more efficient fuel combustion and significantly enhancing engine power output.
Manufactured in strict compliance with CAT’s OE standards, these turbochargers integrate a high-speed turbine, compressor, and precision bearing system, all calibrated to match the C9.3 engine’s operating parameters. Each unit undergoes rigorous dynamic balance testing, pressure resistance detection, and endurance trials to ensure seamless compatibility with excavator engine bays. It effectively adapts to the high-load, frequent start-stop working conditions of excavators, avoiding issues like turbo lag or premature failure caused by substandard components.

 

 

Advantage

  • Perfect C9.3 Engine Compatibility: Exact match for CAT C9.3 excavator engines, with consistent flange size, oil inlet/outlet interfaces, and mounting points. Plug-and-play installation shortens maintenance downtime by 50% compared to non-OE alternatives.
  • High-Strength & Wear-Resistant Construction: Turbine wheel made of heat-resistant Inconel alloy, compressor wheel of forged aluminum alloy, and bearings lubricated by a precision oil circuit. Resists high temperatures (up to 950°C) and high-speed wear, service life extended by 60% vs. generic turbochargers.
  • Optimized Boost Efficiency: Advanced aerodynamic design ensures rapid boost pressure build-up (reaching rated pressure in 0.3s), eliminating turbo lag. Improves engine intake efficiency by 35%, laying the foundation for enhanced power and fuel economy.
  • Enhanced Operational Reliability: Equipped with a built-in oil filter and temperature control valve, preventing impurities from damaging internal components and stabilizing operating temperature. Reduces turbocharger failure rate by 70% in dusty, high-load excavator scenarios.


Performance

  • Power & Torque Enhancement: Boosts C9.3 engine power by 20-25% (up to 370 HP) and peak torque by 25-30% (up to 1600 N·m). Enables excavators to achieve 15-20% higher digging force and faster cycle times, significantly improving work efficiency.
  • Fuel Efficiency Optimization: By promoting full fuel combustion, it reduces engine fuel consumption by 12-15% under typical excavator working conditions. For a 20-ton excavator, this translates to annual fuel savings of 8,000-12,000 liters.
  • Stable High-Speed Operation: Turbine speed can reach 120,000 rpm, with dynamic balance error <0.005g, ensuring smooth operation without abnormal vibration. Maintains stable boost pressure (1.8-2.2 bar) even under continuous heavy-load work, avoiding power fluctuations.
  • Harsh Environment Adaptability: Dust-proof sealing structure on the compressor inlet and heat-insulating coating on the turbine housing. Works stably in environments with temperature -25°C to 45°C and high dust concentration, ensuring excavator reliability in mining and remote construction sites.
