114400-4380 114400-4381 Turbocharger RHG6 Turbo for ZX330-3 ZX360-3 CX360 Excavator 6HK1XQB Engine

Fitted onto the engine of an excavator, the turbocharger is an exhaustgasdriven air compressor. Its core purpose is using waste exhaust energy to compress intake air, promoting more thorough combustion of diesel fuel, thus significantly lifting power output, lessening fuel consumption and reducing black smoke release amounts.

Core Functions

Power Boost PerformanceTurbocharging increases power by 30%–50% and torque considerably for samedisplacement engines, supporting powerful performance during heavyload construction work and uphill travel.

FuelSaving & Emission Optimization PerformanceAdequate intake air supports complete fuel combustion, lowering fuel consumption by roughly 5% and decreasing black smoke, carbon monoxide and HC emission concentrations.

LowSpeed Torque Upgrade PerformanceHigher lowrpm torque offers greater working strength for excavator heavyload startup and digging operational tasks.

Basic Structure (Three Critical Component Assemblies)

Turbine End (Exhaust Side Assembly Unit)Connected to the exhaust manifold, highheat exhaust gas at 600–900 ℃ strikes the turbine wheel, rotating the central shaft at 100,000–200,000 rpm.

Compressor End (Intake Side Assembly Unit)Coaxially driven by the turbine shaft, the compressor impeller compresses air purified by the air filter and feeds pressurized air into engine cylinders.

Central Hub (BearingCoolingLubrication Unit Assembly)Equipped with floating bearings and engineoil heatdissipationlubrication flow passages, it resists extreme high temperatures and ultrahigh rotational speeds. Engine oil dissipates heat to prevent bearing sintering damage faults.

Working Principle (4Stage Functional Cycle Process)

Exhaust GasActuated Rotation StageHightemperature highpressure engine exhaust enters the turbine housing and spins the turbine impeller rapidly.

Coaxial Synchronous Rotation StageThe turbine shaft turns the compressor wheel at the same ultrahigh rotational speed.

Air Pressurization Compression StageThe compressor sucks filtered ambient fresh air and compresses it to 0.1–0.2 MPa with air temperature elevation.

Intercooler Cooling Treatment StageHeated compressed air is cooled by the intercooler to increase air density, then enters cylinders for increased fuel injection volume and higher power output levels.
