GT2052 727265-0002 Excavator Turbocharger For Perkins T4.40 Diesel Engine

Known as an exhaustpowered air compressor fitted on excavator engines, the turbocharger harnesses waste exhaust gas energy to pressurize intake air. This optimizes diesel combustion completeness, substantially enhancing power output, curbing fuel usage and lowering black smoke release levels.

Core Functions

Power EnhancementSamedisplacement engines obtain 30%–50% more power and notable torque growth via turbocharging, supporting powerful performance under heavy loads and uphill travel.

FuelSaving & Emission RegulationPlenty of intake air ensures full combustion, cutting fuel consumption by approximately 5% and reducing black smoke, CO and hydrocarbon discharge.

LowEnd Torque ImprovementImproved lowspeed torque supplies greater strength for excavator heavyload startup and digging operations.

Basic Structure (Three Major SubAssemblies)

Turbine Side (Exhaust Assembly)Attached to the exhaust manifold, it receives 600–900 ℃ highheat exhaust gas that propels the turbine wheel, spinning the main shaft at 100,000–200,000 revolutions per minute.

Compressor Side (Intake Assembly)Driven coaxially, the compressor impeller compresses air filtered by the air cleaner and delivers boosted air into engine cylinders.

Center Bearing Unit (LubricationCooling Housing)Designed with floating bearings and engineoil heatdissipationlubrication channels, it withstands extreme thermal conditions and ultrafast rotation. Engine oil cools bearings to prevent sintering defects.

Working Principle (4Step Functional Cycle)

Exhaust GasDriven MotionHot highpressure engine exhaust flows into the turbine casing and rapidly rotates the turbine impeller.

Coaxial Supercharging ActionThe turbine shaft drives the compressor wheel to rotate synchronously at high speed.

Fresh Air PressurizationThe compressor inhales cleaned ambient air and compresses it to 0.1–0.2 MPa while raising air temperature.

Intercooler Cooling ProcessHeated compressed air is cooled by the intercooler to increase density, then enters cylinders for extra fuel injection and higher power output.
