ME088725 49185-01010 Travel Motor Gearbox Turbocharger SK200-3 6D31T Engine Excavator Parts
Fitted onto an excavator engine, the turbocharger is an exhaust powered air compressor. Its operating core is harnessing exhaust gas energy to compress intake air for more complete diesel combustion, which markedly boosts power output, lessens fuel consumption and reduces black smoke emissions.
Core Functions
Power StrengtheningFor engines with the same swept volume, turbocharging delivers a 30%–50% power increase and major torque improvement, supporting powerful heavy load and climbing performance.
Fuel Economy & Emission ReductionSufficient air intake ensures full combustion, cutting fuel burn by approximately 5% and lowering black smoke, CO and hydrocarbon pollutants.
Low End Torque EnhancementImproved low speed torque supplies greater force for excavator heavy load startup and digging activities.
Basic Structure (Three Main Assemblies)
Turbine Side (Exhaust Assembly)Linked to the exhaust manifold, it receives 600–900 ℃ high heat exhaust gas that drives the turbine impeller, spinning the main shaft at 100,000–200,000 revolutions per minute.
Compressor Side (Intake Assembly)Coaxially driven, the compressor wheel compresses air purified by the air cleaner and feeds pressurized air into engine cylinders.
Center Bearing Housing (Lubrication Cooling Unit)Designed with floating bearings and engine oil cooling lubrication ducts, it withstands extreme heat and ultrafast rotation. Engine oil removes heat to prevent bearing sintering damage.
Working Principle (4 Step Cycle)
Exhaust Gas ActivationHot high pressure engine exhaust flows into the turbine casing and rapidly rotates the turbine wheel.
Shaft Driven Coaxial SuperchargingThe turbine shaft drives the compressor impeller to rotate synchronously at high velocity.
Fresh Air CompressionThe compressor inhales filtered ambient air and compresses it to 0.1–0.2 MPa while raising air temperature.
Intercooler Heat DissipationHeated compressed air is cooled by the intercooler to increase density, then enters cylinders for extra fuel injection and higher power output.
