TE06H-16M Excavator Turbocharger Replacement ME440895 ME088840

Mounted to the engine of an excavator, the turbocharger is an air compressor actuated by exhaust gas energy. It compresses intake air using waste exhaust thermal energy to achieve more sufficient diesel combustion, which greatly raises power output, cuts fuel consumption and lessens black smoke release quantities.

Core Functions

Power Elevation PerformanceTurbocharging lifts power by 30%–50% and torque significantly on engines of equal displacement, offering superior heavyload and uphill working capability.

FuelSaving & Emission Cutback PerformanceAdequate air intake enables complete fuel combustion, reducing fuel usage by roughly 5% and minimizing black smoke, carbon monoxide and HC discharge levels.

LowSpeed Torque Optimization PerformanceGreater lowrpm torque provides higher operational force for excavator heavyload startup and digging work tasks.

Basic Structure (Three Indispensable Main Components)

Turbine End (Exhaust Side Component)Joined with the exhaust manifold assembly, it is struck by 600–900 ℃ hot exhaust gas, rotating the central main shaft at 100,000–200,000 rpm via the turbine wheel impeller.

Compressor End (Intake Side Component)Driven by the shared turbine shaft, the compressor impeller compresses air purified by the air filter unit and delivers pressurized boosted air into engine cylinders.

Central Hub Assembly (BearingCoolingLubrication Component Unit)Incorporating floating bearings and engineoil heatexchangelubrication flow passages, it tolerates extreme high temperatures and ultrahigh rotation rates. Engine oil dissipates heat to prevent bearing sintering damage problems.

Working Principle (4Phase Working Process Cycle)

Exhaust GasPowered Rotation PhaseHot highpressure engine exhaust gas enters the turbine housing and spins the turbine impeller wheel rapidly at high velocity.

Synchronous Coaxial Shaft Rotation PhaseThe turbine shaft turns the compressor wheel impeller synchronously at ultrahigh rotational speeds.

Fresh Air Compression Pressurization PhaseThe compressor inhales purified ambient filtered air and compresses it to 0.1–0.2 MPa while increasing air temperature.

Intercooling Heat Reduction PhaseHot compressed air is cooled by the intercooler device to increase air density, then enters engine cylinders for more fuel injection and greater power production output.
