T- ABB Turbocharger / T- A170-L Bearing Pedestals For Low Speed Diesel Marine Engines

T- ABB Turbocharger / T- A170-L Bearing Pedestals For Low Speed Diesel Marine Engines

T- ABB / T- A100-L series marine turbocharger features:

T- A170-L turbocharger bearing pedestals belong to T- ABB / T- A100-L series marine turbocharger and its design features are as below:

• High efficiency;
• High pressure ratios: the T- A100-L is capable of delivering pressure ratios up to 5.0 combined with a high specific air volume flow.
• Low noise: the air outlet silencer is integrated in the compressor casing for very effective noise reduction;
• Step up performance with High Pressure Tuning (HPT): 1. Higher peak firing pressures at low and part load achieved by an increase in the engine’s scavenging air pressure;  2. No excessive firing at full load thanks to an electronic management system that varies compression ratio in each cylinder by controlling the timing of the exhaust valves; 3. Lower fuel consumption of up to 5 g /kWh;  4. HPT saves money for engine builders, ship owners and operators:
• Good design and inherent simplicity of the T- A100-L series turbocharger make the easy maintenance and overhaul possble.

T- A170-L turbocharger bearing pedestals description:

The turbocharger casing includes turbine part, bearing part and compressor part, so the turbine housing, bearing pedestal and compressor housings cover and protect all the important parts safely in the turbocharger to ensure a premium performance of the engine.

The turbine casing, bearing pedestal and compressor housing are made by cast iron. Some casings are water cooled which complicates the casting.
