Product Description

T- ABB Turbo Seals T- A170 Air Sealing Bush For Marine Engine Parts


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

T- A170 turbocharger air sealing bush belongs to one part of T- ABB / T- A100-L series turbocharger, which is high efficiency single-stage turbocharger for two-stroke diesel engines. It's designed to give operators of low-speed two-stroke marine engines market leading levels of performance, emissions compliance, application flexibility, total cost of ownership and operational safety. It's widely applied in low-speed tow-stroke marine engines, and also some industrial engines.

  • High efficiency;
  • High pressure ratios: the 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 A100-L series turbocharger make the easy maintenance and overhaul possble.

T- A100-L type turbocharger includes:

T- ABB T- A100-L type
T- A165-L
T- A170-L
T- A175-L
T- A180-L

T- A170 Air Sealing Bush Function:

The sealing devices of the exhaust gas turbocharger is divided into two types: gas seal and oil seal. The T- A170 air sealing bush belongs to gas seal. 

The function of the gas seal is to prevent leakage of compressed air at the compressor end and gas exhaust gas at the turbine end. A large amount of leakage of compressed air at the compressor end will reduce the boosting efficiency; leakage of the exhaust gas at the turbine end will cause the turbine power to drop, and high temperature gas leaking into the bearing housing will contaminate the lubricating oil and damage the bearing.
