1 Product information ABB Turbocharging TPL..-B

2 Powerful turbochargers for peak engine performance 75 % of a diesel engine s power relies on one vital component the turbocharger. The ultimate goals of turbocharged engine development are higher power and efficiency two areas in which ABB s TPL turbochargers make a vital contribution. The TPL..-B series was developed for large, modern, low-speed 2-stroke diesel engines on ocean-going ships and in diesel power stations. Five frame sizes cover the engine output range of 3,000 to 28,000 kw per turbo charger. TPL turbochargers increase engine bmep and lower fuel consumption, while also helping customers satisfy strict environmental requirements. A simple, modular design with minimized number of parts makes the TPL..-B easy to maintain. Customers benefit from low lifecycle costs and longer times between overhauls. 2

3 Built with the user in mind The number of parts has been minimized to keep lifecycle costs low and shorten the time needed for overhauls and service. The design of the TPL..-B is fully aligned with market requirements. TPL..-B turbochargers meet customers as well as end-users need for a simpler construction with fewer parts, greater efficiency at higher pressures, and reduced engine emissions. Built to be robust and reliable, with a long operational life, TPL..-B turbo chargers have numerous innovative features that also keep them compact. Service can be carried out faster, even in confined spaces, thanks to the modular design and easy-to-handle parts. Tried and tested ABB performs a comprehensive series of qualification tests to ensure the total reliability of its turbochargers. Overall reliability of the TPL..-B is also improved by the special design of the bearing assembly and an emergency oil system that ensures safe runout of the turbo charger rotor should the lubrication system fail. Since being introduced to the market, more than 5000 TPL..-B units have been specified or put into service worldwide. 3

4 Benefits that count Simple, rugged and compact the TPL..-B is designed to keep your running costs low.

5 TPL 73 TPL 77 TPL 80 TPL 85 TPL91 Design features Turbine and compressor Compressor The compressor features a single-piece, splitter-bladed aluminium alloy wheel with backswept blades for a wide map and peak efficiencies of more than 86 %. Use of largediameter compressor wheels ensures high volume flow rates for optimized matching to the engine application. Different trims ensure that all 2-stroke market requirements are met. Example of compressor map for TPL 85-B c [-] Turbine The TPL..-B turbocharger s axial turbine is designed for the very high efficiencies and volume flow rates required by the 2-stroke diesel engine market. Featuring wide-chord blading, without lacing wire, the turbine is especially well suited for constant-pressure applications. ABB offers a range of trims covering all 2-stroke market requirements.

6 Design features Bearings and casings Bearing lifetime Benefiting from experience gained with over 50,000 ABB turbochargers with plain bearings in service worldwide, TPL plain bearings are designed to run for 36,000 hours before being changed. ABB developed the new bearing assembly for direct lubrication by the engine lube oil system. The main axial bearing consists of a free-floating thrust disc with profiles on both sides, rotating at about half the rotor speed. This ensures thick oil films, offering extra-high resistance to wear caused by contaminated oil. Disc wear is also reduced by the application of an extremely hard coating. The radial bearing bushes are fixed with screws and centered in a squeeze oil film damper.

7 Emergency lube oil system An emergency lube oil system to ensure safe runout of the turbocharger rotor if the lubrication system fails is a standard feature of the TPL..-B series. TPL 91-B and TPL 85-B turbo chargers have the emergency oil system integrated in the bearing casing for compactness and to minimize the oil flange connections. Smaller sizes have a tank mounted on top of the bearing casing. The system works by gravity and requires no auxiliaries. Optimized casing design TPL..-B casings are optimized for applications on 2-stroke engines. Excellent flow dynamics and minimized thermal stress are ensured. Features include an integrated turbine washing device and temperature and pressure measurement. Casings are insulated to keep surface temperatures and noise levels as low as possible. 7
