Our two-stroke turbocharging propulsion booster

TPL-B Our two-stroke turbocharging propulsion booster Powerful turbochargers for peakengine performance 75 percent of a diesel engine’s power relies on one vital component – the turbocharger. 01 MSC Methoni with TPL85-B turbochargers The ultimate goals of turbocharged engine development are higher power and efficiency – two areas in which Accelleron’s TPL turbochargers make a vital contribution. The TPL-B series was developed for large, modern, low-speed twostroke diesel engines on ocean-going ships and in diesel power stations. Five frame sizes cover the engine output range of 3,000 to...

TPL-B Our two-stroke turbocharging propulsion booster 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. 02 TPL-B – simple, modular design 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 turbochargers have numerous innovative...

TPL-B Our two-stroke turbocharging propulsion booster Design features Turbine and compressor 02 Turbine The TPL-B turbocharger’s axial turbine is designed for the very high efficiencies and volume flow rates required by the two-stroke diesel engine market. Featuring wide chord blading, without lacing wire, the turbine is especially well suited for constant pressure applications. Accelleron offers a range of trims covering all two-stroke market requirements. Compressor The compressor features a single piece, splitter-bladed aluminum alloy wheel with backswept blades for a wide map and peak...

TPL-B Our two-stroke turbocharging propulsion booster Design features Bearings and casings 01 TPL plain bearings are designed to run for up to 36,000 hours Bearing lifetime Benefiting from experience gained with plain bearings in service worldwide, TPL plain bearings are designed to run for 36,000 hours before being changed. Accelleron developed the new bearing assembly for direct lubrication by the engine lube oil system. The main axial bearing consists of a free-floating thrust disk with profiles on both sides, rotating at about half the rotor speed. This ensures thick oil films, offering...

TPL-B Our two-stroke turbocharging propulsion booster 02 TPL-B casings are optimized for applications on two-stroke engines 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 turbochargers 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...
