MAN Diesel & Turbo is introducing the MAN EcoCam as a retrofit solution for the low-load optimisation of its low-speed, mechanical engines with single turbochargers. The EcoCam offers significant fuel savings of 2 - 5 g/kW – with short payback times – and delivers an increased Pmax cylinder pressure through the adjustable exhaust-valve timing, the company said in its press release.
Christian Ludwig – Head of Retrofit & Upgrade – MAN Diesel & Turbo, said: “Slow-steaming is now an established industry standard across all segments, including the tanker and bulker markets, and MAN Diesel & Turbo continuously seeks to further refine its technology and improve efficiency. The MAN EcoCam adjusts the exhaust-valve timing between 10 and 60% load, giving a 2 - 5 g/kW fuel saving with minimal to no interruption to a vessel's schedule during installation.”
He concluded: “The MAN EcoCam has been thoroughly tested and we are happy that we are now able to provide our customers with a low-load tuning method for mechanically controlled engines with a single turbocharger.”
MAN Diesel & Turbo is initially rolling out the MAN EcoCam to a number of its MAN B&W S50MC-C engines, and will eventually introduce it stepwise to its mid- and large-bore engine programme.
