The upcoming emission legislation IMO Tier 2 and IMO Tier 3 require a further step in technology for inside the engine technologies. These will be of major interest for customers as Emission Control Areas (ECAs), state or port authorities may drive towards implementation of emissions reduction solutions from a financial perspective. The pay back time for the customer after implementation can be extremely short. Caterpillar Motoren GmbH & Co. KG has developed or is on the way to develop those solutions. One of the tasks was and still is to develop these solutions to be retrofittable. In former presentations Caterpillar had announced that the pure IMO Tier 2 technology including higher compression ratio, flex cam technology (FCT), updated valve and injection lopes and turbo specification can be retrofitted on MaK C- engines. This was proven by a field test which was successfully carried out on a vessel called 'Fure West' in October 2007 which is in operation since then meeting IMO Tier 2 legislation. Similar development was done to the Caterpillar Common Rail System (CCR). MaK C-engines after production date 2005 are prepared such that the conventional injection system and controls can be dismantled and replaced by a set of components for Common Rail. There is also one field test engine in successful operation since May 2008. Caterpillar Motoren is now on the way to develop a dual fuel solution for the M43 in the first step. It is planned here as well to have a design and technology to retrofit and take conventional components off and replace them by dual fuel equipment. In all these cases it is self explanatory that these solutions will be Marine Society approved. Todays MaK engines offer the opportunity to react on future emissions legislation of all kinds and are therefore a viable, environmental positive and future orientated solution for customers in the Marine and Electric Power business.
