MTEE unveils Tier III engine after-treatment
The new solution combines MTEE’s mechanical engines with a certified selective catalytic reduction (SCR) system which has been fully optimised and tested against cost-efficiency and quality requirements.
“With this new solution we can offer our customers a cleaner auxiliary generator and propulsion system, compliant with the latest regulations and according to Mitsubishi standards,” said Ron Slenders, MTEE’s product manager for marine.
The first IMO Tier III certified product to be released with an after-treatment system is the S12R-MPTAW, a 12-cylinder auxiliary engine that is used in a wide range of marine applications such as ferries and tankers. The engine has an output of 1120 kW at 1500 rpm and 1154 and 1270 kW at 1800 rpm and is also available as a Mitsubishi Generator Set for marine. The next model that is now being tested and developed is the S12A2-MPTAW for propulsion (727 to 818 kW) and auxiliary generator (709 to 828 kW) application.
In addition to the IMO tests and certification, in-house testing has taken place to guarantee the quality of the engine and after-treatment system. The urea use is balanced for the exhaust gas to meet the IMO Tier III regulations, limit the ammonia slip and be highly cost-efficient. As the line-up is based on the IMO Tier II engines, it is possible to switch off the SCR system outside of the emission control areas to make the operations more economical.
