Caterpillar has announced the Motoren GmbH & Co. KG facility has received IMO III notice of compliance from the classification society DNV-GL for its M 25 E Medium-speed Marine Engine Platform.

Caterpillar Motoren GmbH & Co. KG is one of the first engine manufacturers to release an IMO III factory certified medium-speed engine group for main propulsion and auxiliary applications.


"Customers seeking an IMO III certified engine solution now have the choice to select a serialized certified engine product which guarantees safe and reliability vessel operation, while meeting the latest emission standards," said Detlef Kirste, product definition specialist for Caterpillar Marine.


The M 25 E utilizes Selective Catalyst Reduction (SCR) technology and state of the art exhaust gas temperature management. SCR works by injecting urea into the exhaust stream; a catalyst helps convert nitrogen oxide into harmless diatomic nitrogen carbon dioxide and water vapor.


The Cat SCR technology is a closed-loop system that senses required NOx reduction, adjusting the amount of urea injected appropriately. "This closed looped control, along with advanced engine combustion calibration, ensures exhaust gas temperatures are intolerance for the SCR catalyst and for cost-efficient SCR operation," said Kirste. "This eliminates the risk of catalyst damage that could occur from too high and too low exhaust gas temperatures as well as urea overdosing, seen in many of today's installations." The engine also utilizes an optimized charge air system for increased back pressure capability allowing for a much smaller SCR system.


Caterpillar's SCR technology minimizes total cost of ownership by cutting the diesel and urea expenses by offering the lowest total fluid consumption. "Our SCR systems are constantly monitored and require minimal routine maintenance, and most importantly, lifetime is aligned to meet or exceed engine overhaul intervals," said Kirste.


The system approach of SCR technology with the engine control and monitoring system linked together, make the M 25 E unique in the 1.8 - 3.15 MW medium-speed marine engine power range. Scheme A pre-certified M 25 E engines can be installed and commissioned without onboard emission verification tests. This allows the shipyard to avoid testing and certification related costs and to plan for shortest commissioning times.


The MaK M 25 E engine will be delivered with factory EIAPP certification and backed by the worldwide Cat dealer network with trained technicians to ensure service support is never out of reach.
