Increased Power Rating For Marine Diesel Engine
Caterpillar’s M 32 E to serve offshore market in diesel electric and auxiliary applications with multi-engine concepts
Caterpillar Marine Power Systems has announced the development of the MaK M 32 E, which the company said is a high-performance marine diesel engine platform for the commercial marine industry based on the M 32 C engine series.
The M 32 E engine boasts an increased power rating of 550 kW per cylinder: at 720 r/min the total power output is 3300 kW for the six cylinder configuration, and the nine cylinder configuration can produce a total power output of 4950 kW at 750 r/min.
The company said the engine features a stroke of 460 mm and utilizes the piston and other proven components from the VM 32 C, as well as the same footprint as the M 32 C. In addition to having heavy fuel oil (HFO) capability, the new M 32 E features the same lube oil consumption and maintenance intervals as the M 32 C product series. The engine is EPA Tier 2 and IMO 2 compliant.
Cat said the higher power output is ideal for the offshore market in diesel electric and auxiliary applications with multi-engine concepts. The M 32 E is also a suitable platform to drive variable speed diesel-electric systems and can be integrated with Cat high-speed engines in mixed engine rooms, the company said.
The first engine deliveries are anticipated for the fall of 2014.
