Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.

Overview

Caterpillar Motoren designed the M 32 E based on the reliable M 32 C engine series. The M 32 E will share the same footprint as the successful M 32 C. The M 32 E is the first MaK 5 MW engine in the 320 mm bore segment. The new design still supports operation at any ambient condition without load reduction.

Emissions

For IMO III emissions the MaK M 32 E is delivered with a Scheme A factory certified SCR solution and a factory EIAPP certificate, simplifying installation and commissiong work significantly. Caterpillar's SCR technology minimizes total cost of ownership by cutting the diesel and urea expenses by offering the lowest total fluid consumption at optimized engine and SCR life time.

Nodular cast-iron engine block with integrated ducts for lubricating oil and charge air.

Installation friendly, due to pumps and filters installed on the engine

M 32 E as a generator drive

The robust design and moderate speed permits unlimited, continuous operation with heavy fuel oil. Engine and electrics are tested prior to delivery.
