NEW: diesel engine by MAN Engines - A Division of MAN Truck & Bus

MAN extends its power range for heavy duty operations. The so far strongest MAN engines for commercial applications (D2862 LE431 and D2842 Le421 with 662 kW / 900 hp) are being replaced. The D2862 LE44x is now taking the lead, with a performance of up to 735kW (1,000 hp).

The V twelve cylinder engine is available in two versions: the D2862 LE441 for the emission standard IMO Tier 2 and the D2862 LE444 which fulfills EPA Tier 3 commercial. By adapting the turbocharger and the valve timing, MAN was able to raise the mean pressure and increase the power rating by 73 kW (100 hp) compared to the most powerful engines available until now.

The new, efficient MAN marine engine D2862 LE44x, with its increased power and a dry weight of 2,270 kg, offers an excellent power density for heavy-duty applications such as tugboats and freighters. With a capacity of 24.24 l, a bore of 128 mm and a stroke of 157 mm, the powerful MAN marine engine can achieve a maximum torque of 4,380 Nm at 1,100 to 1,600 rpm.

The MAN D2862 LE441 proves particularly efficient if the costs over its entire life cycle are taken into account: even with a specific consumption under full load at maximum torque, the 12-cylinder engine has an out- standing minimum consumption of 192.3 g/kWh.

Furthermore, it features oil change intervals of 600 hours and average overhaul intervals of 18,000 operating hours. Individually mounted cylinder heads also ensure ease of service, which allows MAN's solid power unit to shine when it comes to cost-effectiveness calculations.
