Hatz Diesel, a German manufacturer of small industrial diesel engines, is planning to present a concept study of the new 4H50TIC as a marine version at the SMM exhibition in Hamburg.

The engine has been manufactured in series production since the beginning of 2014 and is designed primarily for use in construction machinery, as well as for stationary and mobile applications.

For use as a marine propulsion engine, keel cooling has been adopted for the required engine cooling and to reduce heat radiation, insulation was installed for the exhaust silencer. Besides this, the 4H50TIC marine includes the same characteristics as the base engine. The 55 kW water-cooled 2-litre 4-cylinder turbo engine is equipped with a Bosch common rail system with 1800 bar rail pressure.

According to Hatz, the engine sets new standards in its class in terms of power to weight ratio, size and fuel efficiency. Weighing only 173 kg the engine is about 90 kg lighter and correspondingly smaller than its nearest competitor, which leads to lower energy consumption in the production process. Besides this good power to weight ratio, the engine underlines its ecological characteristics by a low specific fuel consumption of just 205 g / kWh at the best point.

In addition, the consumption is not more than 240 g / kWh in a very broad speed and load range which reflects a realistic driving cycle. Also in terms of exhaust emissions, the engine sets standards. In the off-highway sector the engine achieves easily the EU 97/68 Stage IIIB and the U.S. EPA Tier 4 exhaust emission levels, both of which are more stringent in regard to the limits as the emission regulations in maritime applications.

In addition to the 4H50TIC marine two other maritime Hatz products will be introduced. A 1B50 with a maximum power of 8.5 kW, including transmission, which in particular is aimed at commercial and non-commercial fishing, as well as a 2M41 engine, which is constructed and certified according to GL specifications.
