Hatz Diesel has introduced the first engine of a newly developed water-cooled engine series: a 2-L diesel engine equipped with a Bosch common-rail injection system with 1800 bar (26.1 ksi), turbocharger, and external exhaust gas recirculation (EGR). The 4H50TIC engine, which is expected to launch in spring 2014, achieves a maximum output of 55 kW (74 hp) and weighs 173 kg (381 lb). The engine is equipped with two valves per cylinder and meets 97/68/EC Stage IIIB and EPA Tier 4 Final without a particulate filter. The engine crankcase is made of a thin-wall cast iron, the cylinder head and valve cover made of cast aluminum, and the oil sump of steel. The new 4H50TIC engine has a specific fuel consumption of 210 g/kW·h (0.35 lb/hp·h) at its best point. A service interval of 500 h is achieved due to a hydraulic valve adjustment and well-dimensioned fuel filter.

AKG of America’s research and development center at its Mebane, North Carolina, facility hosted a grand opening in February that features a new water/glycol thermal shock test stand for product validation.
Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
