The D2676LF in-line 6-cylinder engines with a displacement of 12.4 liters, depending on the version, can comply with the environmental standards Euro 3, Euro 4, Euro 5. These engines operate with a common rail high pressure fuel injection system in combination with the EDC 7 electronic injection control system. (Electronic Diesel Control).
MAN engines of the D2676 series are equipped with a one-piece cylinder head with overhead camshaft (OHC – Over-Head-Camshaft). The cylinder head is made of special cast iron and has shrunken valve seat inserts and pressed-in replaceable valve guides. The valve guides on all four valves are fitted with valve stem seals. The valves are actuated via individually replaceable rocker arms on the rocker arm shafts. The engine brake on the exhaust valves (EVB – Exhaust Valve Brake) is designed as individually replaceable bridges.

The TGS and TGX models are equipped with the new D20 Common Rail / D26 Common Rail in-line six-cylinder diesel engines (R6) (engine numbers 1-3). The engines are available in the Euro 4 version with a cooled exhaust gas recirculation system and PM-Kat® catalyst, as well as in the Euro 5 version based on SCR technology (Selective Catalytic Reduction, AdBlue as an exhaust emission additive). The newly developed V8 Common Rail engine from the D28 engine family complements the TGX range program. In accordance with European regulations, the engines are equipped with an On-Board-Diagnose system, including a NOx sensor (torque reduction in the event of excess NOx emissions).
