Due to its special shape, the cylinder head is referred to by the manufacturer as a delta cylinder head . The multi-hole injection nozzles are arranged centrally in the combustion chamber.An injection high-pressure pump with a maximum of 250 bar is used.

The engine has an exhaust gas turbocharger with an electric bypass valve actuator .Behind the turbine of the turbocharger first a three-way catalyst is used. The engine has a particulate filter as standard .
