These ECUS control OM651 Diesel motors, produced from 2008 to 2020, initially produced to satisfy and anticipate the Euro 5 anti-pollution standards and to be ready for the Euro 6 standards.
We are talking about turbodiesel four-cylinder motors with third generation common rail technology. These motors have avant-garde solutions, like piezo-electric injectors, used until then only on a few other thrusters in the world. This technology allows an accurate and particularly fast Diesel dosage. This allows less waste, as well as lower carbon footprint.
Beside the 2.2L, the OM651 motor has been produced between the years 2011 and 2014, an 1.8L motor in two versions of power, respectively 80kW in the limited version, and 100k on the one at full power. From 2014 the motor was no longer produced, to leave space totally to the 2.2L version.
