The Mercedes-Benz OM642 engine is a 3.0 Liter, 72° 24-valve, aluminum block diesel V6 engine manufactured by the Mercedes-Benz division of Daimler AG as a replacement for the Mercedes-Benz inline-5 and -6 engines[1].
The engine features common rail fuel injection and a variable nozzle turbocharger. The injection system operates at 1,600 bar (23,000 psi), while intake air is compressed at a ratio of 18:1[1]. In some heavy vehicle applications, Mercedes' BlueTec AdBlue urea injection is utilised for NOx reduction[2]. In lighter vehicle applications, a NOx storage catalyst captures Nitrous Oxides which are periodically purged (decomposed) by running the engine slightly rich for a little while. A particulate filter lowers soot, making this engine ULEV certified.[2][3] Engine mass is 208 kg (460 lb). Power output is 165 kW (224 PS; 221 hp) and 510 N·m (380 lb·ft) of torque[1].
The engine is manufactured at the Daimler AG plant in Marienfelde, Berlin, Germany[4]
Oil specification MB 229.51 or MB 228.31 is recommended[citation needed].
