MERCEDES-BENZ 3.0 OM642

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 the compression ratio is 18:1.[1] The engine features a counter-rotating balance shaft mounted between the cylinder banks to cancel the vibrations inherent to the 72 degree V6 design, and the crankpins are offset by 48 degrees to achieve even 120 degree firing intervals. 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. A particulate filter lowers soot, making this engine ULEV certified.[2][3] Engine mass is 208 kg (459 lb). Power output is 165 kW (224 PS; 221 hp) and 510 N·m (380 lb·ft) of torque.[1] For the 2007 model year, torque is raised to 540 Nm.[WIKI]
