NEW Engine 2005 Mercedes E-420 4.0CDI V8 260 Hp OM628-910 Engine 2005 Mercedes E-420 4.0CDI V8 260 Hp OM628-910 (628.910 50 345678 ).The OM628 engine was Mercedes-Benz’s first V8 diesel with twin-turbocharging and common rail injection, offering a level of torque and refinement that was ahead of its time. It was originally developed for large luxury cars like the E-Class W211, S-Class W220, and G-Class W463. Even today, a well-maintained OM628 delivers strong performance, smoothness, and remarkable fuel economy for a V8. ⚙️ Key Features Twin-Turbochargers:This engine uses two small turbos instead of one large one, providing faster boost (better throttle response) and very strong torque from low RPM. Common Rail Direct Injection:The OM628 was among the first V8 diesels to use Bosch’s second-generation common rail, allowing very high fuel pressure (~1,350 bar) for precise, efficient combustion. Durability:Designed to last well over 400,000 km (250,000 miles) with proper maintenance (oil changes every 10,000-15,000 km, good diesel quality, etc.). Power Delivery:Massive torque at low revs, making it very smooth and powerful, ideal for highway cruising and heavy acceleration. Cooling System:Sophisticated water-cooled system with an extra oil cooler and turbo intercoolers to manage the engine’s high thermal load.   �� Performance Very strong low-end torque — maximum pulling power available at only ~1,800 rpm. Smooth V8 performance; less vibration compared to inline diesels. Tuned for durability and long-distance cruising — often used in high-mileage taxis and armored vehicles.   �� OM628.910 Engine Overview Category Detail Engine Code OM628.910 Engine Serial Number 628.910 50 345678 (specific to your engine) Vehicle Model Mercedes-Benz E-Class (W211) E 420 CDI Production Years 2005 Displacement 3,996 cc (4.0 liters) Fuel Type Diesel (ULSD recommended) Power Output 260 hp (191 kW) at 3,600 rpm Torque 560 Nm (413 lb-ft) at 1,800–2,600 rpm Turbocharging Twin-Turbo (Bi-Turbo system) Injection Type Bosch Second-Generation Common Rail Compression Ratio 18.5:1 Cylinders / Valves V8 / 32 valves (4 valves per cylinder) Materials Cast Iron Block / Aluminum Alloy Heads Timing System Chain-driven (no timing belt) Emission Norm Euro 3 Weight ~265–275 kg (dry) Engine-code OM629-910 Car brand Mercedes Model E-420 CDI IN ( 628.910 50 345678 ) Condition New Mileage 0 km Warranty 24 months
