Review MERCEDES benz Cdi Diesel 3.0l Complete Engine Motor Block Assembly fits W211 E320 2007–2009

The Mercedes-Benz W211 E320 CDI is a diesel-powered executive car that was produced from 2001 to 2009. At the heart of this model is the 6420105445 07-09 3.0L engine, which is characterized by its advanced motor block design.

The motor block is the foundation of the engine, providing a strong and rigid structure to house the cylinders and other engine components. In the case of the Mercedes-Benz 3.0L diesel engine, the motor block is made of high-strength aluminum alloy, which offers excellent heat dissipation properties and reduces the overall weight of the engine.

This motor block is a SOHC (Single Overhead Camshaft) design, which means that the camshaft is located above the cylinder bank and acts upon the intake valves directly. The engine features a common rail system with a maximum injection pressure of 1600 bar, which ensures efficient fuel combustion and low emissions.

The cylinder bore measurement of this engine is 82.6 mm, and the stroke length is 92.2 mm, resulting in a total displacement of 2926cc. The engine produces a maximum power output of 170 kW (228 hp) at 3800 rpm, and maximum torque of 440 Nm between 1600 and 2400 rpm.

The motor block is also equipped with advanced features such as a cast iron cylinder liner, which provides excellent durability and reduces wear and tear. The engine block also has a water jacket that surrounds the cylinders to facilitate efficient cooling.

Another key feature of this motor block is its compact design, which allows for better packaging and easier installation into the vehicle. The engine block also features a number of mounting points for various engine accessories, such as the alternator, power steering pump, and air conditioning compressor.

Overall, the Mercedes-Benz 6420105445 07-09 3.0L engine motor block is a high-performing and durable component that forms the core of the W211 E320 CDI diesel engine. Its advanced design, efficient fuel combustion, and low emissions make it a popular choice among Mercedes-Benz enthusiasts and executive car buyers.

The Mercedes-Benz W211 E320 CDI with a 3.0L diesel engine and motor block number 642.010.54.45 (07-09 production) is a popular choice among car enthusiasts and those in the market for a reliable and efficient vehicle. Here are some pros and cons associated with purchasing this engine:
