D6d
Volvo

The Volvo D6D is a robust and efficient 6-cylinder, in-line, 4-stroke diesel engine renowned for its exceptional durability, reliable power, and superior fuel economy . With a 5.7-liter displacement and feturing turbocharged and intercooled aspiration , this water-cooled engine is engineered to deliver consistent performance in the most demanding construction and industrial environments . Its proven technology and robust construction make it a trusted power source for a wide range of heavy machinery .
For a quick overview, here are the core specifications of the D6D engine:
The Volvo D6D engine is built to be a dependable power source for various types of heavy equipment, primarily in Volvo's construction machinery lineup :
Excavators: It is a key power source for mid-sized Volvo excavators, including the EC140B, EC160B, and EC210B models .
Other Equipment: The engine's reliable design also makes it suitable for wheel loaders and graders .
Robust Engine Design for Longevity: Built for maximum durability, the engine features a strong cast-iron block and cylinder head along with wet cylinder liners, which not only withstand extreme operating conditions but also simplify overhaul and maintenance processes .
Turbocharged and Intercooled Aspiration: The turbocharging system forces more air into the cylinders, significantly boosting power output and torque. The aftercooler reduces the intake air temperature, increasing its density for more efficient combustion and improved overall performance .
Mechanical and Electronic Fuel Injection: Depending on the variant, the D6D utilizes either a mechanical injection system or an Electronic Unit Injection (EUI) system . This technology ensures reliable fuel delivery and good combustion efficiency.
Ease of Maintenance and Repair: The D6D is designed with serviceability in mind. Its less complex electronic systems compared to newer engines make it well-suited for repairs in the field with basic tools, helping to reduce downtime and lower repair costs .
