Used volvo d12d engine

Types of used Volvo D12D engines

The Volvo D12 engine comes in different models that business buyers can choose from. The following list provides some options.

• Gen 1 (Euro 2 and Euro 3)

  The first generation of the Volvo D12 engine used a separate block casting for the cylinder head as well as a solid cast iron lower block. Its twin turbochargers were efficient, allowing the engine to produce high levels of torque at low RPM. This design was compatible with Euro 2 and Euro 3 emission standards.

• Gen 2 (Euro 4 and Euro 5)

  The second generation used a new cylinder head casting method that employed an aluminum alloy. This change reduced the engine weight. A single turbo with an integrated twin-scroll function replaced the twin turbochargers in the first generation. This provided better fuel efficiency. The direct fuel injection system boosted power output and fuel economy, and the engine achieved Euro 4 and Euro 5 emissions compliance.

• Garden variety D12D

  The used Volvo D12D engines qualified as the ''garden variety'' options. They featured a typical setup of a turbocharger and intercooler. Many truck manufacturers chose the engine model for their trucks because of its reliable performance and decent power.

• High Torque D12T

  Volvo Trucks honeycombed the D12H engine with a design to pump up the torque level to suit big haulage needs. It achieved this by using an advanced fuel injection system and a more powerful turbocharger. The new setup released higher levels of torque while maintaining fuel efficiency, making the engine perfect for long-distance transport and heavy-duty applications.

Specification and maintenance of used Volvo D12D engines

Specification

The following Volvo D12D engine specs details show its performance and what machinery it can fit in.

• General properties: This engine belongs to the Used Volvo truck engine category. Its interior design includes an in-block cast iron piston with a dry cylinder liner. The liner has a sleeve puller for easy extraction. The mileage of a new engine will be over 1 million km, but it may get up to 800 thousand km with proper maintenance.
• Power output: The power output ranges from 340 to 500 hp. Bigger trucks with higher horsepower will carry lighter, more massive cruising loads. Higher speeds are preferable in some applications, so a power output of 450-480hp is preferable for construction and high-speed uses.
• Torque: The torque is 1600-2300 Nm. A truck with 2300 Nm of torque can easily tow a trailer of up to 12000lbs, making it an excellent choice for long-distance, more massive loads.
• Displacement: The engine displacement is 12.1 liters.
• Cylinder: The Volvo D12D has a total of V-cylinders, ranging from 6 to 12. An early, basic model had only 6 cylinders. Following models have 11 to maximize power output.
• Configuration: In an engine with more than 6 cylinders, the configuration becomes more critical. The Volvo D12D has a 'V' shape. Other V engines are the D16, with a total of 16 cylinders.
• Material: Volvo manufactures its engines with high-strength aluminum and cast iron gray materials. Gray cast iron inside the block improves durability by resisting heat from the motor.

Maintenance

A used Volvo D12D engine for sale may have a lower price than new models, but its parts need constant upkeep. To make the truck run longer and at a lower cost, buyers need to schedule regular maintenance.

• Lubrication: It is vital to keep the engine working and extend its life. Lubricating oil reduces the friction between moving parts, pumps smoothly, and cools the engine.
• Belts and hoses: The engine's belts and hoses must be checked to see if they are wearing or cracking. They must be replaced if there is any sign of damage.
• Maintenance of air intake: The air intake manifold needs to be clean so fresh air can come in to mix with the fuel for combustion.
• Coolant flushing: The Volvo truck engine mustn't overheat, so the parts that remove the heat must be in good condition, too.
• Transmission fluid: It also needs to be replaced regularly to allow the engine to pull heavy loads smoothly.

Scenarios of used Volvo D12D engines

Many industries use the Volvo D12D engine model and other D12 models in various scenarios:

• Heavy-duty trucks and transport

  The used Volvo D12 truck engines are the most common ones used. They deliver good power for transporting goods and materials over long distances.

• Construction machinery

  The D12D engine power excavators, loaders, and bulldozers, among other construction machinery. These machines use the engine model to enable road building and other construction projects to go smoothly.

• Special vehicles

  Some special vehicles also use the Volvo D12D engine. Examples of these are fire trucks, refrigerated transport trucks, and motorhomes. These vehicles need an engine that offers reliable performance that is good under any road condition. The special vehicles need to ensure the safety and comfort of the passengers inside.

• Marine applications

  Fishing boats and ferries in the marine transportation industry also make use of the D12 Volvo engines. The engines provide the power needed for ferrying goods, passengers, and fishing operations over water.

How to Choose Used Volvo D12D Engines

Buying a used engine is always a daunting task. However, focusing on a few critical aspects can make the process less challenging. The first step is to determine the types of Volvo D12 engines available for the specific application. Users must select Volvo D12 engines with specific attributes and features based on their varied requirements. For instance, the D12C engine comes with a high-pressure common rail (HPCR) fuel system aimed at boosting fuel efficiency and reducing emissions. The choice of the engine should also go hand in hand with the kind of truck it is powered by and the intended use.

The second step is to assess the condition of the D12 engine. In this case, the phrase 'condition' may refer to both physical and operational status. Check for signs of wear and tear, such as rust, corrosion, or damage to engine components. If possible, obtain the maintenance history of the engine. An engine that has been regularly serviced and maintained is likely to be more reliable and perform better.

It is always advisable to enlist the help of a professional mechanic when purchasing a used Volvo D12 engine. A trained specialist has the experience and skills needed to examine the engine and offer valuable insights about its suitability for the intended purpose. Some manufacturers provide engine certifications to indicate that the engine is in good condition. Documents such as warranties also assure buyers of the supplier's confidence in the product. New parts are expensive, marking replacement and repair fees as risky. A warranty can help mitigate some of these costs.

Ultimately, buyers should consider reputable suppliers with a proven track record in selling used engines. For a more seamless purchase experience, buyers could ask for catalogs from potential wholesalers and suppliers and sift through them to find the best match for their needs.
