Components Complete The Design Of Diesel Engine

There is a list of components that diesel engine parts manufacturers produce to complete the design of diesel engine. The compression system has the parts that develop engine compression and let the heat energy move inside the burning air-fuel mixture to transform into mechanical energy. In this post, we will discuss about these parts in detail.


  • Engine block –

    Engine block is the basic support and connecting point for all other engine parts. Manufacturers produce engine blocks by pouring molten cast iron, steel, or aluminium into the molds. They wait until the metal cools down. They wash out the molding sand and machine the block in order to install other parts. Major parts installed on the block are the crankshaft, pistons, cylinder heads, camshaft, and manifolds.

  • Pistons –

    it transfers the force of expanding combustion gases to the adjacent rods. Pistons are manufactured with aluminium for lightweight construction. Mostly manufacturers design automotive pistons with two compression rings and one oil ring. Compression rings are installed at the top of the piston.

  • Crankshaft and connecting rods-

    Manufacturers use forged steel to make connecting rods, which are used to connect the piston to the crankshaft. Each connecting rod is connected to a piston through piston pin. The manufacturers design the crankshaft in such way that it rotates inside of the bearings with least friction.

  • Cylinder heads –

    It includes a combustion chamber for each cylinder and creates the top of the cylinder. Cylinder heads have the intake and exhaust valves and sometimes lifters and camshaft as well. Manufacturers design cylinder heads with cast iron or aluminium.

  • Push rods-

    these components are used on cam-in-block engines only. They convey the lifter motion to the rocker arm. Most of the push rods are hollow.

  • Vibration damper-

    When the engine cylinders ignite, the force is conveyed to the crankshaft. When such force hits the vibration damper, part of the crankshaft rotates before the rest of the crankshaft. This results in crankshaft twisting. When the force is removed, the partially twisted shaft unwinds and such action results in torsional vibration.

  • Cooling system –

    Cooling system includes various components that expel unwanted engine heat and regulate engine temperature. Cooling system is required because it is not possible to eliminate all of the heat created by combustion.

You can replace or restore these components with the help of experts. Diesel engine parts manufacturers are offering maintenance and cleaning services for diesel engine oil to their customers.
