What are the materials used in constructing diesel engine?

What materials are used to build engines?

An engine is made up mainly of various metal alloys, so the material used in the engine and its components can be recycled. The most important structural materials in 4-stroke engines are cast iron, alloy and structural steels, and aluminium alloys.

What is the material of piston?

Pistons are made from either a low carbon steels or aluminum alloys. The piston is subjected to high heat, inertia, vibration, and friction. Carbon steels minimize the effects of differential thermal expansion between the piston and cylinder walls.

What is marine diesel engine?

Marine diesel engines are very similar to the self-ignition engines in heavy-duty vehicles, but they are generally larger, more complex, and operate with higher efficiency. About 75% of all marine diesel engines are four-stroke engines; however, 75% of the installed power is produced by two-stroke engines.

What do the connecting rods in a diesel engine connect?

The connecting rod connects the piston to the crankshaft. … Some diesel engine connecting rods are drilled down the center to allow oil to travel up from the crankshaft and into the piston pin and piston for lubrication.

What are the marine diesel engine types?

Types of Marine Diesel Engines

  • Four-Stroke Cycle Engine. Medium to large merchant boats employ the four-stroke cycle diesel engine to provide middling engine speeds of 250 to 850 rpm. …
  • Two-Stroke Cycle Engine. …
