The beating heart of your vehicle is the engine, and without it, you can’t go anywhere. A car engine has many functions that help the car move faster and smoother. A car engine needs many things to help it run correctly. In this blog, we talk about the functions, mechanics, and methods of how an engine works.

What’s an Engine?

An engine is a complex machine made to adapt heat from boiling gas into a force turning a vehicles’ wheels—the dispersion by setting a bridging of an air gap between two electrodes by an electrical current. The process continues by flaring up a balance of petrol vapor and compressed air inside temporarily sealed holes with a set depth and containing pistons burning rapidly. The entire process makes an engine that burns fuel within itself as a way of developing power. The mixture is consumed, providing the ability to drive the car.

Three Different Engine Types

            There are three different engine layouts known as in-line engine, v-8 engine, and horizontally–opposed engine. The in-line engine is the most known engine formed with four vertical cylinders bound together in a row. Cars exceeding 2,000cc capacity typically have six cylinders in a row. Next, the V-engine in some vehicles, particularly vehicles with eight or twelve cylinders, are placed across from each other at a 90-degree angle. The last type is the horizontally opposed engine where it’s an extension of the V-engine but is 180 degrees wide instead of 90 degrees. The benefits are saving the height and balance of the machine.

Parts of an Engine

            The parts of an engine are essential to make a vehicle run correctly and effortlessly. The car engine has a piston, flywheel, camshaft drive belt, sump, crankshaft, and a connecting rod. Below we are going to describe each specific part.

  1. Piston: a piston is a necessary part of an engine that converts fuel to energy to drive the car forward. It is fitted with steel rings filling any gaps.
  2. Flywheel:  a flywheel is a heavy disc attached to the end of the crankshaft to smooth out the delivery of power from individual impulses of the pistons evenly. 
  3. Camshaft Drive Belt: a toothed belt driving the rotation of the crankshaft and the camshaft opening and closing an engine’s valves simultaneously.
  4. Sump: The sump has a lubricating fluid for the engine’s moving parts. A tube from the oil pumps up the oil through a filter.
  5. Crankshaft: It transmits intensity to the road wheels through the gearbox.
  6. Connecting Rod: The connecting rod converts the pistons’ up-and-down movement into rotary motion through a treadle action.
