Types of automobile engine

 

Today in our daily life we move from one place to another by the means of transportation, most especially vehicle and other means you may know. For those commercial users of vehicles just imagine like 85% of them do know the type of engine their vehicle carries. if you’re one of them you need to learn and for an automobile engineer who wants to know, you’re in the right place. Previously, an article was published titled “understanding an automobile engine“. check out!

Types of automobile engine

In this precious article, engine is explained to be a machine that convert a form of energy into mechanical energy. An automobile engines is widely known as combustion engines or heat engines. On the types of automobile engine, I will be discussing on internal and external combustion engines. They are classified as thermal engines.

Just as earlier said “thermal engines” required source of heat to convert into mechanical energy. It could be through combustion (small controlled explosion in the chamber) or no combustion. These engines can also be airbreathing engines. that is, they takes oxygen from the atmosphere or non-airbreathing engines.

The followings stated below are the types of car engines.

Internal combustion engines: just as the name implies, internal combustion engine is types of automobile engine that allows fuel combustion to occurs inside the engine, using produced pressure to cause temperature to rise. it is a mixture of fuel and air igniting in the various chamber in the engine. This process happens thousands of time in a minute, giving the vehicle its movement. These types engine is abbreviated as IC engine.

Internal combustion engine

The process powering internal combustion engine is known as combustion cycle, in most engines it is called four stroke or cycle, hence it is named four stroke engine. IC engines are differentiated by their number of strokes or cycles piston makes for full rotation of the crankshaft. The four stroke steps include;

  • Intake
  • Compression
  • Ignition
  • Exhaust

Hence, having the sense of how chemical energy is being transform into useful mechanical energy. A big IC engine can generate 109,000HP, which can power a ship that transport about 20,000 containers.

External combustion engines: external combustion engines is a type of heat engine that also burns fuel. But in this situation it keeps the fuel and exhaust products separately. That is, fuel is burn is a chamber and the working fluid is heated inside the engine through a heat exchanger.

The EC engines functions similarly to that of IC but have some differences as well. These two types of engines required heat, which is obtained when a source undergo thermal dilation-contraction or a shift in phase without changing its chemical composition.

In the case of IC engines, fluid used is a mixture of fuel and air that combust, changing its chemical composition. The fluid used in EC engine can be either gaseous (Stirling engine), liquid ( Organic Rankine cycle engine), or change of phase (steam engine) all these are examples of EC engines.

Electric Engine: electric cars shows up in the early 2015, after multiple news of its release. It has offers great advantages over previous vehicle version, which include the followings:

  • Less pollution than gasoline powered engine, making it environmentally friendly
  • It is powered by electric motor and required battery and charging.

Advancement in technology today has brought a great change in an automobile engine. The fluids (petrol or diesel fuel) serves as cleaning agent to the fuel system, improving the performance of the engine and reducing emissions not for movement.
