Types of automobile engine

There are various types of engines used for various purposes, mostly in the automotive section. 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 don’t even 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, an engine is explained to be a machine that converts a form of energy into mechanical energy. Vehicle engines are widely known as combustion engines or heat engines. On the types of engines, I will be discussing internal and external combustion engines. These two types of engines are classified as thermal engines.

Just as earlier said “thermal engines” required a 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 take oxygen from the atmosphere or non-airbreathing engines.

Types of engines

The followings stated below are the types of engines.

Internal combustion engines:

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

Internal combustion engine

The process of powering internal combustion engines is known as the 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 transforming into useful mechanical energy. A big IC engine can generate 109,000HP, which can power a ship that transports about 20,000 containers.

External combustion engines:

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

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

In the case of IC engines, a fluid used is a mixture of fuel and air that combust, changing its chemical composition. The fluid used in EC engines 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 show up in early 2015, after multiple news of their release. It has offered great advantages over the previous vehicle version, which include the followings:

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

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