Connect with Southwest Engines to keep your vehicle’s functioning smooth

The main source of power in the vehicle is the engine. To generate mechanical power, the engine utilizes fuel and burns it. The heat which is produced by the combustion is used to make pressure which is then utilized to drive a mechanical device. In this post, we will know about the differences between different types of engines.

Internal vs. External

Before the 20th century, the combustion or burning of the fuel happened outside of the real engine. The fuel, mostly coal, was burned for generating heat. By using this heat, the water is boiled to produce steam. The steam was put under pressure and then entered into the engine where it enforced the piston down in the cylinder. This is traditionally known as a steam engine or called as an External Combustion Engine.

Today’s modern vehicles are available with an engine in which fuel is burned inside and it is referred to as an Internal Combustion Engine. With the burning of air/fuel mixture, it expands quickly and results in the increase of pressure inside the cylinder. This increased pressure enforces the pistons down the cylinder and therefore drive the connecting rod to turn a crankshaft that delivers a continuous rotating motion for driving vehicles and its components.

Reciprocating vs. Rotary

Both the internal and external combustion engine utilizes a piston enclosed in a cylinder which is connected first to a connecting rod and then to a crankshaft. Due to the force of piston, the cylinder gets down which provides a push to the connecting rod that ultimately turns on the crankshaft. This type of engine is known as a reciprocating engine because of the movement of pistons in up and down direction.

In opposite to this engine is the rotary engine which utilizes a rotor that is in a triangular shape. The rotor is housed in a chamber of elliptical shape and attached to the crankshaft. With the movement of the rotor around the chamber, it draws an air/fuel mixture, compresses it, blisters and after that ejects it. Due to the movement of the rotor, the rotation of the main shaft occurs.

Gasoline vs. Diesel

At the present time, the most popular fuel gasoline is in more use. However, in industrial vehicles and machinery, diesel fuel has been used for many years and is starting to get popularity in passenger cars. In comparison to gasoline, diesel fuel has more heat energy that makes it more economical. But it is heavier, thicker and does not vaporize in an easy manner as gasoline and must be utilized in engines that have high pressure. Due to this reason, the fuel must be squirted straightly into the cylinder. At the end of the compression stroke, the fuel is introduced into the cylinder and burns under the heat of compression that eliminates the requirement for an ignition system.

Irrespective of the engine that your vehicle comprises, you should take care that it is working properly. A single issue for a long time can damage your engine completely. Well, if any such kind of problem arises, it is best to look for Southwest Engines or SWEngines for buying used engines which will keep your vehicle functioning proper.
