Different Types of Used Car Engines

The engine is considered to be the most important part of a vehicle. The initial car models had steam-powered engines, but over time there had been enough technological advancements that have taken place to produce better, more fuel-efficient engines. Nowadays, there are many different types of used engines and motors for sale to choose from based on what kind of environment they’re meant for. There are different alternatives too, like electric and hybrid vehicles powered by batteries or gasoline-electric combos.

  1. The Straight 4

The straight-four has been around for a long time and remains popular today because it’s very simple and easy to tune. It has an even number of cylinders that are arranged in a straight line. The difference in power between this engine with two valves per cylinder and the one with three is negligible, so the latter is less common. This engine type can be found all across Europe, Asia and America, while internal combustion used engines for sale are the most common type of car engines worldwide.

  1. The Straight 6 or V6

This type is rather similar to the first one, but it’s longer and wider due to its added cylinders. It’s perhaps more suitable for bigger vehicles, but some sports cars can benefit from the additional power as well. There are many different types of V6 engines for sale, and one of the most popular ones is the 60-degree unit with three banks of two cylinders each. This engine type has been around for a long time, but it’s still very popular today.

  1. The Straight 8

This type is longer and wider than a V8 engine because it has an extra cylinder bank. It has mostly been used in commercial vehicles like trucks back in the day, but nowadays it’s common to see some luxury vehicles with this type of engine as well.

  1. The Straight 6 or I6

This type of engine has also been around for a long time and is often seen in cars like the Honda Civic. It has six cylinders and has an even number of valves that pump into each cylinder by way of a short rocker arm. This type is fairly small, but it looks very nice on high-end vehicles like luxury cars and sports cars. Some even go as far as to say that this engine has fewer parts than most others, making them more environmentally friendly because they require less maintenance over time. 

  1. The V12

This kind of engine has a bank made up of three rows arranged in two banks of six cylinders each. They have a big displacement and are extremely powerful, meaning that these cars can go fast. They aren’t the most fuel-efficient type, but some makers have found ways to lessen this problem. This engine is used a lot in commercial vehicles like trucks because it has a high thermal capacity and can be modified to use diesel fuel or gasoline depending on the need of the driver.

  1. The V8 or Octo-coupe

This kind is also very powerful due to longer strokes and rods coupled with its eight cylinders arranged in two banks. It’s more suitable for commercial vehicles than sports cars because of its power. The engines are often found in luxury SUVs, but their design is fairly common, and you can find them on the back of the Ford F-150 pickup truck, which features two V8s side by side.

  1. 7. The 4-cylinder or I4

This type has four pistons, so it’s often referred to as an I4 because it has four cylinders. This means that there are always four valves that open and close on each cylinder to allow air and fuel into the combustion chamber.


So, these were the top types of car engines for sale. Some are more fuel-efficient than others, and in some cases, bigger is better. The straight four has been around for a long time and remains popular because it’s easy to tune for more power over a short period of time. The V12 is the most powerful engine and the one that most luxury vehicles use, but the straight-six or I6 can still be found in some modern vehicles. Make sure to buy used engines with warranty for cost-effectiveness.
