What is a 4-Cylinder Engine

The amount of cylinders in an engine corresponds to the number of pistons within the engine. Inside the cylinders of the engine, pistons appear to move up and down. These operate by opening and closing air intake valves, allowing air and fuel to mix.

Generally, the pistons, like most 4-cylinder engines, are in a vertically, single-direction layout. While in a 6-cylinder engine, the pistons are normally inclined, with two banks of three cylinders creating a V shape. This form is said to be more sleek and strong.

In addition, these “V6” engines are often softer than 4-cylinder engines. The pistons of 4-cylinder engines, particularly in bigger engines, are extremely loud.

Modern four-cylinder engines are built to be as powerful as possible. Consequently, a 4-cylinder engine built with technical advancements is significantly more powerful than a 4-cylinder engine built years before.
