inline-four

Four pistons, one row

An inline-four is a four-cylinder internal combustion engine with all cylinders arranged in a single row.

This configuration dominates small to mid-sized cars and motorcycles due to its compact size, simplicity, and smooth operation.

The Civic comes with a 2.0-liter inline-four.

Also called a straight-four.
