4 Stroke Inline Engine

Inline engines, featuring all cylinders aligned in one row without offset, provide a simplified construction process compared to other configurations. Found in four, six, and eight-cylinder arrangements, these engines have been utilized in automobiles, locomotives, and aircraft. Notably, the term "inline" is broader in aviation contexts, as seen with inline engine (aviation). Inline engines boast easier manufacturing due to their single metal casting for both cylinder bank and crankshaft, requiring fewer cylinder heads and camshafts. They also possess smaller overall dimensions compared to alternatives like radial designs and can be mounted in any direction. Straight configurations are less complex than V-shaped counterparts, with a support bearing between each piston versus every two in "flat and V" engines. While six-cylinder variants exhibit balance, four-cylinder models can be inherently rough due to their off-balance nature, unlike 90-degree V fours or horizontally opposed 'boxer' four cylinders.
