The Chevrolet Inline-4 engine one of Chevrolet's first automobile engines was designed by Arthur Mason and introduced in 1913. Exposed pushrods actuated valves in the detachable crossflow cylinder head. Chevrolet referred to its overhead-valve engine as a "valve-in-head" design. This drew considerable publicity in a time when most rivals were flatheads. It was produced in a single size through 1928 when it was replaced by the Chevrolet Straight-6 engine.

Chevrolet later used many other straight-4 engines, including the straight-6-derived 153 and other more modern engines documented in the list of GM engines.

171

The 171-cubic-inch (2.8 L) was the sole member of this family. It featured splash lubrication. For 1916 a simplified variant of the 171-cubic-inch four-cylinder engine from the Series H yielded 20 horsepower (same as the Ford's T). For its last year (1928) it gained a revised carburetor, higher compression, aluminum pistons, and larger valves a for a rating of 35 horsepower at 2,200 rpm. Because of increased weight of the slightly longer 1928 Chevrolet National Series AB performance failed to improve from the 1927 Chevrolet Series AA Capitol.
