What is a h type engine?

An H-type engine, also known as a flat engine or boxer engine, features horizontally opposed cylinders arranged in two banks on either side of a central crankshaft, resembling the letter "H" when viewed from the front. This design allows for a lower center of gravity, contributing to improved vehicle stability and handling. The engine's configuration also helps balance out vibrations, resulting in a smoother operation. H-type engines are commonly found in certain models of Subaru and Porsche vehicles.
