Buick Model H45
United States 1919
Buick is the oldest car brand in the history of the United States. Buick McLaughlin, produced in 1919, is also known as the H45 station wagon. Like many early Buick models, the body frame consists of car body and chassis. Since H45 uses a large number of wooden structures, as well as wheels and other distinguished atmospheric designs, this car became the most popular model in the United States in the 1920s.
Unlike the side-valve engines commonly used in other models in the same period, the 4.2L inline 6-cylinder push rod engine, equipped with the H45, integrates all other valve mechanisms except the camshaft and rocker push rod into the cylinder head, which greatly improves the wading capability. Meanwhile, the engine rocker arm, valve, and valve spring are hidden behind the cylinder head, which made the H45 have the prototype of modern engine design.
