V4moottori

V4moottori refers to a four-cylinder V engine configuration. In this arrangement, the cylinders are divided into two banks of two cylinders each, set at an angle to each other, forming a "V" shape. The angle between the banks can vary, commonly ranging from 20 to 90 degrees. This design offers a more compact engine package compared to an inline-four engine of similar displacement, making it advantageous for applications where space is limited, such as in smaller cars and motorcycles.

The V4 engine typically utilizes a single crankshaft to which all four pistons are connected. The firing order is designed to provide a smoother operation than some other configurations. While less common than inline-four or V6 engines, the V4 has been employed by various manufacturers throughout automotive and motorcycle history. Notable examples include certain Ford models, Lancia automobiles, and several motorcycle brands. The balance of a V4 engine can be influenced by the V-angle and the use of balance shafts. Its relatively short length contributes to a shorter wheelbase in vehicles, which can affect handling characteristics.
