Neljäsylinteriseen

Neljäsylinteriseen refers to a four-cylinder engine configuration. This arrangement features four cylinders in a straight line, typically mounted on a single crankshaft. It is a common and widely used engine design in automobiles, motorcycles, and various other machinery due to its balance of performance, efficiency, and cost-effectiveness.

The inline-four engine's popularity stems from its relative simplicity in design and manufacturing compared to other configurations like V-engines or boxer engines. The inline layout allows for a compact engine package, making it suitable for a wide range of vehicle sizes. Furthermore, the inherent balance of a four-cylinder inline engine, especially with a correctly weighted crankshaft and counterweights, can minimize vibrations.

Different bore and stroke combinations can be used to tailor the engine's characteristics, allowing for either a focus on high-revving power or strong low-end torque. Fuel delivery can be achieved through various methods, including carburetors or modern fuel injection systems. Ignition is typically managed by a distributor or, more commonly now, by individual coil-on-plug systems. The four-stroke cycle, consisting of intake, compression, power, and exhaust strokes, is standard for these engines.
