Car engines are a specialty in mechanics on their own, and there is so much ground to cover if you want to master the mechanics of a car engine. From smaller (4 cylinder) engines to high-performance engines like the V20, to diesel engines and other internal combustion engine types, we go over the basics and more. You may have come across terminology like ‘four-cylinder,’ ‘V8,’ or ‘straight-six’ while reading our in-depth assessments. You may be aware that this has something to do with the engine, but what precisely does it imply, and how do various engines differ? The configuration of an engine might change for a variety of reasons, including making it easier to fit under the hood, improving smoothness, or even increasing fuel economy. The most frequent variants are inline, which is when all of the engine’s cylinders are lined up in a straight line, pointing upwards and typically perpendicular to the vehicle. The great majority of home hot hatches and smaller automobiles use this arrangement. Straight: Similar to inline, except instead of running across the engine room, the cylinders run parallel to the car from front to rear. This configuration is common in high-end vehicles, particularly BMWs. The cylinders are placed in a ‘V’ form when looking at the engine from the front. Because it allows you to fit more cylinders into a smaller area than inline engines, this type is usually reserved for luxury and high performance vehicles. Flat is sometimes referred to as a ‘boxer’ or a laterally surface. This serves to maintain the center of gravity low, which improves handling. Porsche and Subaru are the only vehicle makers that now offer flat engines in their lineups. The Volkswagen Group created the VR engine. Aside from the types there is a question on how it works, how can it be fixed, what are the types of air intakes each type needs and much more. In this line of articles everything will be answered.
