What's the difference between cylinder arrangement v and l?

Pacific Auto Network L refers to in-line engine. The cylinder of the engine is 90 degrees or close to 90 degrees with the horizontal plane, which is generally used for engines with less than 8 cylinders. V means V-type engine. There is an included angle between two rows of cylinders, which is generally 90 degrees or 120 degrees, and it is mostly used for engines with more than six cylinders.

The engine is the "heart" of the car, and its performance will affect the performance of the car. According to the arrangement of engine cylinders, it can be divided into L-type, V-type, H-type horizontally opposed engine, w 12/ 16 engines, etc. The displacement of the engine is equal to the sum of the working volumes of each cylinder. Increasing the number of cylinders can increase the engine displacement, improve the engine output power, make the engine run smoothly, and reduce vibration and noise.

L-type engine: also known as "linear engine", it means that the cylinders are arranged in a straight line, and all cylinders are arranged side by side in a plane at the same angle. "In-line" is generally represented by L, followed by the number of cylinders, that is, the engine code. Modern automobiles mainly have L3, L4, L5 and L6 engines.

Advantages: stability, low cost, simple structure, good running balance, small size, high stability, good low-speed torque characteristics, less oil consumption, small size and wide application.

Disadvantages: When the displacement and the number of cylinders increase, the length of the engine will increase greatly.

In-line 4-cylinder engines are generally widely used in engines with displacement less than 2.2 liters.

In-line 6-cylinder engine is the famous BMW, which embodies the top technology of today's mass production engine and is the pinnacle of in-line 6-cylinder.

V-type engine: all cylinders are divided into two groups, and adjacent cylinders are arranged together at a certain included angle, so that the two groups of cylinders form two planes with included angles, and the cylinders are V-shaped when viewed from the side, so it is called V-type engine.

V-type engine is small in height and length, which is convenient to be arranged on the car. In particular, modern cars pay more attention to aerodynamics, and the smaller the windward side of the car, the better, that is, the lower the hood.

Common V engines are V6, V8, V 10 and V 12. There are also 3, V5, V 16 (not to be confused with the valve numbers represented by some in-line engines). As the name implies, V represents the V-shaped arrangement of engine cylinders, generally 90 degrees, which can offset the vibration during operation and be more stable. There are 75 degrees and 72 degrees. Renault even used a wide-angle V 10 engine of more than 90 degrees.

Advantages: stable operation (suitable for V6, V8 and V 12) and space saving.

Disadvantages: the structure is complex, which is not conducive to maintenance and high cost. At the same time, V3 and V5, including V 10, are not very stable in structure and displacement, especially the V 103L engine, that is, the F 1 engine, which requires a lot of energy and money to ensure its stability.

Representative models: Audi A6, Ferrari 360, Porsche carrearGT and Mercedes S600. Use V6, V8, V 10 and V 12 engines respectively. V3 mainly appears on some motorcycles, and V5 is said to be used in the previous generation of Volkswagen Golf. V 16 can be found in some luxury classic cars.

H-type engine: also known as horizontally opposed engine, it is also a type of V-type engine, except that the included angle of V becomes 180 degrees, usually 4 or 6 cylinders.
