What does the L in 2 0L indicate, lengthened, displacement, straight series engine.

It represents the displacement and the total working volume of the lifting piston.

Generally refers to displacement, for example, liters.

Among them, L is mainly literal, which is to describe the displacement of the car.

The L of the engine refers to the engine displacement, that is, the displacement of the engine is the liter displacement. Engine displacement is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, it is more representative of the size of the engine than the bore and number of cylinders, and many indicators of the engine are closely related to the displacement volume.

Usually the displacement is large, and the energy released by the engine per unit time (that is, the chemical energy of the fuel is converted into mechanical energy) is large, that is, the "power" is good, so those off-road vehicles and sports cars usually have a relatively large displacement.

L is the meaning of displacement liter or lengthened. l is the unit of volume liter here. Refers to the exhaust volume of a car's engine. This means that this engine has a liter of displacement.

In addition, supercharging generally uses S; Turbo generally uses the term T to refer to an engine with an intake turbocharger. The turbocharging device can change the air intake of the engine, so that the fuel vapor is more fully burned in the cylinder, thereby increasing the output power of the engine. Compared with engines of the same displacement, it has the advantages of high power output, low fuel consumption, and high environmental protection.

The amount of outgassing of the reaction. Refers to the sum of all cylinder working volumes of the engine. Cylinder working volume refers to the volume of gas swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the cylinder bore and piston stroke.

This refers to the car's engine displacement is liters; Refers to the displacement of the engine of this car is liters.

l = liter, which is the volume of the engine cylinder.

L is the engine cylinder arrangement, and L stands for in-line.

The following is the content of the engine L represents: 1. The L-type engine, also known as the "lineengine" engine, refers to the cylinders arranged in a straight line, and all its cylinders are arranged shoulder to shoulder at the same angle into a plane of reeds and cherry blossoms. 2. "Inline" is generally represented by L, and the number of cylinders added behind the accomplice is the engine code, and now there are mainly L3, L4, L5, and L6 engines on the car.

Extended information: Inline 4-cylinder engines are generally widely used in engines with a liter displacement or less. The current leader of the inline 6-cylinder engine is the famous BMW, which embodies the top technology of today's mass-produced engines and can be called the pinnacle of inline 6-cylinder.

The larger the engine cylinder volume, the more power it has.

A car engine is the displacement of the engine cylinder, and L is the unit of volume, which is the English abbreviation of liter.

The volume of space through which the piston of an automobile engine moves from top dead center to bottom dead center is called cylinder displacement, and if the engine has several cylinders, the sum of the working volumes of all cylinders is called engine displacement. It is generally expressed in liters (l). It means that the displacement is the best displacement in today's automobile market.

First, because the vast majority of manufacturers spend more energy on the shape design of displacement models, the appearance appears more decent and refined, and the price of each model of this displacement can be accepted by most consumers, which is in line with the psychology of Chinese people buying a car with a good face; Second, the models generally use more advanced car-making technology.

Displacement: The volume of space through which the piston moves from top dead center to bottom dead center is called cylinder displacement, if the engine has several cylinders, the sum of the working volumes of all cylinders is called engine displacement.

The division of car classes in China is determined according to the size of the displacement. The displacement of the minicar is less than or equal to 1 0L; The displacement of ordinary cars is in the range of 1 0-1 6L; The displacement of the intermediate sedan is in the range of 1 6-2 5L; The displacement of mid-to-high-end sedans is within the range; The displacement of the premium sedan is more than 4 0 liters.

Generally, people who pursue high performance of automobiles mostly choose large-displacement engines, and people who attach importance to economy mostly choose small-displacement engines. So, is this selection criterion appropriate?

It is true that engines with large displacements are fuel-efficient, but this is only a characteristic of the engine.

In the car, the adaptability of the engine and the whole vehicle has a great impact on the economy of the car. If the adaptability of the engine with a small displacement is not good, it is likely that it will not be more fuel-efficient than the engine with a large displacement, and even more fuel-efficient than the engine with a large displacement. Especially for cars with heavy weight, if the displacement of the engine is too small, the use of small horses and large carts will inevitably make the engine run more at high speed and high load, thus consuming more gasoline.

In the case of a large-displacement engine, the amount of gasoline consumed does not change much because of the high torque and the need to press the accelerator pedal very deeply. In contrast, the result is likely to be that engines with smaller displacements are more fuel-intensive.

The L4 is an in-line four-cylinder engine.

It is an engine that literally disempowers the engine.

They are divided into 4 cylinders, each with an approximate capacity, and then arranged vertically, which is L4, and L is the meaning of Line.

So the L4 is an in-line four-cylinder engine with a literal displacement.

For example, the Camry has a displacement model, and his engine is also a straight line with 4 cylinders, so simply put, it is L4

In the case of a V6, it is a V-shaped 6-cylinder engine.

For example, Ruizhi has a displacement V-shaped arrangement, a 6-cylinder engine, written with a symbol is V6L4, V6 is just the number of engine cylinders and arrangement, generally speaking, the larger the displacement, the more engine cylinders, but the width and length of the car are limited, can not always be arranged in a straight line, so the V-shaped arrangement of the engine appeared, but BMW seems to have overcome this problem, production and application of L6 engine.

The 160 hp l4 refers to the engine being an in-line 4-cylinder arrangement.

The engine with a displacement of 160 hp or 118 kW L4 is a four-cylinder engine.

An engine is a machine that can convert other forms of energy into mechanical energy, such as internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, the internal combustion engine usually converts chemical energy into mechanical energy. An engine applies to both a power generation unit and an entire machine including a power unit (e.g

gasoline engines, aero engines).

"In-line" is also called parallel cylinder, can be represented by L, followed by the number of cylinders is the engine code, modern cars mainly have L3, L4, L5, L6 engines. Specifically, all cylinders in this layout are arranged side by side at the same angle in a plane, and only one cylinder head is used, and the structure of the cylinder block and crankshaft is relatively simple, as if the cylinders were standing in a column.

The advantages of L-type engine: stability, low cost, simple structure, good operation balance, small size, high stability, good low-speed torque characteristics, low fuel consumption, compact size, and wide application.

Most of the modern cars are front-engine front-wheel drive, which requires the engine to be placed horizontally on the front of the vehicle, and the volume of the engine is not too large, and the volume size of L4 is just right, so the in-line 4-cylinder engine has been widely used.

20L is 20 liters, L is liter, and cars turning left at T-junctions should enter the side lane before the intersection. Thank you!
