L is an abbreviation for liter, which here refers to the displacement of the engine in liters.
liters are expressed as l in the International System of Units and the secondary unit is milliliters (ml) The conversion relationship between liters and other units of capacity is:
1l = 1000ml = cubic meter = 1 cubic decimeter = 1000 cubic centimeter.
Displacement is the sum of the working volume of each cylinder of the engine, which is the volume swept by the piston from top dead center to bottom dead center multiplied by the number of cylinders. Displacement is a more important structural parameter, it can comprehensively measure the size of the engine, the performance index of the engine and the displacement are closely related, generally speaking, the larger the displacement of the car, the higher the power. The unit displacement is usually used as the basis for evaluating different engine sizes.

L (liter) is the unit of displacement, and the quantification unit of displacement is cc (milliliter).
Engine displacement (engine displacement) is the sum of the working volume of each cylinder of the engine, the product of the displacement of a single cylinder vh and the number of cylinders I. The 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. The sum of the working volume of each cylinder in a multi-cylinder engine is called the engine displacement.
Generally expressed by VL: VL=VH I=S* *D2 (4*106) where: VH cylinder working volume; i Number of cylinders.
Displacement refers to the volume of the piston in the cylinder from the top dead center to the bottom dead center, and then multiplied by the number of cylinders to obtain the displacement of the engine, referred to as displacement. From the perspective of the engine alone, the fuel consumption of the engine is directly proportional to the displacement. But in terms of vehicles, it's not so simple.
Refers to the displacement of the car is liters. l is the unit of liters.
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, just like a teenager boy is of course more efficient than a healthy adult. So those off-road vehicles and sports cars usually have a relatively large displacement.
-
Approximately equal to displacement, it mainly depends on how your turbine works and the number of starting revolutions.
The fixed displacement of the 5T engine is liters, and now the mainstream engine power values are at the level of naturally aspirated engines, and some can even reach the power level of naturally aspirated engines.
The l where it is a unit, liter, so it can be omitted. In other words, it is a naturally aspirated engine with turbocharging. The performance is equivalent, and the fuel consumption is about the same.
-
Represents a naturally aspirated engine with a displacement of liters.
Displacement is a more important structural parameter, it can comprehensively measure the size of the engine, the performance index of the engine and the displacement are closely related, generally speaking, the larger the displacement of the car, the higher the power. The unit displacement is usually used as the basis for evaluating different engine sizes.
According to the standards of Chinese mainland, it is divided into: mini car (displacement of less than 1L), ordinary car (displacement of intermediate car (displacement of medium and high-end car (displacement of high-end car (displacement of more than 4L).

It refers to the engine displacement, which is an important parameter to measure the engine.
Generally speaking, the larger the displacement, the more power you can hold and, of course, the higher the fuel consumption.
Generally speaking, for different levels of cars, there will be a range of comprehensive fuel consumption, such as: compact cars, 100 kilometers of comprehensive fuel consumption between 6-8; There are about 8-10 medium-sized cars; There are more than 10 large cars.
SUVs need to add 2-3 fuels on top of cars of the same displacement. Of course, due to the differences in engine technology of various car manufacturers, there will also be some special cases.
In addition to the impact of engine displacement and technology when the car leaves the factory, fuel consumption has many influencing factors, such as the driver's driving habits, driving conditions, etc. , so please add how to save fuel in driving habits:
First, don't slam on the accelerator when you start. When the car starts, lightly pressing the throttle is a more fuel-efficient way to get the car off to a slow start.
Second, maintain a reasonable speed and drive at a constant speed. The speed of 60-90 kilometers per hour is a relatively fuel-efficient speed. Try not to be fast and not too slow.
Fourth, avoid running long distances at low speeds. At low speeds, fuel consumption is high. As long as you can run at high speeds, it is recommended to keep the car above 60 km h.

It means that the engine displacement is, and the displacement is the main parameter that is crucial to measure an engine.
Generally speaking, the larger the displacement, the more power and of course the higher the fuel consumption.
In most cases, for cars of different socks of unknown grades, there is basically a range of comprehensive fuel consumption, such as: compact cars, comprehensive fuel consumption per 100 kilometers is between 6-8; There are about 8-10 medium-sized cars; There are more than 10 large cars.
SUVs need to be refueled 2-3 times on the basis of cars of the same displacement. Of course, there will be some special cases because of the differences in engine technology of various car manufacturers.
Fuel consumption, in addition to the relationship between engine displacement and technology when the car leaves the factory, there are many related factors, such as the driver's driving habits, driving road conditions, etc. So what to do in your driving habits to make up for the fuel saving:
First, don't step on the gas pedal when you start. When the car starts, lightly pressing the throttle is a fairly fuel-efficient way to get the car off to a slow start.
Second, maintain a reasonable speed and drive at a constant speed. The speed is 60-90km h, which is quite fuel-efficient. Try not to rush or slow.
Fourth, prevent and stop low-speed long-distance running. At low speeds, fuel consumption is high. It is argued that the car only needs to be able to drive and maintain a speed of more than 60 km h.
That's all for that. I hope Bian Xiao's introduction today can help everyone. If you like it, give Bian Xiao a compliment. This is the biggest support for Bian Xiao.
