What is cylinder working volume? Total cylinder volume, cylinder compression ratio?

1) Combustion chamber volume: When the piston is at the top dead center, the volume between the piston top and the cylinder head is called the combustion chamber volume. Represented by VC.

2) Total cylinder volume: When the piston is at the bottom dead center, the volume of the space above the piston top is called the total cylinder volume. It is denoted by va.

3) Cylinder working volume: The volume of space swept by the piston when the piston moves from the top dead center to the bottom dead center or has the bottom dead center to move to the top dead center, which is called the cylinder working volume. Expressed by VH.

4) Compression ratio.

The ratio of the total cylinder volume to the combustion chamber volume is called the compression ratio. i.e. VA VC

Supplement: 1) Top dead center: The position where the piston moves in the cylinder and the top of its piston reaches the highest point is called top dead center. That is, the top of the piston is far from the crankshaft.

The farthest point of the carousel center.

2) Bottom dead center: The position where the piston moves in the cylinder and the top of the piston reaches the lowest point is called the bottom dead center. That is, the top of the piston is closest to the center of rotation of the crankshaft.

3) Piston stroke: The piston moves in the cylinder, and the distance between its upper and lower dead center points is called piston stroke. It is denoted by s.

4) Crank radius: the distance from the axis line of the crank connecting rod journal to the axis line of the main journal, which is called the crankshaft radius. Denoted by r. The magnitude of the piston stroke depends on the radius of the crankshaft, and the relationship is as follows: the piston stroke S is equal to 2 times the radius of the crankshaft r, i.e. s = 2r.

5) Internal combustion engine displacement: The sum of the working volumes of each cylinder of a multi-cylinder engine is called displacement. Represented by VL. That is, vl=i*vh, i is the number of cylinders.

6) Duty cycle: The internal combustion engine completes each suction, compression, and work.

and the exhaust work process, which is called a duty cycle.

7) Two-stroke internal combustion engine: An internal combustion engine that completes a working cycle with each revolution of the crankshaft.

8) Four-stroke internal combustion engine.

An internal combustion engine that completes a duty cycle every two revolutions of the crankshaft.

9) Working condition: The working state of the internal combustion engine at a certain time is called the working condition. Generally, it is expressed in terms of the speed and load of the internal combustion engine.

No, it should be the ratio of the total volume to the combustion chamber volume (compression chamber volume), that is, (working volume + combustion chamber volume) combustion chamber volume.

The volume between top and bottom dead center is called cylinder working volume. The sum of the volume of the combustion chamber and the working volume of the cylinder is the total volume of the cylinder. The ratio of the total volume of the cylinder to the volume of the combustion chamber is called the cylinder compression ratio.

Cylinder volume vh = d*d*s 4. where d is the cylinder diameter and s is the piston stroke.

Cylinder volume and displacement are different. Displacement is the volume swept by the piston during reciprocating motion, that is, the effective volume, while the cylinder volume is the total volume of the cylinder. The cylinder volume is greater than the displacement, and the car works by burning fuel, which is compressed in the cylinder first, and then instantaneously burned and expanded to provide power.

The compression ratio of the general car is about 10:1, which can be understood as follows: 10 here is the cylinder volume, 1 is the invalid volume, and the difference between 9 is the displacement. If the fuel is compressed to zero volume, then the volume is equal to the displacement.

The volume between top and bottom dead center is called cylinder working volume. The sum of the volume of the combustion chamber and the working volume of the cylinder is the total volume of the cylinder. The ratio of the total volume of the cylinder to the volume of the combustion chamber is called the cylinder compression ratio.

The working volume of each cylinder adds up to the displacement of this car.

The engine is composed of several cylinders, so the volume of several cylinders, that is, the displacement of each cylinder (working volume), is the displacement of the engine of this car. Engine displacement, referred to as displacement, is the sum of the working volume of each cylinder of the engine, the product of the displacement of a single cylinder, the number of cylinders vh and the number of cylinders.

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. Displacement is a more important structural parameter, which can comprehensively measure the size of the engine. The performance index of the engine is closely related to the volume, and generally speaking, the larger the displacement of the car, the higher the power.

The unit displacement is usually used as the basis for the price of different engine sizes.

Introduction to the working volume of the cylinder

In the piston in the cylinder operation, when running to the bottom dead center, the enclosed space above the piston, the cylinder capacity actually refers to the displacement, and the special term for hydraulic transmission refers to the volume of fluid sucked in or discharged per stroke or cycle; 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 the engine displacement. It is generally expressed in liters; The engine displacement is one of the most important structural parameters, which can better represent the size of the engine than the cylinder bore and the number of cylinders, and many indicators of the engine are closely related to the exhaust; Usually the displacement is large, and the energy released by the engine per unit time is large.

The above content refers to the encyclopedia - cylinder working volume.

Cylinder working volume Cylinder working volume (cylinder displacement): The volume swept by the movement of the brigade piston from one dead center to another (upper dead center and lower dead center) is called cylinder working volume.

Generally, it is expressed by VH: VH = (4) D 2·s 10 (-6) (L) where: D - cylinder diameter, unit mm;

S-piston stroke dismantling forest or, unit: mm; Cylinder working volume @2019

1. The cylinder compression ratio is the ratio of the total volume to the combustion chamber.

2. To illustrate the technical slip parameters of the one-bridge clearance engine, it can be roughly marked with the size of power and torque, but there are many factors that affect power and torque output, and one of the important factors is the compression ratio of the engine.

3. The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. The compression ratio is one of the important parameters of the engine. The compression ratio of modern automobile engines, gasoline engines are limited by detonation, and the compression ratio is generally 8 11.

There is no knock limit for diesel engines, and the compression ratio is generally 12 22.

Cylinder working volume: refers to the stroke of the piston in the cylinder from the bottom dead center to the top dead center.

Combustion chamber volume: refers to the volume between the top of the piston and the cylinder head when the piston moves to the top dead center.

Cylinder working volume: the sum of the working volume of a single cylinder and other cylinders.

According to the above definition, it can be seen that the size and length of the engine block are different. The volume of the cylinder is also different. So the engine is different, and these three values are different.

Yes! You're right.

1) The working volume of the cylinder vh The volume of the piston swept from the bottom dead center to the upper stop between the piston;

2) Combustion chamber volume VC After the piston reaches the top dead center position, the space between the top plane of the piston and the cylinder head (unified combustion chamber) The space of the combustion chamber (separated combustion chamber) on the cylinder head.

3) Total cylinder volume: VA VH+VC (liters).

Hello dear! We are glad to answer for you, the total volume of the engine cylinder is equal to the sum of what and whatThe answer: The total volume of the engine cylinder is equal to the sum of the working volume of the cylinder and the volume of the combustion chamber, and the compression ratio is equal to the ratio of the total volume of the cylinder to the volume of the combustion chamber.

The total cylinder volume of the engine is the volume of the entire space above the top of the piston when the piston is at the bottom dead center, which is equal to the sum of the cylinder working volume and the combustion chamber volume. How the car engine worksThe engine, also known as the engine, is a machine that can convert one form of energy into another, more useful energy, usually chemical energy into mechanical energy, and sometimes it applies to both the power generation device and the entire machine including the power plant. I hope the reply will be helpful to you, if you still have any questions, you are welcome to continue to ask questions, if you are satisfied with my service, please give a thumbs up, and I wish you a happy life, peace and joy again!

The cylinder compression ratio is the degree to which the engine gas mixture is compressed, expressed as the ratio of the total cylinder leakage volume before compression to the cylinder volume (i.e., the volume of the combustion chamber) after compression.

At present, most cars use the so-called "reciprocating engine", simply put, in the engine cylinder, there is a brigade of pistons to do the return to the town again and again, covering the straight line reciprocating motion, and has been circulating, so in this cycle and continuous work itinerary has its certain range of movement.

Cylinders are divided into single-acting cylinders, double-acting cylinders, diaphragm cylinders and impact cylinders.
