Q:What's the average number of cylinders in a car? What's the law?

There are usually 3 cylinders, such as xiali. There are four cylinders, that is more common, and there are 6 and 8, and look at it will understand

Q:A small toy aircraft with an engine model of COX 049 and a piston about 11MM in diameter

0. 25-0.8 this is not possible. It should be within 0.01 plus or minus

Q:I want to buy a Jetta, it can valve number two, another car is four, really a bit puzzled.

The valve, as the name suggests, is the inlet and outlet of the valve. When the engine is to work, it has to burn gasoline, and when it is burning, it has air. The valve is the device that controls the intake and discharge of the cylinder. The amount of output and the performance of the engine valve number is a direct influence is undeniable, the design of multi valve intake and exhaust design and the exhaust system, for peak horsepower output absolutely has a critical impact.The valve number of the engine is generally divided into 2 valves per cylinder, or 4 valves per cylinder, and a small number of valves with 5 valves per cylinder. It is worth noting that the car parameters often in two forms of "four cylinder four valve, inline four cylinder 16 valve," said the two represents the engine is four cylinder, 4 valves per cylinder, valve number for 16The number of cylinders used in automobile engines is 3, 4, 5, 6, 8, 10 and 12 cylinders. Displacement of 1 liters below the engine, commonly used 3 cylinder (such as Xiali 7100), 1 - 2.5 liters, usually 4 cylinder engine, 3 liters or so of the engine is generally 6 cylinder, 4 liters or so for the 8 cylinder, more than 5.5 liters with 12 cylinder engine. According to the arrangement of the engine, and can be divided into W type 12 cylinder engine (such as W12, Audi A8W12, Volkswagen Phaeton), V type 12 cylinder engine (such as BMW, Mercedes Benz S600, 760), W type 8 cylinder engine (such as W8, Passat) V 8 cylinder engine (such as Audi A6L4.2), boxer 6 cylinder engine (such as Subaru V, forester) type 6 cylinder engine, inline 5 cylinder engine and inline 4 cylinder engine. Generally speaking, in the same cylinder diameter, cylinder number, larger displacement, higher power; in the same displacement, cylinder number, diameter is smaller, speed can be improved, so as to get bigger promotion power.

Q:How much is the cylinder pressure of the gasoline engine lower than that of the diesel engine?

Because diesel is a compression ignition... The gasoline engine ignites the spark through the spark plug to produce an electric spark that ignites the gas mixture!Because the diesel is not easy to ignite, so the compression ignition test! Remember to go to school, teach once, put the cotton into the needle tube, press needle, cotton burning course! This is the principle of diesel fuel... So it's stressful!

Q:The cylinder in the paper towel. It's not square. One piece of that one

With the hands in front of the cylinder cylinder will be squeezed, compressed, then cross direction pressure in the extrusion direction just once, you can easily turn round the tube out.

Q:Like kenisaige CCXR, with only 4.8 V8 engine can output 1032 horsepower, but the output power of ordinary V8 in 300-600 Ma, such as Porsche Panamera turbo with 4.8 V8 output power of the engine, why it is only 500 horsepower, and I see some people on the Internet car, the V6 engine can be changed to 1000 horsepower, and the output power of ordinary V6 engine is only 200-300, this is why?

The power of the engine mainly depends on engine displacement and displacement speed, when the engine speed is high, the output power of the engine is improved, the speed of the engine to have the corresponding technical guarantee can work reliably in the design and manufacture.In addition, the use of supercharging technology can increase the power of more than 30% of the engine.

Q:What is the working principle of the cylinder?

The working modes of the cylinder are divided into suction stroke, compression stroke, work stroke and exhaust stroke.Working principle；1, enter (suction) gas, at this time the intake valve open, exhaust valve closed, the air through the carburetor to form a combustible mixture into the cylinder, the piston in the cylinder down straight line movement, to reach the bottom stop point;2, compression, at this time intake valve, exhaust valve closed at the same time, the piston straight upward movement, reaching the top dead center;3, doing work, when the spark plug into the combustion chamber ignition, flammable mixture explosion, the temperature rose sharply, Peng up the piston downward movement;4, exhaust, the piston through the work done after the intersection of upward straight line movement, at this time the intake valve closed, exhaust valve open. The four stroke completes a work to drive the crankshaft to rotate the output shaft power.

Q:What's the difference between a L cylinder and a V cylinder? What's the good news?

A straight cylinder, also called a parallel cylinder, is usually a 4 cylinder or 6 cylinder.The utility model has the advantages of stability, low cost, simple structure, good running balance, small volume, high stability, low speed torque characteristic, low fuel consumption, compact size and wide application.Disadvantages: when the amount of exhaust and the number of cylinders increase, the length of the engine will increase greatly.4 cylinder inline engines are widely used in engines with a displacement of 2.2 liters or less."Inline" can be represented by L, followed by the cylinder number is the engine code, modern cars are mainly L3, L4, L5, and L6 engines.The most famous example of a 6 cylinder inline engine is the BMW M3. The main purpose of the BMW 6 cylinder inline engine is to facilitate counterweight and stability. The inline engine, though simple, is by no means a bad synonym.Model V engineThe cylinders are divided into two groups, and the adjacent cylinders are arranged in a certain angle so that the two sets of cylinders form two planes with an included angle, and the cylinder is V in shape from the side, so that the V type engine is called. The height and length of the V type engine are small, so it is convenient to be arranged on the automobile. In particular, modern cars pay more attention to aerodynamics, requiring the smaller the windward side of the car, the better the lower the hood.The common V engines are V6, V8, V10, V12. And V3, V5, and V16 (don't get stuck with some straight engines that represent valve numbers).

Q:How does the gasoline pump the tank to the cylinder?

Too simple, the gasoline engine intake system and air intake valve open, gas mixture into the cylinder, high voltage coil from high voltage and the cylinder line to the spark plug ignition, ignites the mixture, the instantaneous pressure generated in the cylinder to make the piston down, turn the crankshaft, and the other is the upward movement of the piston so, the engine cycle movement.

Q:Just saw the Audi A8L V12 engine, R8 is V10, the number of cylinders or car always feel good car should be more, so think of? Who can give a detailed account of his views on this subject?What is the purpose of the A8 V12 engine? Is it faster than R8?

Usually the number of cylinders, power is stronger, but the fuel consumption is relatively high, so the vehicle engine cylinder according to the specific needs of many, to the point of view of specific models, like A8L 4.2L and 3.6L V8 is also equipped with a V6 engine, according to the specific models and specific needs
