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

Inline four cylinder also has more inline three cylinder such as QQ Alto 1 exhaust quantity is 3 cylinder car more than 1.1 more is an inline four cylinder, there are a lot of things such as the 4 cylinder 1.1 exhaust inline four cylinder exhaust should be maximum may the most thing on the market to see the 2.4 peak is over the are also basic V type arrangement of 6 cylinder engines such as Teana. Anyway market mountain car multi part or 4 cylinder 1.6 gold displacement domestic car now for more than 1.5 1.5T but also four cylinder car, row rule is the larger the gas cylinder may response number for small cars. At present, the world cylinder maximum number production model is Bugatti Veyron EB Veyron - 16.4 the car engine is popular R & D 16 cylinder 64 valve engine, with four turbochargers, using W type cylinder layout displacement: 7993 CC in 3 seconds can make the car to reach 100 km/h speed, start to accelerate from standstill to 300 km/h speed the time required for less than 14 seconds

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

First of all, the piston is not round, and the side view is not square. This is due to thermal expansion at different parts of the piston in a high temperature environment.The local minimum gap of about 0.04, depending on the design, the smallest place probably in the piston to stop opening of the lower end of 15 to 20mm perpendicular to the piston pin position, of course not absolute, the design of the skirt length is not the same.The largest part of the gap is the fire bank, which is the place above the first ring, usually at 0,7~0.8mm

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

The number of cylinder intake valve + exhaust valve is the cylinder valve number.Usually each cylinder has an inlet valve + an exhaust valve. Certain brands of engines will have more than one intake valve.

Q:Can 1 of the displacement be V6 cylinder or 6 displacement with L4 cylinder?

In fact, there is no direct relationship between what, 1.0L V6 can be made in theory, but not what is necessary, because the inline engine has its own advantages, and if you do, it is bound to each cylinder can be greatly reduced, so that the engine is of no practical use! And the cost will be high!As a large displacement engine, a straight line if the space occupied by the engine will be large, so large and bulky, the car's head by the pressure is too large, the front must be extended, from a cost perspective, The loss outweighs the gain!

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

Diesel is not easy to ignite, so it uses compression ignition, and gasoline engines use spark plugs to ignite gasoline. Can the pressure on the diesel fuel burn less? This is also an important reason for the low noise of gasoline engines.

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 mode of the cylinder is divided into the suction stroke, the compression stroke, the work stroke and the exhaust stroke.Two,(1): the intake stroke the intake valve opens, the exhaust valve closes and the downward movement of the piston, a mixture of gasoline and air into the cylinder; (2) the compression stroke, the intake valve and exhaust valve are closed, the piston moves upwards, the fuel mixture is compressed; (3) stroke: at the end of the compression stroke, the spark plug the spark, fuel burning fiercely, gas of high temperature and high pressure. High temperature and high pressure gas pushes the piston downward, which drives the crankshaft to rotate and works externally;(4) exhaust stroke: the intake valve closes, the exhaust valve opens, the piston moves upward, and the exhaust is expelled from the cylinder. (schematic diagram of the following four strokes).?Turn left and turn right |

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

Arrangement of cylindersType W arrangement and type VMany people think like V type engine cylinder arranged in a V shape, arrangement of W engine cylinder must be in a W shape, in fact, it is only approximate W shaped arrangement, strictly speaking should also belong to V type engine, at least is a variant of V engine.The V engine of each side of the cylinder and then a small angle stagger (such as Passat W8 small angle of 15 degrees), it has become a W engine. Or W engine cylinder arrangement is composed of two small V shape, a large V shape.Compared with W type and V type engine engine can be made shorter, the crankshaft can also be shorter, so the engine can save space, but also can lighten the weight, but its width is larger, so that the engine room is full.The biggest problem with W engines relative to the V engines is that the engine is divided into two parts by a whole, which inevitably causes a lot of vibration at the time of operation. To solve this problem, the Volkswagen designed two reverse rotating balance shafts on the W engine, allowing the vibration of the two parts to cancel each other in the interior.Volkswagen has three types of W engines, W8, W12 and W16

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

Carburetor is the car; its flow is; from; the tank to the oil pipe to the gasoline pump; through the gasoline to the carburetor and air atomization; fuel injection nozzle into the cylinder. The EFI engine is the sensor to signal to the engine ECU to storage, instructions to the actuator, actuator and then according to feedback data necessary adjustment, supply nozzle oil quantity into the cylinder.

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
