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

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.

That is the intake and exhaust of the engine. It is estimated that you bought 1.6 or 2, and 1.8T has 5 cylinders per cylinder, and 20 for each. This thing is not advanced, that is, the beginning of the two valve, a little meat, and nothing else!

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

You can say all you can. Technically you can do it. It's like a motorcycle 600 with a single cylinder and 250 with a 4 cylinder.However, to consider whether it is worth, the number of engine cylinders and arranged in order to maximize the form of power and maximum stability, of course, combined with cost considerations.1 of the design into V6, then the cost will increase a lot, but the advantages can not play out, it will lose meaning.6 designed to L4, the stability is much worse, affecting the comfort of the vehicle

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

On the plane where the hard pressed on the other side and then turn 90 degrees again once and then take it 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?

Generally speaking, when the engine single cylinder exhaust quantity is invariable, the cylinder number is more, the engine total displacement is bigger, the output horsepower is bigger.In the case of constant engine cylinder number and displacement, there are three ways to increase engine power:First, increase the speed of the engine. For example, the current F1 engine, V8, has a displacement of just 2.4 (the same as the 4 cylinder Camry). Speed up to 20000 rpm, more than 800 horsepower.Two, pressurization. Supercharging is divided into mechanical supercharging and turbocharging. For example, Fawkes's 1.8 engine had 120 horsepower, while the 1.8 - meter mass 1.8T turbocharged engine was tuned to 220 (old TT).Three, using a two nitrogen oxide (commonly known as laughing gas) instead of air into the combustion chamber. They are generally used as converted vehicles for straight speed races.

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?

An automobile engine produces power by igniting a mixture of air and fuel. The working procedures of the fuel supply system are as follows:1. The fuel is pumped out of the tank by a gasoline pumpGasoline pump internal construction drawingPhysical diagram of gasoline pump2. Pass the fuel filter to the injectorGasoline filterFuel injector3. The oil mist ejected from the nozzle is mixed with air. The intake pipe is sucked into the air cylinder and is discharged by the exhaust pipe after burning.As the pressure of the pump is greater, a fuel pressure regulator is needed to return excess fuel from the return pipe to the tank.Working principle diagram of cylinderInternal structure of fuel pressure regulatorFuel pressure regulator physical mapWorking order diagram of automobile fuel supply system

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?

To a certain extent, the heat will be a problemA8 doesn't seem like V12, but W12 doesNo faster than R8, R8 is a sports car after all
