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:The cylinder in the paper towel. It's not square. One piece of that one: The easiest way is to pull the paper out.

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: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: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: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: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: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:Can 1 of the displacement be V6 cylinder or 6 displacement with L4 cylinder?: Displacement: the amount of space that is passed through the piston from the TDC to the lower dead point is called the cylinder displacement. If the engine has several cylinders, the sum of all the working volumes of the cylinder is called the engine displacement.

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
