How many car cylinder what cylinder pressure generally represent what car

How much automobile cylinder represents what car cylinder pressure cylinder pressure is generally how many cars? Maybe for some, this is a very vague concept. Recently, a friend asked editor this problem. Well, today I will see together with you, hope it can help for you. How many what the automobile engine cylinder is commonly used for automobile cylinder with 3, 4, 5, 6, 8, 10, 12 cylinder. 1 liter engines with commonly used three cylinder, 1 ~ 2. 5 litres for four-cylinder engine, commonly 6 cylinder engine is usually about 3 liters, 4 litres to 8 cylinders, 5. More than 5 litres with 12 cylinder engine. Number of cylinders is often the case, under the same diameter, the number of cylinders, the more the greater the displacement, the higher the power; Under the same displacement, the more number of cylinders, the smaller the diameter, rotational speed can be improved, thereby gaining greater power to ascend. In order to try to stagger the adjacent cylinder, so that the crankshaft stress even, multi-cylinder engine, there is a sequence of each referred to as the engine firing order. Ignition order depends on the structure, the design of the crankshaft and the crankshaft engine load and other factors. For example: five cylinder in-line send hijacking ignition order is: 1-2-4-5-3. Automobile cylinder pressure in general how much one, first of all, according to the rated pressure and the calculation of the standard cylinder bore to do about. Such as: air pressure 0. 5Mpa ( 5. 0985811 KGF/cm2 ( kgf/cm? ) ) , the diameter of 50 mm ( 5cm) Cross-sectional area, the cylinder = PI * ( 5/2) ^ 2 = 19. 63 ( Square centimeters) So, 0. 5 mpa under the theory of output = 5. 0985811 * 19. 63 = 100. 085 ( KGF) But only for the theory, according to the actual working condition, the efficiency will be lower. Second, rodless cavity area * working gas pressure = the piston thrust, rod cavity area * working gas pressure = return force, piston pneumatic components common design of normal operating pressure of 0. 4 million mpa, the most common air compressor output pressure of 0. 4 - 0. 7 million mpa, to promote a 700 kg of artifacts needed reasoning needs to be tested. The operation condition of the engine cylinder pressure test engine first look at the engine cylinder pressure. Most of the efi engine cylinder pressure in 1200 ~ 1400 kPa, a few high compression ratio of engine cylinder pressure is more than 1700 kPa. Original design engine cylinder pressure mainly depends on the size of the volume of the combustion chamber and the engine compression ratio, and is there a pressurization mechanism; Actual use of the main factors influencing the engine cylinder pressure have how much carbon deposition in the combustion chamber, and the sealing condition of the combustion chamber and exhaust is obstructed, etc. ( 1) Preheat and stop the engine. ( 2) Remove the engine cover. ( 3) The positive and the ignition coil primary disconnect the ignition system, make it doesn't work, and other electrical wiring insulation with electrical tape, make its can't contact with the ground wire. The ignition system without distributor, remove the four ignition coil. ( 4) Remove the four spark plugs and air gun to blow away all the dust within the pits. What more about 'how many representative automobile cylinder automobile cylinder pressure general how many' the content of the small make up is introduced here, hope useful for everyone. More auto parts information, please attention. , your car's warm harbor!
