a number of cylinders
the number of cylinders: Number of cylinders commonly have 3,4,5,6,8,10,12 automotive engine cylinder. Displacement of 1 liter three-cylinder engine used, usually 1 to 2.5 l four-cylinder engine, the engine is generally about 3 liter 6 cylinder, 8-cylinder about four liters, 5.5 liters 12-cylinder engine.
In general, in the same bore, the more the number of cylinders, the greater the displacement, the higher power; in the same displacement, the more the number of cylinders, the smaller the bore, the rotational speed can be increased, to thereby obtain a larger increase power. Design and manufacture a small number of cylinders of the engine is certainly relatively easy, since each additional one cylinder, a corresponding number of valves will increase, lengthening the crankshaft, increasing the load on the crankshaft balance, increase the ignition and injection hardware hellip; hellip; these things increases have increased the complexity of the engine, the direct result is difficult to design improved manufacturing costs, and even the engine control software have become correspondingly more complex. But in the engine use and performance it is generally the earliest stages of design parameters finalized, in the case of stroke and bore have a certain limit to be increased displacement to get high-powered only by increasing the number of cylinders to achieve. So now universal design is a single-cylinder 0.5L displacement, 4,6,8,10,12-cylinder engine has a corresponding common displacement. Multi-line four cylinder engine is generally employed (L4), in-line six cylinder (L6 of) and a V-type six-cylinder (V6), V-type eight cylinder (V8) design of the structure. Three-cylinder engine and five-cylinder balancing due to poor and difficult to solve, and therefore less used, but there are Charade three-cylinder engine configuration, in our country has been discontinued Audi 100 cars use the five-cylinder engine.
