The principle and development course of cylinder

Cylinder principle and development principle of the cylinder is the result of artillery: cylinder are derived from the cannon? This is not sensational. Your car cylinder is related to the cannon. Years, the Dutch scientists ince inspired by artillery principle, thought like power of artillery to push other machinery is not quite good? He still made burning powder explosives at the beginning, the shell into a 'piston', 'cylinder' put the gun barrel, and open a one-way valve. He injected gunpowder inside the cylinder, when lit after gunpowder, gunpowder exploded violently burning, promote the piston upward movement, and generate power. At the same time, the explosion gas pressure also opened the one-way valve, discharge waste gas. Then, residual gas in the cylinder gradually cooling, air pressure is low, the atmospheric pressure and outside the cylinder pushing the piston movement, to prepare for the next. , of course, because the journey is too long, the efficiency is too low, in the end he didn't succeed. But it is Mr Ince first proposed the 'engine', the idea of future generations on this basis that invented the automobile engine. Early use single-cylinder engine cars founder Karl Benz and Daimler in designing and manufacturing car, they all took a cylinder engine. As we don't think a car can use two or more sets of engines, as estimated at that time people would not imagine will use two or more cylinder cylinder engine. But it's different now, don't say rich countries first, and see the domestic car ads, many manufacturers total engine cylinder number and arrangement of forms, for one thing, to sell mini to blow his car is four cylinder drum machine, rather than the three cylinder with v engine must make v marked highlighted, advertising has played a very big effect really, a lot of fans have been identified with the 'cylinder is better than cylinder', 'better than cylinder cylinder' and 'v is better than straight', 'v type engine is advanced engine' and other concepts. Nearly species of chinese-made cars equipped with a v or v type engine. Single cylinder engine crankshaft turn every two weeks to produce a burning to do work, so it sounds also discontinuous flow, listen to the voice of small displacement motorcycle. Most can't let people accept that it run very smoothly, speed fluctuation is bigger, but also is not suitable for the shape of single cylinder engine in the car. To that end, the car has not see single cylinder engine, two cylinder machine is also not good looking for, at least is cylinder engine. Domestic production wally van, old xiali car, geely lofty sentiments and autoart, fryer, loading is cylinder machine. Litre of mini car multi-purpose machine, cylinder to liters engines generally USES cylinder or cylinder machine. Rise above the engine cylinder, mostly liters engines use accounted for the vast majority of cylinder. Under the condition of the same displacement, increase the number of cylinders can improve the speed of the engine, which can improve the output power of the engine. In addition, increase the number of cylinders can make the engine run more smoothly, make its output torque and power output is more stable. Increase the number of cylinders can gets easier to start, speed up more responsive. In order to improve the performance of the gas car must increase the number of cylinders. Therefore, luxury cars, sports cars, car such as high-performance gas above the number of cylinders in the cylinder, the bulls have reached cylinder. However, the increase of the number of cylinders can't unlimited. Because with the increase of number of cylinders, engine parts number also increases proportionately, so that the engine structure is complex, reduce the reliability of the engine, increase the engine weight, improve the manufacturing cost and use cost, any increase in fuel consumption, and the volume of the engine. Gas car engine, therefore, the number of cylinders are based on the purpose and performance requirements of engine, after weighing the advantages to make the right choice. Stand side by side in a row. Inline engines inline engines ( 行引擎) , it all cylinders are arranged in a plane, side by side of the cylinder block and crankshaft structure is simple, and the use of a cylinder head, low manufacturing cost, high stability, low speed torque characteristic is good, less fuel consumption, compact size, and is widely applied. Its defect is low power. Representatives of 'inline' available l, followed by the number of cylinders is engine code, modern cars are l, l, l, l engine. Straight cylinder ( l） 。
