从目前源源不断的新车型来看,越来越多的新兴技术被应用在当今的发动机上,燃油直喷技术和发动机增压技术是目前比较常见的发动机新技术。传统的发动机是将燃油喷入进气道,和空气充分混合后以可燃混合气的方式进入燃烧室内燃烧,然后在活塞压缩行程的末端通过火花塞点燃剧烈燃烧,在这个基础上发展起来了一系列进气管油电混合技术,虽然电子控制喷油量改善了早期化油器不适应各种工况的不足,但它也有一定的劣势,首先就是受进气流的影响使得燃油和空气不能得到较好的混合,而且混合气体只能在气门开启的时候进入气缸,因此 From a steady stream of new models, more and more emerging technologies are used in today’s engines, fuel injection technology and engine supercharger technology is now more common new engine technology. The traditional engine is to inject fuel into the inlet, and the air is fully mixed with the combustible mixture into the combustion chamber combustion, and then at the end of the piston compression stroke through the ignition spark ignition, developed on this basis a series of Intake pipe hybrid technology, although the electronically controlled fuel injection to improve the early carburetor does not adapt to a variety of conditions, but it also has some disadvantages, first of all is affected by the intake air so that the fuel and air can not get better Of the mixture, and the mixed gas can only enter the cylinder when the valve is open, therefore
