随着汽油机性能的不断改进和提高,从转速、功率、燃料的经济性及排气净化程度等方面,对汽化器都提出了越来越严格而完善的要求。所以,对现代汽化器来说,它必须具备在任何负荷,任何转速,任何大气压力状况下,都能适时地向发动机供给数量和浓度符合要求的可燃混合气,并使发动机的排放达到最佳标准,这就使现代汽化器的构造日趋复杂完善。下面就丰田12R型发动机汽化器的几个排气净化装置介绍如下:
With the continuous improvement and improvement of gasoline engine performance, more and more strict and perfect requirements are put forward on carburetors from the aspects of speed, power, fuel economy and exhaust gas purification. Therefore, for modern carburetors, it must be able to supply the engine with the required quantity and concentration of flammable gas in a timely manner at any load, at any speed, at any atmospheric pressure, and to achieve optimal engine emissions , Which makes the construction of modern carburetor increasingly complex and perfect. The following Toyota 12R-based engine carburetor several exhaust purification devices are as follows:
