寻求高精度目前世界上大多数使用快燃发动机的汽车还是经过汽化器供给燃料-空气混合物。自1950年第一位先驱者证明了汽油喷射的可用性之后,到六十年代才在大批量生产汽车过程中逐渐采用。纯机械系统首先同部分电子系统竞争,这一竞争一直延续到近几年来电子系统开始获得成功。这里的关键是较容易与催化剂和点火调节相结合。现在所有冲程容积较大的新型发动机都装有电子喷射系统。这里毋需再对喷射是否真比汽化器“好”的问题加以研究。以前的系统不可能,至今才有可能使喷射逐渐发挥其优点,特别是在有4个 Finding High Accuracy Most cars in the world today that use fast-burning engines are still supplied with a fuel-air mixture via a carburetor. Since the first pioneer in 1950 demonstrated the availability of gasoline jets, it was not until the 1960s that they were gradually adopted in the mass production of automobiles. The purely mechanical system first competed with some of the electronic systems and the competition continued until electronic systems became successful in recent years. The key here is easier to combine with catalyst and ignition regulation. All new stroke engines now have electronic injection systems. There is no need to study whether the injection is really more than a carburetor. The previous system was not possible and it has hitherto been possible to give the jet progressively its merits, especially when there are 4
