The fuel injected 4A-FE is the successor of the carbureted 4A-F. It was manufactured between 1987–2001. Toyota designed this engine with fuel economy in mind. The 4A-FE is basically the same as the 4A-F (introduced in the previous generation of Corollas), the most apparent difference being the electronic fuel injection system as noted by the E. The engine was succeeded by the 3ZZ-FE, a 1.6-liter engine with VVT-i technology.
There are three generations of this engine and can be identified by the external shape of the engine. The first generation (1987–1993) featured a plate on the head which read "16 valve EFI" and fuel injectors in the head.[13]
The second generation had a higher profile cam design in the head, a cam cover with ribs throughout its length, and fuel injectors in the intake manifold runners. Mechanically, the late-model motors received MAP load sensing and redesigned pistons, intake ports, and intake manifold. The second generation engine was produced from 1992–1998 (1993–1997 in the US).[13]
The third generation (1997–2001) was released exclusively for the Asian market (Japan, Philippines, Thailand, Indonesia, and Malaysia) only. Although it is very similar to the second generation externally, it only has a slight difference in the top section of the intake manifold and throttle body. This last generation also has a higher additional output of 3.7 kW (5 bhp) compared to the second generation[WIKI]
