The A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads.
The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes the first mass-production DOHC, four-valve-per-cylinder engine, the 4A-GE, and a later version of the same motor was one of the first production five-valve-per-cylinder engines.
Toyota joint venture partner Tianjin FAW Xiali still produces the 1.3 L 8A and recently resumed production of the 5A.
The 1.5 L 1A was produced between 1978 and 1980. All variants were belt-driven 8-valve counter-flow SOHC engine with a single, twin-barrel downdraft carburetor.
Applications:
Using Toyota TTC-C catalytic converter.
Output:
Applications:
The 1.3 L 2A was produced from 1979 through 1989. 2A motors in 1982 onwards AL20 Tercels have a slightly different valve cover and timing belt cover than early AL11 Tercels, as well as an automatic choke, and automatically controlled hot air intake (HAI) system. It also has higher compression ratio, and reformulated combustion chambers to improve the fuel economy and emissions. All variants used belt-driven SOHC eight-valve counter-flow cylinder heads with a single downdraft carburetor.
