Toyota A engine

The Toyota A engine is a family of inline-four internal combustion engines, with displacements from 1.3 to 1.8 litres, built by Toyota Motor Corporation. The blocks are cast iron with aluminum cylinder heads, and the cylinders are siamesed so that the engine is as short as possible. Development began in the late 1970s, when Toyota wanted an entirely new engine for the Tercel, the successor to its K engine, with good fuel efficiency and performance and low emissions. The family includes the 4A-GE, one of the first Japanese mass-production DOHC four-valve-per-cylinder engines, and a later version of that engine was one of the first production five-valve-per-cylinder engines. The first member, the 1.5 litre 1A, was built from 1978 to 1980 and measured only 550 millimetres in length. Tianjin FAW Xiali, a Toyota joint venture partner, builds the 1.3 litre 8A and resumed production of the 5A in 2007. In the Transport Atlas it stands among the compact petrol-era car engines that powered the Tercel, Corolla and their relatives.
