| + | The '''Orion''' (or '''4G1x''') family of engines are inline 4 cylinder engines which were designed by Mitsubishi to replace their [[Neptune]] (4G4x) series. All have cast iron cylinder blocks, alloy heads and overhead camshafts driven by a belt. Displacement ranges from 1.2 to 1.6 Litres. | ||
| − | + | The Orion series was first introduced in the Mitsubishi Colt in 1977 and production continues today earning it the distinction of being one of the longest lived Japanese engines ever produced. The engine has seen duty in a range of other makes including Hyundai (who call it the Alpha), Proton, Smart, Haval and Geely. | |

The 4G15 is the most common of all the Orion engines. It is a 1.5 Litre engine with a displacement of 1468cc. Its bore and stroke is 75.5x82.0mm and is avaiable in SOHC 2 valve per cylinder, SOHC 3 valve per cylinder, DOHC 3 valve per cylinder and DOHC 4 valve per cylinder forms. SOHC versions use a 9.2:1 compression ratio, while the DOHC versions use a 9.5:1 compression ratio. | The 4G15 is the most common of all the Orion engines.
