| − | The '''4A9x family''' was designed by Mitsubishi to replace the [[Orion]] engine in its small vehicles. Mitsubishi designed it to be lightweight, compact and powerful. All 4A9x engines feature an all-aluminium design with chain driven double overhead camshafts, four valves per cylinder (16 in total) and [[MIVEC]] on the intake camshaft. | + | {{Infobox engine |

| + | The '''4A9x family''' was designed by Mitsubishi to replace the [[Orion]] engine in its small vehicles. Mitsubishi designed it to be lightweight, compact and powerful. All 4A9x engines feature an all-aluminium design with chain driven double overhead camshafts, four valves per cylinder (16 in total) and continuously variable [[MIVEC]] on the intake camshaft. It is the first Mitsubishi engine to use a high pressure die-cast aluminium block. | ||
The engine has been built at the joint Mitsubishi Daimler-Chrysler facility - [[MDC Power]] in Germany since 2003 and the Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co Ltd in China since 2009. | The engine has been built at the joint Mitsubishi Daimler-Chrysler facility - [[MDC Power]] in Germany since 2003 and the Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co Ltd in China since 2009. | ||
