4A91 1.5L Bare Engine / Long Block – Foton Midi, Gratour & Saga Replacement Engine
This 4A91 bare engine is a complete long block assembly built to OEM specifications for Foton vehicles. It is the 1.5-litre naturally aspirated gasoline engine from the Mitsubishi 4A9 engine family, produced by Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., Ltd. (沈阳航天三菱汽车发动机制造有限公司), commonly known as “Shenyang Mitsubishi” (航天三菱). The engine features a dual overhead camshaft (DOHC) 16-valve design with MIVEC (Mitsubishi Innovative Valve timing Electronic Control) variable valve timing, an aluminium alloy cylinder block, and a maintenance-free timing chain drive system. The block, head, crank, pistons, cam and valves are all in place, and the assembly is ready to accept your existing intake, exhaust and accessories. This engine powered a range of Foton passenger and commercial vehicles from 2010 through 2018, including the Midi, Gratour, Saga, and Monza. It remains one of the most common engines in the aftermarket for these vehicles across Asia, Africa, Latin America and the Middle East.
