The Mitsubishi 4N1 engines are a family of all-alloy four-cylinder diesel engines developed by Mitsubishi Motors and built at its powertrain facility in Kyoto, Japan, for the company's small and mid-sized passenger cars worldwide. Mitsubishi Motors, Mitsubishi Heavy Industries and Renault announced a joint development project in June 2006 for clean diesels aimed at Europe, and the 1.8 litre version first appeared in the Concept-cX test car shown in 2007, with the 2.3 litre version following in the Concept-ZT. The family has an aluminium block, double overhead camshafts, four valves per cylinder, a high-pressure common rail injection system and a variable-geometry turbocharger, and it was the first passenger car diesel family to use variable valve timing on the intake side. It was designed to meet US Tier 2 Bin 5, Euro 5 and Japanese post new long term emission rules. The 4N13, 4N14, 4N15 and 4N16 variants have been fitted to vehicles including the Mitsubishi Outlander, ASX, Triton and Pajero Sport.
