Mitsubishi 4N15 2.4L DOHC 16V DI-D MIVEC Diesel Engine For Sale.

The Mitsubishi 4N15 2.4L DOHC 16-valve DI-D MIVEC diesel engine is a modern, efficient power unit designed to deliver improved performance, reduced emissions, and better fuel economy compared to earlier Mitsubishi diesel engines. Built with a 2.4-litre inline four-cylinder configuration, Double Overhead Camshafts (DOHC), 16 valves, Common Rail Direct Injection (DI-D), MIVEC variable valve timing, and a variable geometry turbocharger, this engine provides smooth power delivery and strong low-end torque.
