Mitsubishi 4D56 2.5L DOHC 16V DI-D Turbo Diesel Engine For Sale

The Mitsubishi 4D56 2.5L DOHC 16V DI-D turbo diesel engine represents a more modern evolution of the well-known 4D56 engine family, designed to deliver improved performance, better fuel efficiency, and lower emissions. Featuring a 2.5-litre inline four-cylinder layout, Double Overhead Camshafts (DOHC), 16 valves, Common Rail Direct Injection (DI-D), and a turbocharger, this engine provides smoother power delivery and more refined diesel operation compared to earlier mechanical versions. As a result, it became a popular choice in later-generation Mitsubishi commercial and SUV models.

The Mitsubishi 4D56 DI-D engine produces approximately 100–133 kW (136–178 hp) and up to 314 Nm of torque, depending on application and tuning. In addition, the common rail system improves throttle response and fuel economy while reducing emissions output. This makes it a strong replacement option for owners looking for a balance between performance and efficiency in a proven diesel platform.

Common Weaknesses & Maintenance Notes

Like most common rail diesel engines, the Mitsubishi 4D56 DI-D can develop injector wear, EGR carbon build-up, DPF blockage, and turbocharger strain over time. In some cases, high-pressure fuel system components may also require attention at higher mileage. Therefore, regular oil and filter changes, fuel system servicing, and consistent highway driving are essential to maintain performance and prevent carbon-related issues.
