The 2.2-liter Mitsubishi 4N14 diesel engine has been produced by the concern only since 2010 and is installed on the popular Outlander and ASX crossovers, as well as the Delica D:5 minibus. This aluminum unit highlights the presence of a proprietary phase control system such as MIVEC.
4N1 family: 4N13, 4N14, 4N15, 4N16.

Disadvantages of the Mitsubishi 4N14 engine
- At the moment, this diesel engine has shown itself only on the good side, except perhaps for a strong rattling;
- During the burning of the particulate filter, a certain amount of diesel fuel enters the oil;
- Piezo injectors do not like bad fuel and can fail even before 100,000 km;
- The EGR valve clogs up pretty quickly, and the intake flaps still get stuck from soot;
- Once every 45,000 km, the thermal clearances of the valves require adjustment with the removal of the injectors.

Correct! These verdicts are not really accurate.
Especially for the 4D56 engine!!
This page describes the 4N14 engine; the 4D56 is described at https://mymotorlist.com/engines/mitsubishi/4d56/.
They don’t have piezoelectric injection and only the 1.8l and 2.4l get MiVEC. I’m a Mitsubishi Master Technician. They are only solenoid type. Only the new 4N16 gets piezo type to adhere for AdBlue.
