The Mitsubishi 4J1 engine is a range of all-alloy straight-4 engines. The main goal was declared as reduction on-road CO2 emission on new vehicles.[1] According to cars specifications fuel consumption also was improved. Comparing to previous engine series (4B1) valvetrain configuration was changed from DOHC to SOHC, Variable valve lift (VVL) technology added. The engine usually is paired with the ecological features like Start-Stop system and EGR. That engine mostly is appearing in the cars Lancer X, ASX, Outlander on several markets across Japan, Europe and Latin America.
