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.
4J10

| Displacement | 1.8 L (1,798 cc) |
| Bore x Stroke | 86 mm × 77.4 mm (3.39 in × 3.05 in) |
| Compression ratio | 10.7:1 |
| Fuel system | ECI multiple |
| Peak power | 102 kW (139 PS; 137 hp) at 6000 rpm(jin-net) |
| Peak torque | 172 N⋅m (127 lb⋅ft)17.9kgm at 4200 rpm (jin-net) |
Applications
- 2013 Mitsubishi RVR (Japan)
- 2017 Mitsubishi Grand Lancer (Taiwan)
- 2015 Mitsubishi Lancer
Characteristics
The new 4J10 MIVEC engine features the use of a next-generation MIVEC system that continuously regulates intake valve lift, opening duration and timing. The new MIVEC system together with improved combustion stability and a reduction in piston friction provide an improvement in fuel economy without any loss in engine performance (output and torque) over the 4B10 MIVEC engine (1.8-liter, inline-4, 16-valve DOHC).
4J11
Specifications
| Engine type | Inline 4-cylinder SOHC 16v, MIVEC |
| Displacement | 2.0 L (1,998 cc) |
| Bore x Stroke | 86 mm × 86 mm (3.39 in × 3.39 in) |
| Compression ratio | 10.5:1 |
| Fuel system | Electronically controlled MPI |
| Peak power | 110 kW (150 PS) at 6000 rpm |
| Peak torque | 195 N⋅m (144 lb⋅ft) at 4100-4200 rpm |
Applications
- 2013-2019 Mitsubishi Outlander
- 2020- Mitsubishi ASX
Characteristics
The 4J11 engine is the newly developed engine further improving the fuel economy. This engine can keep the same output performance as the conventional 4B11 engine by using the new MIVEC system.
