Mitsubishi 4J1 engine

4J1
Overview
Manufacturer	Mitsubishi Motors
Production	2011–present
Combustion chamber
Cylinder block alloy	Aluminium die cast
Cylinder head alloy	Aluminium die cast
Valvetrain	Direct acting SOHC, 16 valves, continuously variable MIVEC intake valve timing
Chronology
Predecessor	Mitsubishi 4B1 engine

The Mitsubishi 4J1 engine is a new range of all-alloy straight-4 engines. The main goal was declared as reduction on-road CO2 emission on new vehicles.

4J10

Specifications

Engine type	Inline 4-cylinder SOHC 16v, MIVEC
Displacement	1.8 L (1,798 cc)
Bore	86 mm
Stroke	77.4 mm
Compression ratio	10.7:1
Fuel system	ECI multiple
Peak power	102 kW (139 PS) at 6000 rpm
Peak torque	172 N⋅m (17.5 kg⋅m) at 4200 rpm

Applications

• 2013 Mitsubishi RVR (Japan)

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	86 mm
Stroke	86 mm
Compression ratio	10.5:1
Fuel system	Electronically controlled MPI
Peak power	110 kW (150 PS) at 6000 rpm
Peak torque	192 N⋅m (19.6 kg⋅m) at 4200 rpm

Applications

• 2013 Mitsubishi Outlander ClearTec (Europe)

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.
