Mitsubishi Pajero Sport 2014.
The new Pajero Sport, launched in August last year, marks the comeback of Mitsubishi with the spirit that the Japanese joint venture has set as “To reach the new peak is the QUALITY”. This spirit is clearly shown through the journey of conquering Vietnam, with more than 2,200km along with the Pajero Sport. Pajero Sport has successfully completed 5 stages of the longest journey in the S-shaped land strip with 20 families, overcoming nearly 20 big and small passes, roaming over 100km of off-road, sand dunes, pristine beaches…
The durability and excellent performance of Pajero Sport comes from Mitsubishi’s “core values”, which are the MIVEC engine technology, the Super Select 4WD system, and the intelligent INVECS-II 5-speed automatic transmission.
How the new MIVEC engine works.
MIVEC engine technology
Mitsubishi began production of engines that apply MIVEC technology (Mitsubishi Innovative Valve Timing Electronic Control System) in 1993. At that time, MIVEC was at the forefront of technologies that help save fuel consumption of about 16km for 1 liter of gasoline when moving in the city (equivalent to 6.26 liters/100km).
This is one of the first technologies in the solutions to improve power and protect the environment by affecting the fuel injection system.
The MIVEC engine is one of the first technologies in the solutions to improve power and protect the environment by affecting the fuel injection system.
MIVEC technology uses different cam shapes to open the intake valves in two engine modes: low speed and high speed, helping to increase the maximum power and torque in the engine’s working modes. When the engine operates at low RPM, MIVEC will select a small cam shape and provide a stable combustion mixture with less exhaust gas. When the throttle is opened and the engine speed increases, MIVEC will allow to increase the timing and opening stroke of the intake valves, so it will provide the engine with greater power and torque compared to engines that do not use this technology.

Power and torque of the engine are achieved when using MIVEC in 2 modes
The special feature of the MIVEC technology is its arrangement on the camshaft with 3 different cam shapes. The largest cam shape is placed in the middle, and the two smaller and medium cam shapes are placed on either side (as shown in figure 2), although there are these 3 cam shapes, they only create 2 engine modes: Low speed mode, using small, medium cam shapes and high speed mode using a large cam shape. In low speed mode, the intake valves are driven by two small and medium cam shapes and will be independently controlled by two separate rocker arms, while this large cam shape is directly driven by the T-junction, this T-junction will control the timing and opening stroke of both intake valves when the engine is running in high speed mode.
Drive arrangement of intake valves
When the engine is running in low speed mode, the T-junction is still connected to the large cam shape, but at this time it only moves freely and does not contact with the rocker arms of the intake valves. At that time, the small and medium cam shapes driven by the camshaft will control the appropriate lift and opening time for the intake valves. Inside the rocker arm, there are pistons compressed by springs, and at that time, the T-junction will move freely and does not control the rocker arms. In addition, using two different cam shapes to open the intake valves in low speed mode helps create a swirl for the incoming air inside the cylinder, making the combustion process stable and reducing emissions.
Structure of the MIVEC system
When the engine is in high speed mode: MIVEC will control the valve opening oil to increase the oil pressure to the piston, causing the piston to lift up and contact the T-junction, at that time the large cam shape will act on both rocker arms and control the opening and closing of the intake valves. Thanks to the larger cam shape, it will increase the opening time and stroke of the intake valves, so it will increase the power and torque of the engine.
At present, this technology has been equipped on the new Pajero Sport in the Vietnamese market. The new Pajero Sport uses a V6 MIVEC 3.0L engine with a power of 220 horsepower at 6,250 rpm, maximum torque of 281 Nm at 4,000 rpm, along with the option of 1 cầu (4×2) or 2 cầu (4×4) drivetrain.
Super Select 4WD system
In addition to the MIVEC engine technology, the Super Select system is also a noteworthy feature of the Pajero Sport. Mitsubishi’s reputable 4WD system has helped the company’s racing team win 12 victories at the Dakar Rally.
Super Select system makes it easy for drivers to operate Pajero Sport.
This system combines the advantages of the 2WD active mode and the 4WD active mode on the Super Select 4WD system, allowing the transfer of modes from 2WD to 4WD even when the car is running at a speed of 100 km/h.
With the Super Select system, drivers can use the 2WD mode for flat road conditions with smoothness, low noise level, and the lowest fuel consumption. In addition, the 4H mode helps the vehicle operate stably and smoothly on the highway, improving the grip on slippery roads. With just a simple operation of pushing the transfer lever, you can switch to 4WD mode.
INVECS transmission
In addition to the impressive MIVEC engine technology, the Super Select 4WD system, Pajero Sport also attracts attention with INVECS technology. This is an intelligent automatic transmission control program applied by Mitsubishi on automatic transmissions (INVECS-II applies to step gears and INVECS-III applies to continuously variable transmissions – CVT).

Intelligent INVECS transmission.
In a simple understanding, the INVECS transmission is an automatic transmission controlled by a computer, with the ability to “learn” the driving style of the driver with the “Adaptive Control” program. As soon as the car starts moving, the computer will start “observing” the driver’s driving style, such as throttle input, coordination between the accelerator and brake… After a short period of testing the shifting programs, the computer will determine the most appropriate shifting program for the driver’s driving style. This control program can be imagined as having someone sitting next to you to monitor your driving style and then adjust the automatic transmission to match.
A reliable choice
With the “top” technologies combined with a series of improvements in appearance, cabin space, the new Mitsubishi Pajero Sport is truly a strong contender in the 7-seater SUV segment and a reliable choice for those who love family vehicles.
