MIVEC ENGINE TECHNOLOGY, Main Weapon In MITSUBISHI Cars

MIVEC ENGINE TECHNOLOGY

Mitsubishi Motors has an undeniable reputation when it comes to vehicle performance in MIVEC ENGINE TECHNOLOGY. This has been proven by a series of achievements in car racing, especially rallying. But did you know that the true performance of this Mitsubishi vehicle is thanks to the engine performance which is its main weapon

Mitsubishi Motors Corporation (MMC) continues to develop various technologies in Mitsubishi vehicles. One of which is MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) technology. This MIVEC technology is the general name for all Mitsubishi engines. Which are equipped with a valve-timing mechanism (the time the air valve opens in the engine). That can be adjusted to the engine’s needs automatically.

MMC has long focused on technology to regulate valve timing and valve lift with the aim of producing high power, efficient fuel consumption and low exhaust emissions.

MIVEC Engine History

“The MIVEC engine embedded in Mitsubishi Motors vehicles has technology that not only optimizes engine power performance. But also takes into account the level of fuel consumption and efficient exhaust gases while also paying attention to environmental sustainability,”.

Guntur Harling, Group Head of Product Strategy Division PT MMKSI

The MIVEC engine was first used in 1992 on the Mitsubishi Mirage. And since then Mitsubishi Motors has added a number of enhancements to improve performance. Mitsubishi Motors then continued to develop the MIVEC engine into the All New MIVEC engine. Which controls intake valve timing and valve lift at the same time, all the time.

In 2011, Mitsubishi Motors installed the All New MIVEC SOHC (Single Over Head Camshaft). Engine on the Mitsubishi Galant Fortis model for the Japanese market and Mitsubishi Sportback Galant Fortis. In the All New MIVEC SOHC 16 Valve (4J1 model), engine performance has been further developed by adjusting the volume of incoming air. Through the valve timing and valve lift adjustment mechanisms as well as the throttle valve opening.

The 4J1 engine of this model has also reduced fuel consumption by increasing combustion stability through optimization of the combustion chamber structure. And reduction of friction through optimization of the piston structure. In addition, although the All New MIVEC engine adopts a simple SOHC structure. The performance of the engine is the same as the previous MIVEC engine.

Additionally the AS&G (Automatic Stop and Go) start-stop system achieves a smooth stop-and-start with minimal vibration along. With reduced fuel consumption at restart due to the reduction in air intake volume by the All New MIVEC system.

Mitsubishi Motors also developed the MIVEC DOHC 16-valve Engine (4B1) engine series used in the Mitsubishi Outlander and Delica D:5. As well as the Galant Fortis model using the MIVEC system which continuously. And optimally controls valve timing & valve lift on the intake and exhaust valves in accordance with engine rotation.

This system results in high engine performance and fuel efficiency. The system also continuously controls the intake cam and exhaust cam independently. This system provides a combination of maximum power output. Optimal fuel efficiency, and is very environmentally friendly by making valve control more precisely according to RPM and engine load on the intake system. just.

Mitsubishi Motors then developed the 4B11 MIVEC Twin-Scroll Turbo Engine. This engine has a further advantage with significantly improved responsiveness compared to the conventional 4G63 model. The maximum output is 221kW (300 PS) / 6,500rpm and the maximum torque is 422 Nm (43.0kgf m) / 3,500rpm (for the Japanese market).

Mitsubishi Motors designed it to deliver high torque from a lower speed range. This type of engine can achieve outstanding power performance, including improved gear ratios in the drive train. The biggest feature of this engine is the use of a die-cast aluminum cylinder block which allows a reduction in the weight of the engine itself by 12.5 kg compared to conventional iron cylinder blocks.

In this type Mitsubishi Motors also changes the layout of the intake and exhaust sides. Where the intake side is in front of the vehicle body and the exhaust side is behind. Due to this change, it is no longer necessary to place the exhaust pipe under the engine. So the engine position can be lowered by 10mm compared to conventional models.

MIVEC Engine for Mitsubishi Motors Product Range in Indonesia

MIVEC technology is also embedded in Mitsubishi Motors passenger vehicles currently marketed in Indonesia. Like Mitsubishi Motors’ flagship Small MPV model, the Mitsubishi Xpander is equipped with a 4A91 MIVEC 1.5L DOHC 16 Valve engine that has a power of up to 105PS/6,000rpm with a maximum torque of 141Nm/4,000rpm.

The capabilities and power produced by the Xpander engine make it more complete combined with various features on the car. So as to provide the best driving experience for families.

Equipped with an engine similar to the Xpander, the Xpander Cross has the same maximum power and torque. But the Xpander Cross has a combination of advanced engine. And suspension with shock-absorbing valves so that it can provide driving comfort in various terrains.

Unlike the Xpander, the Outlander Sport has a 4B11 16 Valve MIVEC DOHC engine with a capacity of 2,000 cc. Which is capable of producing maximum power of up to 150PS/ 6,000rpm. As well as maximum torque of 20.1 (197 Nm) / 4,200rpm.

Despite being in the medium SUV segment, unlike the Outlander Sport, the Eclipse Cross has a 4B40 DOHC MIVEC 1.5L engine equipped with Turbocharged. Making torque more powerful at low-medium RPM.

With a 4 (four) cylinder engine, the ECLIPSE CROSS is able to reach a maximum power of up to 150PS / 5,500rpm and with a maximum engine torque of 250 Nm / 2,000-3,500 rpm. MIVEC ENGINE TECHNOLOGY.
