MIVEC..The Best Mitsubishi Engines

MIVEC

Remarkable MIVEC Engine makes power performance and environmental protection compatible

MIVEC = Mitsubishi Innovative Valve timing Electronic Control system

The dual-intake valve camshaft enables changing between low-speed and high-speed modes, resulting in easy operation from low to high rpms, improving the driving experience when starting from a stop light, merging onto the freeway, or accelerating to overtake another car. In the pursuit of pure driving enjoyment, potentially incompatible goals like fuel economy, environment-friendliness, and clean driving have all been achieved.

[Low-speed Mode]
The difference in the dual-intake valve lift (low lift and medium lift) and enhanced in-cylinder streaming further stabilize combustion without compromising fuel economy, emissions, and torque.

[High-speed Mode]
Extending the injection valve opening time and expanding the valve lift range increases intake air mass and achieves output close to best in class.
The Grandis is equipped with the 2.4L MIVEC and the Colt is equipped with with the 1.3 and 1.5L MIVEC.

On the same principle will be build the other 3 cilinders engine - 3G83 with turbo compressor. It will start assembling in this 2006 year in the "city" cars.

At the other handMitsubishi 6G75 3.8 V6 engive gets the prestige awards - Society of Engineers Australasia’s Automotive Excellence Awards.



This engine is based on the USA 3.8L V6 MITSUBISHI GALANT model. This engive covers EURO-3 and EURO-4 standarts. The Mitsubishi 6G75 engine is the pretty large V6 engine with 4 valves per cylinder making 235 horsepower at 5250rpm and 343Nm of torque at 4000rpm. There is a 5-speed INVECS-II automatic transmission option, and also a 5-speed manual transmission.

thanx bro

thanks for these information good job !!
