In the MIVEC system, there are three distinct cam profiles that create two engine modes: a low-speed mode, consisting of low- and mid-lift cam profiles and a high-speed mode.
The enhanced power output of the MIVEC system is achieved by its ability to vary the lift and duration of the intake valves. But when the throttle is opened wide and engine speed reaches 4300 rpm, MIVEC allows the intake valves a longer duration and longer stroke, thus providing maximum and efficient power and torque over a broader range of engine speeds. Under low-rev conditions, MIVEC selects the smaller cam profile, yielding medium lift on the cam profile which provides stable combustion and lower emissions.
The MIVEC system features separate cam profiles for high and low engine speed modes, which translates to higher maximum power and increased usable torque in the widest variety of driving conditions. The 2.4-liter SOHC four-cylinder engine utilizes advanced Mitsubishi Innovative Valve timing and lift Electronic Control (MIVEC) system technology to improve power output over a wide rpm range without sacrificing emissions or fuel economy in the process.

of torque (4000 rpm) with the aid of its patented Mitsubishi Innovative Variable timing and lift Electronic Control (MIVEC) system.īreaking new ground in performance, the Eclipse GT is powered by a high-displacement, high-output 3.8-liter SOHC MIVEC V6 engine (6G75) mated to a choice of either a six-speed manual or five-speed Sportronic(TM) transmission. The four-cylinder engine (designated 4G69) delivers 162 horsepower (6000 rpm) and 162 lbs.-ft. The Eclipse GS is equipped with a MIVEC-enhanced 2.4-liter four-cylinder engine mated to either a five-speed manual or four-speed automatic transmission with Sportronic(TM) that allows the driver to select the shift points. The 2006 Mitsubishi Eclipse is available with a choice of two powerful new engines.
