Mitsubishi Motors has developed two new MIVEC (Mitsubishi Innovative Valve timing Electronic Control) aluminum cylinder block engines including fuel consumption 660cc three-cylinder-model with increased power and a decrease of its predecessor.

Mitsubishi will use the new machine in two new vehicles scheduled for introduction in the Japanese domestic market this fiscal year end.

The new concept minicar i, scheduled to join Mitsubishi's lineup in January next year, will use 3-cylinder MIVEC engine new 660cc. The new Outlander SUV, due to debut in showrooms this October, which will be powered by engines of new 2.4-liter four-cylinder MIVEC.

In addition to the control valve timing and a block of aluminum (which gives 10% weight reduction), the new engine also uses the following to reduce the weight, size and cost, and to provide more power and fuel economy better:
  • 4-valve direct-drive valvetrain
  • Timing chain
  • Resin components (including the intake manifold, headgear)
  • Rear exhaust engine mounting layout
New 3-cylinder, 660cc turbocharged engine provides 47kW (63 hp) of power. With variable valve timing, fuel is expected to increase by 15% eceonomy the mini-car unit today, and to obtain a 3-star LEV rating for emission levels 50% cleaner than Japanese 2005 Low-Emission Vehicle requirements.

With the midship location and 45 degrees tilted back, the new engine allows a greater flexibility in developing the front end and also a longer wheelbase.

New four-cylinder 2.4-liter MIVEC engine that will be a major generator Mitsubishi Mitsubishi-use intake and exhaust ports of cylinder head design and the intake / exhaust system with dual-wall stainless exhaust manifold and high-performance catalytic converters.

New 2.4-liter engine provides 5% increase in power over the 2.4-liter MIVEC engine today along with fuel economy 5% better than Japan's 2010 standards fuel economy.

Design base 2.4-liter MIVEC engine was developed through the project Engine World alliance between Mitsubishi, Chrysler Group and Hyundai Motors.
