Mitsubishi Motors develops two new MIVEC engines
- 4-cylinder MIVEC to power new SUV Outlander in October
- 3-cylinder MIVEC to power new-concept minicar i in January 2006
Mitsubishi Motors Corporation (MMC) has developed two MIVEC (Mitsubishi Innovative Valve timing Electronic Control) aluminum cylinder block engines to power two new models slated for introduction in the domestic Japanese market later this fiscal year. The new Outlander SUV, due to debut in showrooms this October, is to be powered by a new 4-cylinder 2.4 liter MIVEC engine. The new-concept minicar i, scheduled to join the MMC lineup in January next year, will use a new 3-cylinder 660cc MIVEC engine.
Main features of new MIVEC engines
The two new MIVEC engines announced today incorporate the technologies listed below and have been developed with a common concept of more power, better fuel economy and reduced weight, size and cost.
The concept behind the technologies built into the two new MIVEC engines is also common to the A9-type engine jointly developed with DaimlerChrysler in 2004. The A9 engine currently powers Mitsubishi Colt and Colt Plus and enjoys high critical acclaim both in Japan and Europe. In addition to the core elements listed below, the new engines announced today incorporate other new and proprietary technologies. - Mitsubishi Innovative Valve timing Electronic Control (MIVEC)
- 4-valve direct-drive valvetrain
- Resin components (incl. intake manifold, head cover)
- Rear exhaust engine mounting layout
Both new MIVEC engines employ weight-reducing technologies such as the aluminum cylinder block to achieve a more than 10 percent weight reduction, which contributes to improved fuel economy and driving performance. Also, in order to assure high quality and reliability, these engines have been developed through strict development processes that conform to the MMDS (Mitsubishi Motors Development System) as well as the company's vehicle development processes.
1. Features of new 4-cylinder MIVEC engine
The new 4-cylinder 2.4-liter MIVEC engine employs MMC's proprietary intake and exhaust cylinder head port design and intake/exhaust systems to deliver best-in-class output power and torque. The engine uses MMC's proprietary MIVEC variable valve timing system, a double-wall stainless exhaust manifold and a high performance catalytic converter to deliver outstanding mileage and emissions performance.
