2010 Mitsubishi i MiEV: What Is It?

0811_27_z2010_mitsubishi_i_mievfront_three_quarter_viewDo you think that America is finally ready for the very first electric city car?  Well, no matter if you think that we are or not, Mitsubishi thinks that we are and that is one of the main reasons why they have come up with the Mitsubishi I MiEV car!  This incredible car actually premiered earlier this year at the New York auto show and while it might be a Japanese-made car, it is actually completely electric and there is no gas needed for this car.

Are you curious as to how it works?  Well, it actually runs on lithium-ion batteries, which in total weighs about 450 pounds and they are attached beneath the rear seats.  You charge this car in the trunk area and to be honest, this car is going to be one hot car as soon as the concept is totally improved and all of the tweaks are worked out.

The Mitsubishi I MiEV is near silent and while it might not be a sports car, I have to say that the fact it can get up to 35 miles per hour, that is incredible!

Six-Zone Combustion Model for Direct-Injection Diesel Engines

Six Zone Combustion Model DieselAt Ecole Centrale de Nantes, France, researchers are building a new multizone combustion model for direct-injection (DI) diesel engines. The model recognizes six zones and provides local information such as the various zone’s temperature and the mean equivalence ratio. The engineers use different methods to find new in-cylinder combustion approaches to decrease emissions.

The six zones are the following:

  • “Liquid” zone
  • Air fuel mixture between the utmost liquid diffusion L and the lift-off length H.
  • The premixed combustion zone.
  • Diffusion combustion zone.
  • Diffusion flame surrounding zones.
  • Surrounding gas (air and EGR).

The model was analyzed on two-operating points at lesser load conditions. With the analysis, they found out that the new six-zone combustion model provides some new in-cylinder information in contrast to existing OD combustion models. It can also locate main trends when varying engine speed and load, exhaust gas recirculation (EGR) rate, or boost pressure and can also be utilized to translate experimental emission trends.
