We\'ve said it before and we\'ll say it again - the internal combustion engine has a lot of life left in it. While we fully expect electric cars to make an impact in time, the reality is that the ICE\'s reign as sales leader won\'t be coming to an end for at least the next several years, possibly with a little assistance from biofuels. With that in mind, even mild efficiency improvements are always welcome to Otto\'s good old four-stroke engine.

Nissan believes its new Dual Injector System will offer a fuel mileage increase of roughly four percent, a small but important improvement. While larger displacement powerplants will be blessed with direct injection, small-bore motors will get the Dual Injector System. The Japanese automaker says the technology, which splits the fuel squirting duties through twin intake ports, reduces the diameter of fuel droplets by a substantial 60%, thereby improving vaporization.

Besides the obvious benefit of improved efficiency, Nissan claims its Dual Injector System costs 60% less than comparable direct injection technology. Plus, the system allows for a 50% reduction in the amount of rare precious metals in the catalytic converter. Check out the press release after the break for all the techy details.
