Nissan introduces new dual-injector system, for increased fuel-efficiency

Nissan announced that they have developed a dual-injector system to increase fuel-efficiency on its small-displacement petrol engines.

“The new fuel delivery system, the first of its kind in the world, uses an injector for each port rather than one per cylinder - speeding up fuel vaporization, reducing the amount of unburned fuel and reducing hydrocarbon emissions,” Nissan said in a statement.

Most current gasoline engines use one injector per-cylinder while Nissan’s Dual Injector system uses two injectors per cylinder, which reduces the diameter of the fuel droplets by about 60%.

“We consider it important to further improve the fuel efficiency of gasoline engines as demand for gasoline and other internal-combustion systems continues to increase around the world,” said Shuichi Nishimura, Corporate Vice President, Nissan Powertrain Engineering Division. “By widely applying the Dual Injector system on small-displacement engines, we hope to help reduce CO2 emissions and conserve rare metals.”

Nissan said that it will introduce the new system in production vehicles starting early in fiscal 2010.
