Nissan develops a new Dual Injector System

There are many vehicles, usually older cars, that are often having problems with the fuel system mainly because of worn down, clogged fuel injectors, or just not getting enough gas into the engine. Fuel injectors distribute the right amount of fuel to the combustion chamber in order to make the engine run. Based on my own personal experience and many of my customers from my job (Advance Auto Parts), the fuel system in cars tends to give problems due to the fact that the engine does not get enough fuel through the injector ports.


Fortunately, there is finally hope out there that will help solve these problems at least for one famous car maker. I was extremely surprised after reading a new technology article, “Nissan unveils new Dual Injector System to boost efficiency”, by Jeremy Korzeniewski from Autoblog because it is about time for this great capability to come out. Therefore, I will review this upcoming technology that hopefully will be incorporated in every new car from now on.



Nissan designed this modern dual injector system for small four cylinder engines in order to improve gas mileage. According to Jeremy, “Nissan believes its new Dual injector System will offer a fuel mileage increase of roughly four percent, a small but important improvement”. In addition, this new system will cost 60% less than its competition, direct injection technology, which is a very advance technology that many new cars manufacturers are using.




Even though Nissan believes this new system will help improve gas mileage, I am a little skeptic from this new dual injector system due to the fact that instead of using one injector per cylinder like most engines, Nissan will double the number of fuel injectors per cylinder. Of course, I agree that the engines will benefit incredibly from this latest technology by getting more fuel and preventing lack of gas or clogging. As Nissan Motor Co. states, “This reduces the diameter of the fuel droplets by 60%, resulting in smoother and more stable combustion”.

The new Dual injector System is great technological development by Nissan since it will encourage many other auto manufacturers to apply this efficient system in their new line of cars. I am really excited about this new technology because it would also be an amazing upgrade to high performance cars that are turbo or supercharged. The more fuel they get, the more torque and power they will produce. I just hope Nissan is accurate when it comes to the gas mileage improvement in its new system because it will be of tremendous help, even if is 4%, in these days where gas prices continue to rise.
