Direct Injection!

Island_370

Audi (and others, I believe) have noticed some issues with direct injection. Without fueling going over the valves, nothing is "washing" them. Some of the Audi FSI (direct inj) motors are having valve issue. The build up is likely realed to the PCV, the EPA requires the motors digest the crankcase vapors. So I am not too excited to get a direct inject motor until these issues are resolved....be it valve coatings, secondary injectors in the intake, "scheduled" seafoam treatments....something.

Nissan Introduces New Dual Injector System - Worldcarfans
Nissan introduces a dual injector solution for small motors. On sale in the 2010 fiscal year

Nissan needs to hurry up and release DI for the V6! I hate waiting.

This is bad news. Because Nissan is going for a cheaper approach instead of offering Direct Injection that increases efficiency by up to 20% instead they offer us just a fancier injector that splits the fuel two ways for an increased fuel economy of a measly 4%. Shame shame shame. It's like buying an air to air heat pump for your house instead of a fancier geothermal heat pump which is far superior. It costs more up front but saves you money in the long run. Nissan is going the cheap route. I wonder when they will ever join the ranks of automobile manufacturers with D.I.? Shirley they won't be the last to adopt it will they? It's like being the last car company to adopt fuel injection instead of carburetors. Progress is slow...

Plan to have scheduled induction services if you want Stratified Injection. Misfires become a way of life with this continents fuel quality!!
