What’s the difference between 6-hole and 7-hole nozzles?
For a given flow amount, a nozzle with a smaller number of holes and a larger hole size will develop a more powerful jet of fuel, which will penetrate deeper into the piston bowl. This means the fuel jet will have some resistance to ignition until it is farther into the bowl.
Conversely, a nozzle of the same flow amount, but with a larger number of holes and smaller hole size will produce a finer spray of fuel, which doesn’t penetrate as far into the bowl but ignites more readily. The amount of bowl penetration that is ideal depends on the RPM and boost level of the application.
At low RPM, the 7-hole nozzle atomises the fuel into the charge air better, which results in increased burn efficiency. However, there is a cross-over point around 2000 RPM where the deeper penetration of the 6-hole nozzle is required to maintain burn efficiency at higher levels of boost and RPM, as the charge air conditions in the bowl become increasingly dense and turbulent.
While apparent, these differences between 6 and 7-hole are minimal until 3000 RPM. Overall, the 7-hole nozzle is by far the most common, and is the best choice for most 24v applications. 6-hole injectors may perform better on trucks running a lot of boost and at higher RPM.
