The burden for engine performance ultimately rests with fueling. After all, you ultimately undervalue yourself if you need more power to complement that cool air and hot sparks. Even worse, an inefficient fueling system might not be able to keep up with your whole arrangement. Therefore, this gap will eventually result in severe or costly engine damage. Therefore, it’s crucial to ensure the fuel injectors you’re employing are capable.
Clearly, substantial performance and engine durability difficulties may arise if the injectors have yet to be serviced and aren’t performing effectively. Fuel injectors demand regular cleaning if their health is unclear.
Therefore, you must take into account the essential functions of fuel injectors. The duty cycle range you run the injector in is among the most important things to consider, in addition to the injectors merely being worn out or polluted. Let’s explore the world of EV6 injectors and cover some fundamental highlights.
High-Impedance and Low-Impedance Injector: The Core Differences
Injectors with high and low impedances cannot be distinguished visually in a straightforward manner. Therefore, you must gauge the resistance between the injector’s two electrical connections. In simple terms, the injector’s coil’s resistance is what distinguishes the two.
- Typically, the resistance across the low-impedance injector falls between 2 and 3 ohms. You can use any basic voltmeter or ohmmeter to measure this resistance.
- On the other hand, high-impedance injectors are more typical in street applications. They employ a “saturated injector driver” in the ECU to save money. The typical resistance of modern high-impedance injectors falls between 10 to 14 ohms.
Injectors with low impedance employ a peak-and-hold driver. More current enables the injector to open more quickly and reliably with a particularly big injector and more significant fuel pressure. To open the injector, this controls current within a range of 4 to 10 amps, which is subsequently decreased to 1 to 2.5 amps to maintain the injector open.
Therefore, injectors may open more quickly thanks to the increased current, which is subsequently reduced to ensure that the current load is manageable. Other than the price, a peak-and-hold injector has no apparent drawbacks. Furthermore, none of the manufacturing systems include such variety due to the expense. Low-impedance injectors are most often used in applications designed specifically for racing due to all of these factors.
You must test the impedance of the OEM injectors and choose injectors that correspond to the impedance to identify the kind of injectors your car utilizes. You risk harming the vehicle’s ECU if you don’t. However, aftermarket ECUs can operate injectors with high and low impedances. Therefore, it is essential to consult the ECU’s documentation to confirm what the system supports in specific circumstances.
EV6 Connector Styles: The Varieties
Typical injector body type designations created by Bosch internally include EV1, EV6, and EV14. These body types are often utilized in the automobile industry. Bosch is not the only company in the sector, however. Also providing injectors to certain brands include Delphi, Denso, and other companies.
This is significant because, more often than not, the injector’s body design will reveal the connection it employs, which may be OEM-specific in certain situations.
However, chances are that your system employs one of the two most popular connection types: the more recent USCAR connector, which is square and has thinner, rounder prongs, or the older Jetronic/Minitimer style connector, which has a rectangular housing and two flat connecting prongs.
Flow Rate and Sizing: The Options
The maximum amount of fluid an injector will flow while operating wide open is known as the static flow rate. On the other hand, larger doesn’t always equate to better. You should remember that although you don’t want an injector that is too huge, you also don’t want one that is too small. There are drawbacks to both.
We know that too small injectors might result in the engine running low. So, what happens if you go too far the other way? Operation in the injector’s non-linear range as a result of oversizing is the main problem.
An injector will effectively flow at 50% of its capacity when it is open and closed normally, half on and half off. It will flow more or less linearly, depending on how much you open or shut it. However, the device will provide 30% less fuel if you lower the pulse width within its non-linear region.
This may lead to several performance and maneuverability problems. Running an injector outside of its linear range will make it exceedingly difficult to tune. Throttle responsiveness and idle quality will both suffer as a result.
