| Function |
An injector open when current runs the the coil and closes, with the assistance of a powerful spring, when the current is cut.
The injectors have six holes, which means each injector produces six fuel jets. The holes are 0.14 mm in diameter. By way of comparison, a human hair is roughly 0.08 mm thick. This small diameter is necessary to atomise the fuel. The manufacturing tolerance is roughly one thousand of a mm.
The injection quantity is, for example, roughly 1 mm 3 for pilot injection. This can be compared to a drop of water which has a volume of roughly 30 mm 3 .
The injectors are a truly a precision instrument. It is therefore very important that there are no impurities in the fuel system.
