Abstract (en)
Fuel injection system comprises a piezoelectric injection valve, a fuel pump arranged in a fuel line upstream of the valve and a molecule separator arranged in the fuel line upstream of the pump and between the pump and fuel tank. The separator reduces the amount of polar components of the fuel, especially of non-dissolved water and/or alcohol molecules, tom non-polar molecules before feeding the fuel into the pump. Preferred Features: The molecule separator reduces the polar components of the fuel to less than 20 ppm. A sensor arranged between the separator and pump measures the amount of polar components downstream of the separator.
