ABSTRACT:
A fuel injection nozzle arrangement comprising a fuel injection nozzle having a fuel injection orifice, and vibratory means such as a piezoelectric crystal for vibrating the nozzle to cause atomization of fuel ejected from the nozzle through the orifice, the nozzle having a fuel-retaining valve at the fuel inlet side of the orifice arranged to normally close the orifice and thus prevent the injection of fuel but to be opened when the vibratory means is energised to permit injection of fuel, and the nozzle having a gas-excluding valve at the fuel outlet side of the orifice arranged to normally close the orifice and thus prevent the entry of gases into the nozzle through the orifice but to open under fuel injection pressure to permit the injection of fuel.
