Patent ID: 7331535

Claim:
An injection nozzle for use in delivering fuel to a combustion space, the injection nozzle comprising a nozzle body, the nozzle body including a substantially conical tip region extending along a longitudinal axis of the nozzle body, the tip region including an outlet opening, the outlet opening being oriented substantially transverse to the longitudinal axis, at least a part of the nozzle body being provided with a first coating and a second coating applied to at least part of said first coating to form a multi-layer coating, said multi-layer coating ananged so as to reduce the temperature of at least a part of the nozzle body, in use, said first coating being formed from a material having a higher thermal conductivity than the thermal conductivity of the nozzle body, said second coating being formed from a material having a lower thermal conductivity than the thermal conductivity of the nozzle body.
