Injection nozzle

摘要

An injection nozzle for use in delivering fuel to a combustion space, the injection nozzle comprising a nozzle body (10), at least a part of which is provided with a first coating (14; 14a) arranged so as to reduce the temperature of at least a part of the nozzle body (10), in use. The coating (14; 14a) may have either a higher or lower thermal conductivity than the thermal conductivity of the nozzle body (10).
