The fuel spray nozzle (24) is mounted at the end of a support rod (28) with a fuel supply channel (16). A valve (22,26) controls admission of oil to the nozzle. A motor (40) in line with the nozzle support drives a pump (10). The nozzle may be centrally mounted in an air intake. A flange (42) on the motor is bolted (44) to a housing or spider (32) connected to the sidewall of the intake.
