6.11. Check of productivity of fuel nozzles

1. Remove nozzles together with the fuel highway.
2. For supply of fuel to nozzles, a hose connect the fuel highway to the fuel supply pipeline.
3. Connect sockets to nozzles.
4. An additional wire connect nozzles to a wire (BRN) of the control unit and weight.
5. Include ignition.

6. Using a measured vessel, measure the fuel volume sprayed by a nozzle in 1 min.

Productivity of a fuel nozzle: 130 cm3/min.

7. If productivity of a nozzle differs from demanded, replace a nozzle.


At repeated installation fuel the highway and nozzles use new sealing rings, previously having greased them with a thin layer of engine oil.
